The NIHs Diversity Obsession Subverts Science – The Wall Street Journal

The National Institutes of Health supports a multidisciplinary neuroscience initiative to expand understanding of the brain. Research applications include treatments for Alzheimers, Parkinsons, autism and depression. On June 10, NIH director Francis Collins announced a new requirement for participating in the brain initiative. Neurologists, molecular biologists and nanophysicists seeking NIH funding must now submit a plan showing how they will enhance diverse perspectives throughout their research. Scores on the plan for enhancing diverse perspectives will inform funding decisions.

This new requirement is part of Dr. Collinss continuing effort to atone for what he calls biomedical sciences stain of structural racism. The NIH already supports more than 60 diversity and inclusion initiatives, but those have apparently failed to eradicate NIHs own systemic and structural racism.

Each plan for enhancing diverse perspectives must show how the principal investigator will empower individuals from groups traditionally underrepresented in biomedical research, such as blacks, the disabled, women and the poor. Institutions are also covered by the diversity mandate. Researchers working on an NIH neuroscience grant should be drawn from institutions that are traditionally underrepresented in biomedical research, including community-based organizations.

Dr. Collins provided no evidence for structural racism other than demographic data on NIHs grant applicants and recipients. Black applicants are present in far fewer numbers compared with their representation in the US population, 13.4%, according to Dr. Collinss announcement. In 2020 black scientists made up 2.3% of the 30,061 funding applications the NIH received. Less than 2% of NIH grants go to black principal investigators.

To Dr. Collins and his academic peers, such disparities are virtually irrefutable evidence of discrimination, though grant reviewers dont see an applicants race. But the use of population data as a benchmark for assessing institutional racism ignores racial disparities in academic skills, achievement and study practices that the NIH didnt cause and couldnt possibly do anything to remedy.

How do babies perceive the world? – MIT Technology Review

Its Ursulas third time in the functional MRI machine. Heather Kosakowski, a PhD student in cognitive neuroscience, is hoping to get just two precious minutes of data from her session. Even though Ursula has been booked to have her brain scanned for two hours, its far from a sure thing. Her first two sessions, also booked for two hours each, yielded only eight minutes of usable material combined.

The task verges on the impossible. Kosakowski needs Ursula to stay both awake, watching projected images of faces and scenes, and very still, ideally for seconds or even minutes at a time. Every twitch and wiggle blurs the MRIs scan, obscuring the image and rendering it useless. But Ursula tends to squirm and then, inevitably, fall asleepexactly what you would expect from a six-month-old baby.

Scanning infants brains while theyre awake is incredibly difficult and time consuming, and theres always a risk that a session will produce no data at all. A motivated adult is capable of staying perfectly still for two hours, yielding brain images that read like an open book. Ursulas sessions produce something more akin to a book thats been torn up and thrown in a river. Kosakowski, who is jointly advised by cognitive neuroscience professors Nancy Kanwisher 80, PhD 86, and Rebecca Saxe, PhD 03, needs to carefully fish out the usable sections and stitch them together before she can read the story they reveal.

Heather is probably the most skilled person alive today at getting high-quality functional MRI data from human infants, says Kanwisher, the Walter A. Rosenblith Professor of Cognitive Neuroscience.

If Kosakowski doesnt get the two minutes of still brain images she needs, its possible Ursulas two previous visits will have been for nothing. But if she can get a clear fMRI reading, she will be one step closer to answering one of the most profound questions in modern neuroscience: What are the physical underpinnings of the human mind?

Kosakowski is no stranger to overcoming obstacles. Her childhood was characterized by the sort of instability that made any kind of higher education feel unattainable. Her father was in the military, so her family moved around a lot. Then her parents divorced, and the difficulties multiplied. When she was about seven, she and her mother moved into a homeless shelter, and at 11, Kosakowski was put into foster care in Western Massachusetts. Having a bachelors degree was always my dream, she says, but she calls her first attempt at college a dismal failure.

RACHEL FRITTS

I dropped out, I was homeless and had no job, and then I totaled my car and I was like, what am I going to do with my life? she recalls. She decided to enter the Marine Corps but hoped she might someday get a second shot at college.

After several years in the military, Kosakowski left the Marines and returned to Massachusetts, enrolling part time at Massachusetts Bay Community College. Maybe, she thought, a bachelors degree wasnt so far out of reach after all. She set her sights on Smith College, where she was admitted. But around the time she received that piece of news, she also got another: she was pregnant.

Kosakowski didnt go to college anywhere that fall, but her eagerness to learn persisted. Her natural curiosity found an outlet in her baby, Hannah, who was born that October. She watched Hannah experience grass for the first time in the spring, delighting at how she reacted to this strange new material covering the ground. As Hannah explored her environment, Kosakowski kept wondering what things looked like from her perspective. What was she experiencing? How was she making sense of the world around her?

When Hannah was two, Kosakowski got a job at a nonprofit that was working to speed up research on multiple sclerosis, giving her the opportunity to attend a neuroscience conference. After that I was kind of hooked, she says. I was like, okay, the thing I really want to be doing is research, and in order to do research I need a degree. I have to go back to school.

Kosakowski was accepted to Wellesley Collegea school she had written off years before because it was so competitive. She became fascinated with neuroscience, peppering her professors with questions until one said, Heather, some of the questions you ask, nobody knows the answer. You should get a PhD.

Just as Kosakowski graduated from Wellesley, Saxe was looking for a manager for her lab, which happened to be one of the only labs in the world studying babies in MRIs while they are awakeand consequently one of the only ones that could answer Kosakowskis questions about the nature of infant cognition. She applied for the position and got it.

When her foster sister had a baby, Kosakowski went to Saxe and asked if she could learn how to use the fMRI to scan the infants brain. I think she thought Id just scan my niece and be done with it, Kosakowski says. But I just kept scanning, and she never told me to stop. Saxe, impressed with Kosakowskis work and determination, agreed to take her on as a graduate student. In 2017, she left her job as lab manager and began her first semester as a PhD candidate at MIT.

Kanwisher still remembers the first time she saw Kosakowski scan a baby in the MRI. She was considering working with Kosakowski and Saxe on their infant study, but at first she was highly skeptical. This kid is squealing like crazy. The mom is nervous. The whole thing is stressful. And this goes on and on and Heathers not giving up, she says. Thenboom. The clouds part, the kid smiles, Heather pops the kid into the MRI scanner, and like a minute later she scans beautiful data. Just the persistence, the skill, is spectacular.

Kosakowskis current study focuses on how the brains of babies just two to nine months old respond to short videos of faces or bodiesand how that differs from their response to scenes without people. She is the first to find evidence of this kind of specialization in children under five years old. The information shes after can only be measured with fMRI. Magnetic resonance imaging allows researchers to take high-resolution pictures of cross-sections of the brain. Functional MRI adds another layer to this, recording images of brain activity in real time. When neurons in one section of the brain are particularly active, blood flow increases to fuel that region. This shows up as a bright spot on fMRI scans.

Researchers have spent decades using fMRI to prove that sections of the adult brain are highly specialized for certain tasks, and to pinpoint exactly which areas are specialized for which functions. The mind and brain have all this structure. Were not just generically smart. Were smart in very particular ways about very particular things that humans do, Kanwisher says. If you look at the structure, you see this set of dozens of regions of the brain, each that does a very distinctive, different thing Its impossible to look at that and not wonder, How did that structure get wired up?

When adults look at faces, for instance, a section of the brain called the fusiform face area, or FFA, lights up. In other words, if researchers put adults in MRI machines and show them images of both faces and objects, the FFA will only respond to faces. The parahippocampal place area (PPA), meanwhile, responds most strongly to depictions of scenes. Kanwisher herself named the FFA after leading the team that discovered it in 1997, and she led the effort to pinpoint and describe the PPA in 1998. She and her colleagues also discovered the brain section known as the extrastriate body area (EBA), which responds strongly to pictures of body parts, in 2001.

[Heather is] scanning the youngest awake humans that anybody can scan and asking what structure is in the brain within a few months of birth, Kanwisher says. And thats just one of the most thrilling questions in all of psychology, neuroscience, and deep philosophy: What is the structure of our minds and where does it come from?

Preliminary results from Kosakowskis study provide some of the strongest evidence yet that some functions of our brain may be innate rather than learned. Babies also have selective responses for faces, bodies, and scenes in the FFA, EBA, and PPA, Kosakowski says. Nobody has ever found that before. And it was completely not expected that we would find that.

HEATHER KOSAKOWSKI

The covid-19 pandemic, though, has brought its own set of challenges. The fMRI sessions had to be put on hold, and she has spent much of the last year analyzing her data at home. Covid-19 has greatly impacted me in that I am working from home full time and also a single parentthe same way its impacted lots of families with children, Kosakowski says. She hopes to have the opportunity to scan more infantsto begin studying their auditory processing before graduating in May 2022. But Ursulas session in late 2019 turns out to have been one of her last chances to get precious data for her dissertation.

In that session, Ursula had fallen asleep in the scanner, but Kosakowski was in high spirits as it wrapped up. She was pretty sure shed managed to get the dataand shed later confirm she was right. As Ursulas mother left to change out of MRI-friendly scrubs, Kosakowski scooped up the groggy baby and held her as she sat in front of a computer. The unflappable grad student has an uncanny ability to keep babies happy and relaxeda skill no PhD program will teach you, but one thats invaluable when every extra second of clean data helps.

Finally, she pulled up the image shed been looking for, pointing toward the screen as Ursulas gaze followed her finger. Someday, thanks to their combined efforts, we might have a better understanding of how Ursula perceived the image before her. Look! Kosakowski told the baby in her arms. Thats your brain!

UCI Podcast: The perils and benefits of dream incubation – UCI News

It sounds too crazy to be true: Corporations and scientists using sounds and smells to influence peoples dreams. But targeted dream incubation is not limited to the realm of science fiction. Scientists use the method to help patients overcome addictions such as smoking, and corporations have launched advertising campaigns that encourage willing participants to participate in having their dreams shaped.

Sara Mednick, a professor of cognitive neuroscience at UCI, is worried about the potential misuse of dream incubation and recently joined about 40 other sleep and dream scientists in signing an open letter voicing their concerns. In this episode of the UCI Podcast, Professor Mednick discusses how dream incubation works, and how sleep keeps people healthy.

When the sleeping mind hears certain sounds or smells certain odors, the landscape of dreams shifts. Some memories are reinforced, while others grow dim. By manipulating sounds and smells, scientists and corporations are able to influence our dreams and thus our waking lives.

What are the dangers and benefits of this kind of targeted dream incubation? And how do our dreaming hours keep us healthy?

From the University of California, Irvine, Im Aaron Orlowski and youre listening to the UCI Podcast. Today, Im speaking with Sara Mednick, a professor of cognitive neuroscience at UCI.

Professor Mednick, thank you for joining me today on the UCI Podcast.

SARA MEDNICK

Thanks for having me, Aaron

ORLOWSKI

So you, along with about 40 other sleep and dream scientists, recently signed an open letter raising some alarms about a new type of advertising called targeted dream incubation. Listeners might have heard of this because Molson Coors, the beer company, generated a lot of headlines about this back in January and February when they announced a plan to use this advertising method around the Super Bowl. So I want to ask you: What is dream incubation and how does it work?

MEDNICK

The first thing to kind of understand is that sleep is a time when we are processing our recent experiences and were folding them away and putting them into long-term storage areas where they can be safe and not overwritten by the next days experiences. The idea that you could kind of interfere with this memory processing time or this sleep time has been talked about for a century, at least. But it wasnt until about 15 years ago, 10 years ago, when researchers realized that if you pair the thing that you want to remember with a specific sound while youre trying to learn it.

So if youre trying to learn the position of a lot of different objects and where they go in a puzzle and each puzzle piece has an objects face on it like a cat or a tea kettle or a dog or a car. And all of these objects have a specific sound. The cat sounds like a meow and the dog sounds like a ruff, right? And every time you place that cat puzzle piece in the specific position it goes into the puzzle, you hear the meow sound. So you tie that sound to that position in the puzzle. When you then go to sleep, you play the meow sound, right? And you play say, maybe theres a hundred puzzle pieces. Maybe you play only 50 of those puzzle pieces. And then you wake up the next day and you see how many of those puzzle pieces do you remember their location? It turns out that those sounds that you played in the middle of the night, biased that memory processing to actually only focus on the puzzle pieces that had the sound played. It reactivated specific memories, and it made the memory process focus on only those memories.

And so what happens is your performance for just the memories that you reactivated during sleep. Well, Coors decided that they could use this idea in order to make you have an association between the Coors beer and very specific sounds that were the sounds of a mountain stream or birds chirping or beautiful like very refreshing feelings and sounds. And then when they went to sleep, the subjects were played those sounds again, and woken up, right after they were probably dreaming for awhile with those sounds in their heads. And they asked them, well, what were you dreaming about? And they were dreaming about Coors.

ORLOWSKI

Wow. So this could work for any variety of objects or subjects or ?

MEDNICK

Yeah, anything you can pair a sound to. But it doesnt just have to be a sound. It could be a smell. If there was a specific thing that you wanted somebody to associate, we could use targeted memory reactivation, where we target specific memories to be reactivated during sleep. And we can increase peoples memories. But its also been shown that we can actually make people forget certain memories by doing this targeted memory reactivation. So its like a targeted forgetting, very similar to the Spotless Mind movie, where people were trying to take out memories of long lost loves that they missed, their heartbreaks. And you could actually take out that memory. Well, this is exactly that idea that you can actually during sleep, instead of remember things more, you can actually delete things.

ORLOWSKI

That is crazy. And the movie Eternal Sunshine of the Spotless Mind was quite trippy. And if I remember the characters wanted to reverse their forgetting in the end.

MEDNICK

Yeah. Its, I mean, theres just a whole bunch of potential things that it can be used for, that some of them are really great. Theres beautiful research looking at people who are smokers who want to stop smoking. And during sleep, they send in the smell of cigarette smoke into the noses of the sleeping subjects. And at the same time, they pair that smoke with the smell of rotting fish. And what they find is that that creates a negative association with the smoking. And when people wake up in the morning, they dont want to smoke.

ORLOWSKI

So this sort of dream manipulation and memory adjustment, can be used for different purposes, helping an addict overcome their smoking addiction. But also we just talked about Coors using it to encourage people to want to drink more beer. So why are you concerned about this method being used by corporations?

MEDNICK

You know, back in the day before we knew about subliminal messaging manipulating people unconsciously to buy products, there was a lot of advertisements that were sent very quickly through films and you couldnt even see them and suddenly youve got the urge to drink Coke, you know, or eat more popcorn, or whatever it was. And that was outlawed because its unfair. Its unfair that people unconsciously are being driven to do things that they dont even realize that theyre being manipulated to do. So thats, thats that thats been regulated by this point. And those rules only really actually applied to waking experience. And the thing about the law is that you need to actually be very specific or people will get around it. You need to really say, okay, you cant do the subliminal messaging, either in wake or sleep.

And particularly because sleep, youre actually even more vulnerable to messaging than you are during wake, because youre sleeping. You dont remember anything. Subjects never remember that they had sounds played or smells played. And so you have no sense of when youre being manipulated or not. The Nest system has an algorithm that knows when people are sleeping in that room. And if thats the case, then they could also play music, they can play whatever sounds that they want. And so its not a far shot to say that if you know when someones asleep, you can add information into their sleep that would be unbeknownst to them.

ORLOWSKI

Well, so weve been talking a lot about the potential nefarious uses of this type of messaging in peoples dreams, but maybe we can talk a little bit more about why people dream in the first place. What function does it serve for people to have dreams?

MEDNICK

Its a great question. And if you find out the answer, I hope Im the first person that you tell. Nobody knows. Weve been trying to figure out this question for centuries. And its one of the earliest questions known to man and woman, because weve always dreamed. Evolution hasnt pushed it away and we still dream. And we still dont know why. Theres many hypotheses. You know, Im a cognitive scientist, so I look, maybe those dreams that are helping you rehearse the information that you just learned during the day. And that may help you with that long-term storage mechanism I was talking about.

You know, dreams also have emotional content to them. And so theres an idea that while youre dreaming, youre actually rehearsing and playing out certain kinds of scenarios. Maybe youre saying, well, what would I do if an ax murderer was running after me? Like, hmm, let me see that again you know, like these recurring nightmares. Like, what would I do in this case where somebody dumps me or whatever it is. And so you have these kinds of recurrent scenarios in your mind to see, like, what are different potential strategies and outcomes that I could choose?

At the neuroscience level, the idea is that with emotional experiences, we are uncoupling the emotional areas of the brain from the memory areas. And over time, these experiences that are at first rather really emotional actually become less emotionally charged and more kind of cognitively charged, where we can start to think about them a little more rationally over time. And thats a very natural process that happens with emotional experiences and it requires sleep to have a natural progression such that, you know, eventually that breakup that you thought youd never recover from in a month, youre like, yeah, all right, well, I did this wrong or, you know, she did that wrong, or whatever it was that you want to say.

ORLOWSKI

Yeah. Unless youre in Eternal Sunshine of the Spotless Mind, in which case you just regret it eternally,

MEDNICK

And then you just keep making the same mistakes over and over and over.

ORLOWSKI

Yeah. Well, so it sounds like sleeping and dreaming essentially helps us heal. So how does our mood change after weve slept or after weve dreamed?

MEDNICK

Theres obviously the idea of sleep on it youll feel better in the morning. And it turns out that sleep may help you feel worse in the short term and better in the long-term. And you could imagine why, right? If something happened to you while you were walking home, you know, you decided to take the darker route home, and something happened to you, you dont want to just forget that thing. Its actually really protective to have a strong, emotional response to a negative experience. And what has happened is you actually have a stronger emotional response right after you wake up in those first few days. Youre really living inside that emotional response. And then over time that emotional response starts to waiver or just decrease. And what you get is this stronger and stronger cognitive response. Those are really natural protective mechanisms that teach us not to do these things that didnt work out anymore.

ORLOWSKI

Yeah. Well, you mentioned earlier that we are especially vulnerable to messaging while were asleep and, and more so than when were waking. And I guess on one level that seems kind of intuitive, but can you tell us more about why thats the case?

MEDNICK

Many people wake up and they have no idea what they dreamed, right? Your hippocampus is a brain area that takes in new information. And sometimes its, its on, a of the times its on during sleep, but the part of the brain that really connects to the long-term memory and to really storage and to holding on the information, is also the frontal cortex. And the frontal cortex when youre sleeping is totally turned off. So you may have this connections to what recently happened and then what happened 10 years ago to you, and you have these dreams that are making wild connections between all these different experiences and that recent thing that just happened to you.

But when you wake up in the morning, you dont remember any of these things. And thats probably a good idea, right? Because you really want to focus on the things that are real. And the dream time may be some subconscious practice that youre getting through, some process that youre working through. But you dont want to hold onto your dreams per se, more than your waking life. So its actually sort of evolutionarily better to not necessarily be carrying your dreams around all day, but that also means that you dont know what happened to you in the middle of the night, if your dreams were suddenly full of Coors commercials.

ORLOWSKI

Yeah. You might not know how that got there, how those arrived.

MEDNICK

Yeah, you definitely wouldnt.

ORLOWSKI

Yeah, well, and I want to ask you one final thing. If I just want to get good sleep, what steps should I take? Youve studied many people or many components of sleeping and how to increase quality sleep. So what are the best actions to take?

MEDNICK

Theres so many different things that can be done. And theres a whole list of any website will tell you what sleep hygiene tips to take. But some of the ones that dont necessarily get recommended, but I recommend is getting to sleep early. Because the sleep that you get in the first part of the night is different than the sleep that you get in the morning. So the idea that you can get to sleep late and then sleep a little bit later in the morning, youre not actually getting the sleep thats the really good sleep. Whats called slow-wave sleep happens in the first part of the night. And thats the stuff that does all the clearance of toxins from the brain. And when people get older, they have less and less slow-wave sleep and more and more buildup of these toxins that can lead to the plaques that develop with Alzheimers. And also a lot of this memory consolidation stuff that weve been talking about all happens during slow-wave sleep. So really getting to sleep early, Im talking like 10 p.m., is very important for getting that early deep sleep that is the most restorative that we have.

Another thing is to make sure that when you wake up in the morning, you go outside and you get some sun. We are rhythmic animals and the sun is the strongest whats called entrainer, basically. Its the downbeat for our day. And when you get bright light early in the morning, that sets you up to actually be ready for sleep at night. And if you dont have bright light, maybe its the winter time and youre on the East Coast or something, get one of these really strong all spectrum lights and just have it for 15 minutes on while youre having your breakfast in the morning. I could go on and on, but reduce blue screens after 6 p.m. The blue light is really strong inhibitors of melatonin, which is a sleep hormone. And so you want to make sure that after 6 p.m., youre really trying not to get in front of any fluorescent lights or any lights that dont have some filters on them.

ORLOWSKI

Professor Mednick, thank you so much for joining me today on the UCI Podcast.

A new class of memory cells discovered in the brain – Tech Explorist

How the brain recognizes the faces of familiar individuals has been important throughout the history of neuroscience. But the proposed cells that link visual processing to person memory are not found yet.

A new study reported the discovery of such cells in the brains temporal pole region that links face perception to long-term memory. Scientists from the Rockefeller University have a new class of memory cells that collectively remembers faces.

Scientists used fMRI as a guide to zoom in on the TP regions of two rhesus monkeys. They then recorded the electrical signals of TP neurons as the macaques watched images of familiar faces and unfamiliar faces that they had only seen virtually on a screen.

When subjects had seen familiar faces, their neurons in the TP region were highly selective. After processing the image, these neurons found to fastdiscriminating between known and unknown faces.

Strangely, these cells responded threefold more strongly to familiar over unfamiliar faces despite the fact that the subjects had seen the unfamiliar many times on screens.

Neuroscientist Sofia Landi, first author on the paper, said, This signifies the importance of knowing someone in person. Given the tendency nowadays to go virtual, it is important to note that faces that we have seen on a screen may not evoke the same neuronal activity as faces that we meet in person.

Winrich Freiwald, professor of neurosciences and behavior at The Rockefeller University, said,The cells of the TP region behave like sensory cells, with reliable and fast responses to visual stimuli. But they also act like memory cells that respond only to stimuli that the brain has seen beforein this case, familiar individualsreflecting a change in the brain due to past encounters. Theyre these very visual, very sensory cellsbut like memory cells. We have discovered a connection between the sensory and memory domains.

The discovery of the TP region at the heart of facial recognition means that we can soon start investigating how those cells encode familiar faces. We can now ask how this region is connected to the other parts of the brain and what happens when a new face appears. And of course, we can begin exploring how it works in the human brain.

In the future, the findings may also have clinical implications for people suffering from prosopagnosia, or face blindness, a socially isolating condition that affects about one percent of the population. Face-blind people often suffer from depression. It can be debilitating because in the worst cases, they cannot even recognize close relatives.

This discovery could one day help us devise strategies to help them.

There’s A Simple Way To Feel Happier, According To The New Science Of Emotion : Shots – Health News – NPR

Back in the fall, Michelle Shiota noticed she wasn't feeling like herself. Her mind felt trapped. "I don't know if you've ever worn a corset, but I had this very tight, straining feeling in my mind," she says. "My mind had shrunk."

Shiota is a psychologist at Arizona State University and an expert on emotions. When the COVID-19 crisis struck, she began working from home and doing one activity, over and over again, all day long.

"I will be honest, for the past 14 months, I have spent most of my waking hours looking at a screen, either my laptop, my phone or a TV screen," she says, often from the same sofa, in the same room in her San Francisco home. All that isolation and screen time had taken a toll on Shiota.

During the pandemic, many people have felt their mental health decline. The problem has hit essential workers and young adults, ages 18 to 24, the worst, the Kaiser Family Foundation reported in May. The percentage of adults with signs of anxiety or depression has grown threefold, from about 10% to 30%.

Although some people are starting to test the waters of public life again, planning vacations and socializing more, others may still have lingering signs of what psychologists call languishing. They may feel an emptiness or dissatisfaction in day-to-day life. Or feel like they're stuck in weariness or stagnation.

Luckily, an emerging area of brain science has a new way to help lift yourself out of languishing and bring more joy into your life. It worked for Shiota.

"I had to expand my consciousness," she says. And she did it by intentionally cultivating a particular emotion.

Explore ways to cultivate well-being with NPR's Joy Generator.

For thousands of years, there's been a common belief in Western culture about emotions that they are hard-wired and reflexive, psychologist Lisa Feldman Barrett writes in the book How Emotions Are Made: The Secret Life of the Brain. "When something happens in the world ... our emotions come on fast and uncontrollable, as if somebody flipped a switch," she writes.

But when researchers look at what's going on inside the brain and inside the body during specific emotional states, the theory doesn't hold up.

Over the past decade, neuroscientists have begun to shift how they think emotions arise. Rather than being inevitable, hard-coded experiences, researchers now think emotions are malleable, and people have more influence over them than previously thought.

Say for example, you're walking in the woods, and you see a grizzly bear, says neuroscientist Anil Seth at the University of Sussex. "You recognize it's a bear," he says, "and then what happens?"

Previously researchers thought the emotion comes first. "You see a bear and then you feel afraid," Seth says. "Because you're afraid, your brain then jacks up your adrenaline levels."

Your heart rate rises. Your breath quickens. Your pupils dilate. And blood rushes to your skeletal muscles. The old theory was that "the fear sets in train all kinds of flight and fight responses so that you are well-prepared to run away and live another day," he adds. In other words, the emotion (i.e., fear) triggers the physiological responses (i.e., an adrenaline rush).

But according to the latest research, the human body probably works the other way around, Seth says. "The brain registers a grizzly bear, and that perception sets in train all the physiological responses." You get an adrenaline rush. Your heart rate goes up. You start breathing faster. Blood rushes to your muscles. And then the emotion comes.

The brain senses these physiological changes and decides which emotion to conjure up. The emotion is an interpretation of what's going on both inside the body (the adrenaline rush) and the outside of the body (the sight of the bear). "The brain has to figure out what caused the sensory signals," Seth says.

The chosen emotion not only helps the brain make sense of these signals, but it also helps the brain predict better the immediate future and how to handle the situation at hand. Which emotion would be most useful? Which emotion will help me survive?

To figure that all out, Seth says, the brain uses one more piece of information and this part is key. The brain takes into account your past experiences, your memories.

Let's return back to that encounter with the grizzly bear. If your past experiences with bears come largely through news reports of attacks and maulings, then your brain will likely interpret your bodily sensations raised heart rate, raised blood pressure, sweaty palms as fear. Lots of fear! And this emotion will help drive you away from the bear. "So you can live another day," Seth says.

But what if your family hunts for a living? And your past encounters with a bear ended in a wonderful feast for you and your neighbors. Then your brain may interpret the adrenaline rush the heavy breathing and raised heart rate as excitement. This positive emotion will help drive you forward toward the bear, while all the physiological changes help you bring home dinner.

"Your brain uses memories from the past in order to create the present," says Barrett, who also does neuroscience research. "It's bringing knowledge from the past to make sense of the immediate future, which then becomes your present."

Neuroscientists call this "the predictive brain." Understanding how these predictions work is "very powerful knowledge," Barrett says. It means that emotions aren't hard-wired reactions to particular situations, which are out of your control (i.e., you see a bear and therefore you must feel afraid). But rather it's the opposite. "You can, in fact, modify what you feel in very direct ways," she says.

It's not about trying to force a happier or less fearful feeling in the moment, Barrett says. But rather, it's all about planning ahead. You can stack the deck in favor of your brain, choosing positive, uplifting emotions in two major ways, she says.

The first one is a no-brainer: You can take care of your body physically. According to this new theory, the brain constructs emotions based largely on physiological signals and other sensations from your body. So by boosting your physical health, you can decrease the chance your body will send unpleasant signals to your brain and, in turn, increase the chance, your brain will construct positive emotions instead of negative ones. "You can get more sleep. You can eat properly and exercise," she says.

The second approach to influencing your emotions may be less familiar but likely just as impactful: You can "cultivate" the emotions you want to have in the future.

"If you know that your brain uses your past in order to make sense [of] and create the present, then you can practice cultivating [positive] emotions today so that your brain can automatically use that knowledge when it's making emotions tomorrow," Barrett says.

By practicing particular emotions, you can "rewire" your brain, she says. "Your brain grows new connections that make it easier for you to automatically cultivate these emotions in the future." So when you start to feel a negative emotion, such as sadness or frustration, you can more easily swap that negative feeling for a positive one, such as awe or gratitude.

"For example, when I am video chatting with somebody in China, I can feel irritated very easily when the connection isn't very good," Barrett says. "Or I can feel awe at the fact that someone can be halfway around the world, and I can see their face and hear their voice, even if it is imperfect, and I can be grateful for that ability."

In this way, emotions are a bit like muscle memory. If you practice the finger patterns for a chord on the piano, a few minutes each day, eventually your fingers can play those chords with little thought. The chords become second nature.

The same goes for emotions. To help pull out of the pandemic blues, it's time to start "practicing" positive emotions and it won't take as much as learning all the chords.

All you need is about five to 10 minutes, says psychologist Belinda Campos at the University of California, Irvine. "Hopefully it wouldn't take people as much effort as it does to eat healthier or to exercise," she says. "Positive emotions feel good. I think people will find them rewarding enough to return to them and keep doing them."

Scientists say this practice is helpful to prevent or work with everyday doldrums and weariness. It isn't intended as a replacement for treatments, such as counseling and medication, for serious mood disorders or anyone going through intense or prolonged bouts of depression.

A few decades ago, scientists used to lump together all kinds of positive emotions into one concept: happiness. Since then, a group of psychologists, including Campos and Shiota, figured that there is a whole "family tree" of positive emotions, including pride, nurturant love, contentment, nostalgia, flow, gratitude and awe.

One reason these emotions often make us feel good is they shift our focus away from the self that is "me and my problems" and onto others, Campos says. "They help put the self in its balanced place, of not being absolutely the highest thing on the to-do list. They help us focus on the joys that relationships can bring."

She adds, "In this way, positive emotions are part of what helps you to put others before the self." And helping others often makes people feel good. "So, for example, people report levels of higher well-being when they're giving to others, and it can feel better to be on the giving end rather than the receiving end," she says. "I think that's more evidence that focusing on others can be really good for us."

The idea of cultivating positive emotions is pretty simple. Choose one of these emotions and then do a specific action regularly that helps evoke it. Psychologists have devised suggestions for how to get started, but it can be as simple as taking time to notice and appreciate the small things around you that uplift you. (Read three tips to get started at the end of this piece.)

Over time, your brain will start to use these emotions more often and turn to negative emotions less frequently.

Take, for instance, gratitude.

For the past year and a half, Dr. Sriram Shamasunder has been on the front lines of the COVID-19 pandemic. Shamasunder is a physician at the University of California, San Francisco, and he spends about half his time in low-income communities around the world.

To help bring more "light" into his life, Shamasunder started to keep a gratitude journal. It was part of a project for the Greater Good Science Center at the University of California, Berkeley.

Each day, Shamasunder simply jotted down things around him for which he was grateful. "So not necessarily spending a whole lot of time racking my mind, but just everyday occurrences that were powerful or meaningful or just simple and beautiful," Shamasunder told The Science of Happiness podcast. He jotted down the doctors and nurses working on Sunday, "the unseen hands who created a vaccine," "the evening light, magical and orange and blue," and a tree outside that provides refuge to birds, ants and squirrels.

By intentionally cultivating gratitude, for even a short period each day, Shamasunder found it easier to evoke positive feelings throughout the day. "The act of naming the gratitudes carried into the next day and the next, where I became more aware of things in my life that I should cherish in the moment, or I need to cherish."

Back in the fall, when Shiota, the Arizona State psychologist, felt her mind shrinking, she knew exactly which emotion she needed to cultivate.

She got up off the couch, drove West from her San Francisco home and ended up at the edge of the ocean. "I am trying to reconnect with the vast natural world, with the universe beyond my professional and personal responsibilities, and beyond this moment in time," Shiota writes in the Annals of the New York Academy of Sciences. "I am searching for awe."

Shiota is a world expert on awe. She says the emotion is difficult to define, "but I think that what we are dealing with is a change that happens in our mind and in our bodies and in our feelings when we encounter something so extraordinary that we can't explain it."

That encounter can be with something grand, such as a panoramic view of a red sun dipping into the Pacific Ocean. It can be with something minuscule, such as the black spots on a ladybug. (How did they get so perfectly round?) It can be a scent, a taste or sound. "It can be a very complex and powerful song that you've never heard before or even a scene in a TV show," Shiota says.

Whatever it is, the extraordinariness of the event makes you pause, for a bit, Shiota says, and try to figure it out. How does a rose smell like a lemon? Why does a perfectly ripened peach taste so good? "We simply slow down our body, slow down," Shiota says.

And this pause calms your body. "I've found evidence that the activation of our fight-flight sympathetic nervous system dials back a little bit."

The feeling of awe also widens your perspective, she says which Shiota desperately needed after spending so much time looking at screens. "I had to consciously force myself to look further away. I had to let my senses my sight, my sound, take in a broader scope of what was going on around me."

In addition to going to the beach, Shiota also simply walked around her neighborhood, looking for unexpected and inspiring things.

"There was this amazingly elaborate, chalk drawing in recognition of somebody's birthday. There was a couple, in which one person was clearly helping the other learn to roller-skate on the San Francisco hills. And they're clinging on to each other for dear life," she says with a chuckle. "Then the flowers! If you look closely at flowers, in a way that you never take the time to do, you'll see how incredibly intricate they are.

"So the opportunities for awe are there," she says. "Look for what moves you, what pushes your sense of boundaries of what is out there in the world."

It took a little time and patience Shiota says, but eventually these "awe walks" helped her recover from her pandemic funk. Practicing awe released her mind from that constraining "corset."

"Then my mind was able to spread out and take up the space that it needs to take to feel OK," she says. And once her mind released, her body followed. "When you take off the corset, your whole body goes, 'Oh, oh! That's much better.' "

Psychologists say you can improve your well-being if you recognize moments of positive feelings, value them and seek them out more often. Below, find a few other ideas for cultivating positive emotions and turning happiness into a habit. To explore more ideas, check out NPR's Joy Generator.

1) Share some appreciation: Campos recommends this simple practice. Get together with some friends and write out on cards three things that you're grateful for in the other person. Then share the cards with each other.

"We're using this task right now in my laboratory, and it seems to be very evocative of positive emotion," she says. And though the data is preliminary, she says, "what we see so far is that people enjoy writing what they appreciate in others, and they enjoy sharing it with the other person. It seems to be affirming bonds." Sometimes it even ends in hugs.

2) Take an awe walk: Take a five-minute walk outside each day where you intentionally shift your thoughts outward. Turn off your cellphone or even better don't bring it with you. "Focus your attention on small details of the world around you," psychologist Piercarlo Valdesolo at Claremont McKenna College suggests. Look for things that are unexpected, hard to explain and delightful.

For example, take a moment and find a crack in the sidewalk, where a weed is poking out, Barrett says. And let yourself feel awe at the power of nature. "Practice that feeling over and over again," she says. "Practice feeling awe at colorful clouds, an intricate pattern on a flower or the sight of a full moon."

3) Listen to a calm concert: A recent meta-analysis from the University of Michigan found that sounds of nature, including birdsongs and water sounds, lower stress, promote calmness and improve mood. Find a bench in your neighborhood under a tree or near water. Sit down, close your eyes and consciously listen to the natural sounds around you. Listen for birdsongs, rustling wind or trickling water. Try sitting for at least five minutes whenever you get a chance. Allow and enjoy calm to wash over you.

Limits for human embryo research have been changed : This calls for public debate – Down To Earth Magazine

The new regulation makes it possible to conduct research on human embryos that are at more advanced stages of development

For 40 years, research into early human development has been guided by the principle that after 14 days, an embryo should not be used for research and must be destroyed. This rule has been part of the law of more than 12 countries. But new guidelines released by the International Society for Stem Cell Research have removed this rule. This makes it possible to conduct research on human embryos that are at more advanced stages of development.

Now, countries must revise their laws, policies and guidelines to reflect this change. But first, public debate is crucial to determine the limits of what sort of research should be allowed.

Over the decades human embryo research has allowed us to understand normal and abnormal human development, as well as early genetic diseases and disorders. Studying human embryos, as the earliest forms of human life, can give us insight into why miscarriages occur, and how our complex body systems develop. Human embryos are also important for stem cell research, where researchers try and create cell-based therapies to treat human diseases.

Often, extra embryos are created during in-vitro fertilisation procedures. These extra embryos may be donated for research. They are cultured (or grown) in a laboratory and can be studied until they reach day 14 post-creation.

The 14-day rule has served as an international standard since 1990 when it was included in the Human Fertilisation and Embryology Act in the United Kingdom. At the time that it was introduced, it was not possible to keep human embryos alive in a laboratory for more than a few days. However, scientists have been recently been able to keep embryos alive for longer periods, between 12 and 13 days. The ethical, legal and social consequences of such research were also important considerations.

The 14-day rule and the new guidelines

Although the 14-day rule has been criticised as being arbitrarily decided, there are a number of reasons for the time frame.

After an egg cell is fertilised by a sperm cell, the resulting embryo consists of a few identical cells. Most embryos will implant in the uterus after the 14th day. After this point, the primitive streak appears, which is the first sign of an embryos developing nervous system. The rule also identified the point at which the embryo shows signs of individuation, because it is no longer possible for the embryo to split into twins after 14 days. Some people reason that due to these events, it is at this stage that a moral being comes into existence, and it would not be ethical to perform research on embryos after this time.

There has been increasing pressure from some researchers to remove the 14-day rule, or at least extend it, as it prevents critical research from being undertaken. Extending the rule would allow important research into early human development to be done. The new guidelines make it possible to do research on embryos older than 14 days if the approval processes of the relevant ethics committees are followed.

A significant problem, however, is that there is no longer any limit on the time frame for research. Would it be permissible to do research on human embryos that are 20 days old or 40 days old? The guidelines specify no limit. The longer a human embryo is allowed to grow, the more recognisably human it becomes. At what point would we regard the research unethical, and at what point does the moral cost outweigh the benefits of research?

What the law says

Countries around the world take a variety of approaches to human embryo research. Some like Italy and Germany dont allow it at all. Others, like the UK, allow research to continue until the embryo is 14 days old, after which it must be destroyed. There are also some which permit embryo research without identifying a limit. Some, like the United States, do not have any law regulating it (but there are guidelines which contain reference to the 14-day rule).

In South Africa, reference to the rule is found in the National Health Act (2003), which states that human embryo research may only be done with permission of the minister, and that the embryos must not be older than 14 days.

International guidelines are not legally binding. But the effect of the revised guidelines is that the international standard for best practice in scientific research has now changed. This means that countries which have implemented the rule in their laws will need to revise them so that they are in line with best practice in science.

The future of human embryo research

Human embryo research is a sensitive topic because people are divided on the moral status of the human embryo. Some people believe that the embryo, as the earliest form of human life, should be protected and not subjected to research at all. Others believe that while an embryo has some moral status, it cannot be protected in the same way as humans are, and may be used for some important research which could ultimately benefit people.

The decision to discard the 14-rule appears to have been made without public input. That does not encourage the public to trust in science, and public engagement should have come before such an an important rule was changed.

There are a number of approaches to working with the revised guidance. Bioethicist Franoise Baylis has suggested that project-specific time limits should be identified, based on the minimum amount of time required to address the stated research objectives. This would mean that some research would still be subject to the 14-day limit, while other studies would be permitted to exceed it. Another approach would be to keep the 14-day limit as the norm, and consider applications to exceed it case by case. Or the limit could be extended to 28 days.

The coming conversations surrounding embryo research will prove to be very important. The proverbial genie is out of the bottle, and public debate is crucial.

COVID Infection Unlikely to Jeopardize IVF Success, Small Study Suggests – MedPage Today

Women who were previously infected with COVID-19 did not have decreased chances of success with assisted reproduction treatment, according to a small observational study.

Among a cohort of 46 patients with prior SARS-CoV-2 infection, there were no significant differences in average anti-Mullerian hormone (AMH) levels before and after they got sick (1.73 vs 1.61 ng/ml, respectively), reported Maria Cruz Palomino, PhD, of the IVI Madrid fertility clinic.

For women with a normal ovarian reserve, AMH levels -- which indicate a woman's ovarian reserve status -- declined from 4.6 to 3.1 ng/ml. However, this decrease was unlikely to compromise a patient's ability to produce eggs for fertilization, said Palomino during her presentation at the European Society of Human Reproduction and Embryology annual meeting.

"Generally, the data showed no variation in AMH levels before and after SARS-CoV-2 infection," Palomino said in a press release. "We could assume that the chances of success in [patients'] fertility treatment remained intact."

Palomino added that while the researchers did observe a small drop in AMH levels among recovered COVID-19 patients with normal ovarian reserve, the decrease likely would not affect the chances of achieving pregnancy, and may not even be attributed to SARS-CoV-2 infection.

Albert Hsu, MD, an assistant professor of clinical ob/gyn at the University of Missouri in Columbia, who was not involved in this study, said that while these findings provide some information about SARS-CoV-2 and fertility, more data are needed before stating that COVID-19 infection does not impact chances of IVF success. Additionally, Hsu stated that AMH levels, which the study authors used to indicate ovarian reserve status, may not actually convey how likely it is for in vitro fertilization (IVF) patients to conceive.

"Anti-Mullerian hormone is a great predictor of how many eggs I am going to get when I stimulate a woman with IVF," Hsu told MedPage Today. "It very much does not predict pregnancy."

Because SARS-CoV-2 binds to the ACE-2 receptor, which is widely expressed in the ovaries, some have raised concerns about how COVID-19 infection might affect ovarian reserve, Palomino's group stated. However, initial studies have shown no correlation between COVID-19 and loss of fertility in reproductive-age women.

In this study, Palomino and colleagues recruited patients from 11 clinics in Spain who had IVF between May and June of 2020. All 46 study participants had documented baseline hormone levels before receiving a positive test for COVID-19.

Researchers analyzed AMH levels as an indicator of their response to fertility treatment. Around 16 participants had a low ovarian reserve (AMH <1 ng/ml), and 30 had normal ovarian reserve status (AMH 1 ng/ml). The average age for patients with low and normal ovarian reserve was 39 and 35, respectively.

AMH levels remained stagnant in women with low ovarian reserve, from 0.8 ng/ml before infection to 0.7 ng/ml afterward.

Palomino and colleagues emphasized that this was a small study, and is not robust enough to inform public health recommendations. Additionally, because this is an observational study, results are limited by potential confounding.
