Katherine Heigl husband: Who is Grey’s Anatomy star Katherine Heigl married to? – Express

Katherine Heigl launched her career 16 years ago when she was part of the original cast of Grey's Anatomy on ABC. She has been in numerous films since then but her latest big hit has been in heartwarming drama Firefly Lane on Netflix. What do we know about Heigl's love life when she isn't in front of the camera?

Actress and model Katherine Heigl is married to singer-songwriter Josh Kelley.

The pair met when she was cast in the music video for his 2005 song Only You and there was an instant connection between them.

Heigl said: He was funny and charming, and we ended up having dinner that night.

"I had never dated a musician, and he was really sexy to me. Josh was really smooth.

"He asked me what my favourite flower was, my favourite fruit, even my favourite cut of steak.

"It must have been a line he used before, but I was intrigued.

Heigl continued: I decided I was sick of trying to figure out what everybody else wanted, and I should just decide what I want, and be honest, and not spend all my time guessing.

Josh is the first serious relationship Ive ever had where I was like: 'This is me. From the moment I met him, I said, 'This is what I want and what I need.'"

After a year of dating, Kelley popped the question and they tied the knot in 2007.

This year, Heigl and Kelley will be celebrating their 14th wedding anniversary.

Heigl said: Josh and I always said that cheating would be a deal-breaker, there is no second chance.

"But Ive seen friends and acquaintances go through it and theyve found a way back to the relationship, and a way to forgive each other.

As much as I would kill him if he cheated because it would destroy me, I have started to question whether, if a mistake were to be made and it was a one-time thing, I would forgive him. Because look at the life weve built together."

Much like Heigl in real life, her Grey's Anatomy eventually did get her happy ending.

Izzie was in a serious relationship with Dr Alex Karev (played by Justin Chambers) but they decided to go their separate ways in season six.

Alex did move on with Dr Jo Wilson (Camilla Luddington) but in series 16, he left Grey Sloan Memorial Hospital for good to rekindle his previous romance with Izzie.

He had found out she had his twins while they weren't together after using their frozen embryos following their break.

Izzie, Alex and their young children are now spending their lives together on a farm in Kansas.

Grey's Anatomy is available to watch on ABC.

Watch Lakeith Stanfield Being Interrogated in Judas and the Black Messiah – The New York Times

In Anatomy of a Scene, we ask directors to reveal the secrets that go into making key scenes in their movies. See new episodes in the series on Fridays. You can also watch our collection of more than 150 videos on YouTube and subscribe to our YouTube channel.

A handful of questions asked during an interrogation in Judas and the Black Messiah are key to propelling the plot of this tense historical drama.

Set in the late 1960s, the movie follows William ONeal (Lakeith Stanfield), a young man who becomes an informant, feeding the F.B.I. intelligence about the Chicago Black Panther Party and one of its leaders, Fred Hampton (Daniel Kaluuya.) This early scene comes after ONeal is caught using a fake F.B.I. badge to steal a car.

Narrating the sequence, King says the moment is about the danger of being apolitical. ONeal is asked his feelings about the assassination of the Rev. Dr. Martin Luther King Jr. and admits to being upset. But when asked about the killing of Malcolm X, he has more of an indifferent response. We really wanted to hit home the old phrase, if you stand for nothing youll fall for anything, King narrates.

Jesse Williams Reveals His Thoughts On When ‘Grey’s Anatomy’ Will End – Just Jared

Jesse Williams is weighing in on the rumors that Greys Anatomy could be ending with seasons 17.

The 39-year-old actor, who plays Dr. Jackson Avery on the long-running show, spoke to Entertainment Tonight about the series ahead of its return in March.

I think the show is too important to go out without a damn parade, Jesse says, even when considering the effects of the pandemic. Without us really knowing and having a real finale season where these writers are so overworked and depressed and in a rat race to try and get material out without all this uncertainty, thats not the ideal scenario.

He added, I think they, and all of us, kind of deserve to have the time and space to map out how to end. Its just a flattering way of saying I hope not.

Jesse isnt the only Greys star to open up about the shows potential end.

Ellen Pompeo did too, and heres what she said

Anatomy of a disinformation campaign | Any harm in a hashtag? Spotting disinformation in the wild – News24

Unlike the spreaders of misinformation, who dont mean harm, disinformation actors knowingly cause damage to people, social groups, organisations and even countries. In the second of a three-part series examining falsehoods on Twitter, Jean le Roux sorts misinformation from disinformation in three popular hashtags.

1. #RamaphosaResigns: Parody turns political

When a young comedian from Sebokeng tweeted about giving people mini heart attacks with the hashtag #RamaphosaResigns, he might not have set out to cause harm.

But the viral hashtag was co-opted by anonymous accounts to drive a false politically motivated narrative that South African president Cyril Ramaphosa had resigned and misinformation turned into disinformation.

Missed part one in the series? Read it here. The final part is at this link.

Chief among the agitators was @Advovolicious, an anonymous Twitter account that was spun off the @AdvBarryRoux account. @Advovolicious falsely claimed that Ramaphosa would announce his resignation during a public address that evening, in July 2020. In reality, Ramaphosa would give a briefing on the governments Covid-19 relief efforts.

The @Advovolicious account repeatedly tweeted the falsehood that South Africas president would resign.(Screenshot)

The initial tongue-in-cheek jab from the Jan Van Potgieter (@SciTheComedist) parody account was lost in the resulting noise.

A social network graph of the original tongue-in-cheek tweet about Ramaphosas resignation, indicating how small it was compared to the larger conversation.

In a strange twist, the same @SciTheComedist account started the #VoetsekANC hashtag, apparently in response to an #ANCFriday campaign by ANC supporters.

2. #VoetsekANC: The campaign that wasnt

Like clockwork, #VoetsekANC surged on Fridays, as the regular spikes in mentions show. (The Afrikaans voetsek can be roughly translated as piss off.) On the surface, it appeared to be a coordinated campaign targeting the ANC.

Social media listening tools like Meltwater Explore show regular spikes in mentions of #VoetsekANC.

High-follower Twitter accounts engaged with the hashtag on a weekly basis, usually around service delivery or government-linked corruption.

But a deeper dive shows that the traffic is organic.

The #VoetsekANC hashtag found traction across the political spectrum.

The hashtag has been used by leaders in the Economic Freedom Fighters (EFF) and Democratic Alliance political parties, as well as accounts from conservative, libertarian, liberal andnationalist groups. The diverse nature of these accounts, spanning the political and ideological spectrum, makes it unlikely that it is a coordinated and inauthentic disinformation operation. A snapshot of the use of #VoetsekANC on 6 December 2020 makes this clear.

Several communities, indicated in different colours, have actively engaged with the #VoetsekANC hashtag for their own reasons. They represent a broad spectrum of political ideologies.

3. #PutSouthAfricansFirst: A wide-ranging disinformation campaign

The #PutSouthAfricansFirst hashtag was used 945,000 times by slightly more than 115,000 individual users, and at times trended many times per week in 2020. (Note: The numbers have declined since the beginning of December, when there were 144,000 accounts and 1.15 million mentions. It appears Twitter has taken action against several of these accounts.)

The phrase Put South Africans First was used by the African Transformation Movement during its campaign ahead of the 2019 national election. But the hashtag became prominent in April 2020, when the @ulerato_pillay Twitter account used it to take a swipe at EFF leader Julius Malema.

The tweet that put #PutSouthAfricansFirst on the map.

The account was deactivated after the DFRLab identified its owner as Sfiso Gwala, a dismissed South African National Defence Force member from Richards Bay in KwaZulu-Natal. It has since been replaced with the @lerato_pillay account. This was likely done to erase the accounts history and associated evidence.

The network consists of a core of accounts aggressively retweeting and engaging with narratives that tap into South Africans discontent with crime, unemployment and poor service delivery.

The largest share of this traffic consists of retweets (65%) and quote tweets (21%) with only 6% of tweets using the hashtag being original. This low share could indicate that a small number of accounts are coordinating original tweets, while the rest simply amplify their message.

The bulk of #PutSouthAfricansFirst content on Twitter is retweets.

Real issues, false content

The narratives spread by the proponents of the hashtag touch on real issues such as unemployment, crime and lack of service delivery. What makes it disinformation is the disproportionate blame these tweets place on foreign nationals in some cases based on made-up facts.

For example, on 14 August 2020 the @uLerato_pillay account posted a photo of a crowded hospital with patients sleeping on the floor. The tweet claimed that South African patients were suffering because foreign nationals were taking up hospital beds. A reverse image search revealed that the photo was taken at a Nigerian hospital in April 2019 almost 16 months before Gwalas tweet.

An example of false context one of seven types of mis- and disinformation identified by anti-misinformation organisation First Draft. The photo is genuine but it is shared with false contextual information.

Several #PutSouthAfricansFirst tweets that used made-up statistics have since been deleted. For example, in September 2020 Gwala claimed that 70% of the University of South Africas employees were foreign nationals. But Unisa says 97% of its full-time and fixed-term staff are South Africans.

Examples of fabricated content used in the #PutSouthAfricansFirst campaign.

Despite hashtag users claims that it is a patriotic movement, much of the content is openly xenophobic. Users have described foreign nationals as cockroaches a term reminiscent of the Rwandan genocide.

Accounts that interacted with #PutSouthAfricansFirst content have called foreign nationals leeches, parasites and cockroaches.

All this had the effect of serving, for several months, as a dog whistle for people who buy into xenophobic narratives or become convinced that the real problem is foreign nationals. The result is clear: replies to Gwalas tweets urge violence against foreigners. (Gwala failed to respond to a request for comment by the time of publication.)

Coordinated behaviour

The network consists of a core set of accounts that create and share xenophobic narratives. Other accounts, some operated by real individuals who buy into the narratives, then retweet and engage with the content. The disproportionate amount of traffic that comes from a small share of accounts points to coordination and disinformation.

A representation of the number of original tweets versus the total number of tweets (including retweets and replies) using #PutSouthAfricansFirst. The total volume closely tracks the original tweets during large spikes, suggesting some level of coordination.

For example, in July 2020 #PutSouthAfricansFirst was mentioned 165,120 times by 32,044 authors. But the top 10 accounts that used the hashtag only about 0.03% of the total accounts were responsible for 1.25% of the tweets. The same disproportionate volumes were seen in November 2020, when the top 10 accounts were responsible for 5.6% of the tweets despite making up only 0.04% of the unique accounts that used the hashtag.

In November 2020, #PutSouthAfricansFirst was used in 122,000 tweets and by about 24,800 Twitter users. But the 10 most vocal accounts were responsible for a disproportionately high number of mentions.

A network graph using 3,200 recent tweets from each of the 10 most active users of #PutSouthAfricansFirst (as at 4 December 2020) shows who they interacted with most often.

A social network graph of the 10 most vocal accounts that used #PutSouthAfricansFirst (left) and the accounts they interact with the most (right), suggesting that the vocal accounts were propping up the accounts in the middle.

When you strip away some of the noise, it is clear that these 10 accounts engage with, retweet and reply to many of the accounts involved in the #PutSouthAfricansFirst network. In essence, this means a small cluster of accounts are aggressively engaging with the accounts in the centre and each other in an attempt to create the perception of a legitimate movement.

Prolific retweeters

A closer look at the accounts engaging with and retweeting this content reveals suspicious behaviour such as a high volume of retweets on a single topic.

One of the most vocal accounts in November 2020 was @Hlabezulu3, created on 30 October 2020. Despite being a brand new account, it tweeted 7,387 times, peaking at 380 tweets in a single day on 24 November 2020. That is an average of almost one tweet every four minutes. Most of these tweets were retweets from several #PutSouthAfricansFirst accounts.

Twitter has since suspended the account.

An analysis of the @HlabeZule3 Twitter account while it was still active. The account mainly retweeted accounts within the #PutSouthAfricansFirst network (right), and posted large volumes while doing so.

Another prominent account in this network, @bsfs1212, tweeted 578 times on 26 November and 564 times on 27 November 2020 alone. Not even the departed were off limits in this campaign. The Twitter account of Faith Gwedashe-Ndamase, a former Mrs South Africa finalist and Alex FM radio host who died in a car accident in September 2017, was repurposed to target journalist and author Nechama Brodie* with antisemitic tweets. Gwedashe-Ndamases profile pictures and user handle were changed, her bio altered and her previous tweets deleted before rebranding as the @MProphet101 account.

Archived replies to Faith Gwedashe-Ndamases tweets show that @ndamsexf and @MProphet101 share the same Twitter user ID.

What these case studies show is that a small, coordinated group of individuals can take real issues, taint them with their own agendas and then spread the repurposed narrative with relative ease on social media. A joke quickly turned into a negative PR campaign against Ramaphosa based on the actions of one influential account that twisted the #RamaphosaResigns hashtag. A small, active and coordinated group of accounts distorted facts and maligned foreign nationals under the auspices of a patriotic #PutSouthAfricansFirst movement.

The success of such campaigns mainly hinge on tapping into existing prejudices against a political party, organisation or a group of people to exploit it for the disinformers agenda.

By contrast, #VoetsekANC developed organically. It transcended political and ideological boundaries to become an event that was almost celebrated weekly.

Neuroscience Explains What Happens to the Brain When One is in Love – Science Times

Love makes someone feel euphoric, foolish, happy, distracted, exhausted, obsessed, passionate, and many more. In other words, love does so much that in the brain that it can control one's behavior.

There are a lot of changes in the brain of a person in love that affects the body, making the person feel both desirable and undesirable feelings at the same time.

As Valentine's Day comes close, take a moment to marvel and appreciate the incredible effect of your partner on your brain! Here are the things that happen within your brain when you are in love according to neuroscience.

According to Science Focus, scientists use functional magnetic resonance (fMRI) and Event-related potentials (ERPs), two brain scanning techniques, to understand what is happening inside the brain when a person is in love.

The fMRI creates an image of the brain that shows which parts of the brain are activated when in love and when a person is in different circumstances.

Meanwhile, the ERPs measure the changes in brain activity as it responds to different stimuli. It is very time-specific that gives signals on a millisecond timescale.

Behavioral neuroscientist Dr. Sandra Langeslagexplains that the ERPs are mostly used to study attention. In an experiment to see how brains work when the person is in love, the researchers presented a photo of the participant's partner and recorded the brainwaves present.

They found two brainwaves with ERP components that indicate immediate and sustained attention and are usually larger in people who are in love.

"This is the example of 'if you know your beloved drives a red Ford, you'll see those everywhere because they remind you of them'. We're getting a picture of the brain to help us understand these experiences," Langeslag explains.

In another experiment, she measured the influence of love on one's attention on tasks and found out thatattention tends to be diverted to the other person, slowing the performance of tasks.

Then a 2017 study also found "neural synchrony" was higher in romantic couples compared to those paired with strangers. The researchers found synchronized patterns between the brains of people in a romantic relationship.

According to HuffPost, falling in love causes a major hormone rush. That means that when people first fall in love, they experience a Bush of their hormones to the brain. These hormones are oxytocin, dopamine, and adrenaline.

Oxytocin is said to be the love hormone that mediates the reward and motivation systems in the brain. It is also associated to be the reason for forming longer bonds with other people.

While dopamine is called the pleasure hormone that that fire up relationships and maintain them. In the love language, this hormone responds to falling in love, staying in love, and breaking up.

Meanwhile, other hormones activated when in love are adrenaline that makes the heart beat faster, creating that fluttery excitement, attraction, and euphoria.

Laboratory of programmable functional materials headed by Kostya Novoselov is to open at MIPT – Newswise

Newswise The laboratory of MIPT alumnus, 2010 Nobel Prize laureate Kostya Novoselov will become the first project of the new center for research in the field of brain, neuroscience and consciousness under the leadership of Professor Tagir Aushev, head of the MIPT Laboratory of High Energy Physics, corresponding member of the Russian Academy of Sciences (RAS). The goal of the center is to carry out fundamental research about the functioning of the human brain, the nature of consciousness, and development of appropriate technologies. The activities of the laboratory of Novoselov, which will be operating at MIPT, will be focused on inventing new methods to study the human brain. Among them there are high-sensitivity sensors, brain-computer interfaces, as well as development of a technological basis for future neuromorphic processors.

The donation of 500 million rubles (6.7 million US dollars) of Vladimir Potanin, billionaire investor and philanthropist, allows to open the laboratory and cover all the costs of the first five years. During this period researchers plan to make the first simple devices based on two-dimensional materials and then continue with the physical imitation of neural communication, neuromorphic computing networks and "smart membranes". The development of these technologies will enrich our knowledge about the brain and the nature of consciousness, which can help a large number of people in the future.

The goal of the new center for research in the field of brain, neuroscience and consioucness is the development of one of the most prospective areas of research brain studies. It involves physics, mathematics, biology, psychology and other disciplines. The project is designed for the next 10-15 years, and the Center's laboratories will be formed in the next 2-3 years in various areas of neuroscience. The first one is the laboratory of programmable functional materials which will be located in the Phystech.Digit building of the MIPT Dolgoprudny campus . We are planning to cooperate closely with the MIPT Center for Photonics and Two-Dimensional Materials.. The laboratory will be set up by the end of this year, said Aushev.

UTEP Professors Study May Lead to Solutions for Overeating – Newswise

Newswise EL PASO, Texas Science is a step closer to a new response to obesity, thanks in part to a study conducted by a team that included Sergio Iiguez, Ph.D., associate professor of psychology at The University of Texas at El Paso.

The 10-member team led by Brandon Warren, Ph.D., assistant professor of pharmacodynamics at the University of Florida, made discoveries about a specific area of the brain tied to recollection and the desire to seek and consume food. It could lead to a way to inhibit the desire to overeat.

Iiguez, who directs UTEPs Iiguez Behavioral Neuroscience Lab and helped design novel experimental techniques for the research, said that people tend to overeat when exposed to cues or environments that remind them of treats, which is one reason why people opt for dessert even after a filling meal. The study showed that neurons in a specific part of the brain control the link between the cue (seeing the dessert) and the action (ordering the dessert). Iiguez and team found that animal subjects consumed fewer treats when they regulated that region of the animals brain.

The techniques and the data eventually could help overcome some issues linked to obesity such as stroke, Type 2 diabetes, high blood pressure, high levels of bad cholesterol, and coronary heart disease.

This is a big discovery because we now have experimental tools that allow us to turn off neurons while the subjects engage in a specific behavior, Iiguez said. This research shows that a specific part of the prefrontal cortex of the brain is important for the initial stages of learning to seek food.

Research results were published recently in eNeuro, a journal of the Society for Neuroscience.

The latest journal publication comes on the heels of a successful 2020 for Iiguez, when his research was published in three top journals: Neuropsychopharmacology, Biological Psychiatry and Proceedings of the National Academy of Sciences of the United States of America.

The University of Texas at El Paso is one of the largest and most successful Hispanic-serving institutions in the country, with a student body that is 83% Hispanic. It enrolls nearly 25,000 students in 166 bachelors, masters and doctoral programs in 10 colleges and schools. With more than $100 million in total annual research expenditures, UTEP is ranked in the top 5% of research institutions nationally and fifth in Texas for federal research expenditures at public universities.

Can Robots Be Engineered To Actually Feel Pain? – Walter Bradley Center for Natural and Artificial Intelligence

Recently, an article in Neuroscience News made some confusing claims, especially the claim that robots can have experiences in the same sense as living entities can. Lets look at some of them:

In an article from HSE University in Russia about about developing robotic intelligence based on the human brain, we read:

Today, neuroscience and robotics are developing hand in hand. Mikhail Lebedev, Academic Supervisor at HSE Universitys Centre for Bioelectric Interfaces, spoke about how studying the brain inspires the development of robots.

One identified goal is to merge biological organisms with machines, to create cybernetic organisms (cyborgs). Given that the human brain does not really behave like a computer and that many functions of human thought are non-computational, there may be limits to how far that can go. But we shall see.

We then read,

In addition, a robot can experience the sense of touch just like a human a robot can have skin, it can feel touched. And then it doesnt just move randomly in space: if it touches an obstacle, it senses it and reacts to it just like a human does. It can also use this artificial tactile information to grip objects.

Robots can even simulate sensations of pain: some forms of physical contact feel normal and some cause pain, which drastically changes the robots behaviour. It starts to avoid pain and develop new behaviour patterns, i.e. it learns like a child who has been burned by something hot for the first time.

Note how the text slides effortlessly from can experience the sense of touch down to simulate sensations of pain.

Lets be clear about this: The robot feels no actual pain. A dog feels pain if you inadvertently step on his tail. That is because he is a living creature and pain is something his self experiences.

Granted, his is a minimal self, in the sense that he lacks reason and moral choice. But it is a self. He experiences life as a dog and he has feelings and opinions generated by that experience. A robot is not alive and does not have a self of any kind. There is no known way to cause a robot to have a subjective consciousness, which the dog naturally does. So roboticists resort to fudging between simulations of feeling and actual feeling.

Further from the same article:

In addition, robots can learn from humans. A robot can perform actions in an infinite number of ways, but if it wants to mimic a human, it must observe the human and try to repeat their movements. When it makes mistakes, it compares itself with how a human performs the same action.

Yes, provided that that is what the robot was programmed to do. There is no self in there. Not in the sense that, when a puppy is trained to heel or fetch, or avoid jumping up on guests, we are communicating with his self, to instill proper social behavior. We dont program the puppy. We teach him, the way his mother would except that we teach him different things.

A robot can interact with the nervous system through a bi-directional interface: the nervous system can send a command signal to the robot, and the robot from its sensors can return sensory information to the human, causing real sensations by stimulating nerves, nerve endings in the skin, or the sensory cortex itself. Such feedback mechanisms make it possible to restore the sensation of a limb if it has been lost. They are also necessary for more precise movements of the robotic limb, since it is on the basis of sensory information received from the arms and legs that we correct our movements.

Absolutely, and the discover that the human brain can manipulate electronic signals quite efficiently if the interface is delicate enough is the most promising development in prosthetics in many decades. But, to be clear, it is the human who is experiencing the sensation; the robotics is merely obeying commands from the central nervous system.

The paper requires a subscription.

Recently, a Japanese research team created a child robot called Affetto, for which claims are made that it can feel pain. The theory is that it could help robots understand and empathize with their human companions:

Scientists from Osaka University have developed a synthetic skin that contains sensors to subtly detect changes in pressure, whether its a light touch or a hard punch. This artificial pain nervous system was then hooked up to a life-like android robot child that was able to react to the sensations using a variety of facial expressions.

At least the report put feel in quotation marks.

At Science News, we learn more: If robots can experience pain themselves, they might understand human pain better, too:

Sensors embedded in soft, artificial skin that can detect both a gentle touch and a painful thump have been hooked up to a robot that can then signal emotions, Minoru Asada reported February 15 at the annual meeting of the American Association for the Advancement of Science. This artificial pain nervous system, as Asada calls it, may be a small building block for a machine that could ultimately experience pain (in a robotic sort of way). Such a feeling might also allow a robot to empathize with a human companions suffering.

Agan, empathize is in quotation marks. Because, the reality, unwilling as the roboticists are to admit it, is that only life forms can empathize because only life forms can actually suffer. A robot can be programmed cleverly to appear to empathize or suffer. But there is nothing in there but programming.

The most recent project with Affetto is a body, complete with artificial skin covered-skeleton covered in the new tactile sensor.

Why do this?

Japan has already rolled out robots in nursing homes, offices, and schools as a way to deal with its aging population and shrinking workforce The theory goes that these robots will able to communicate with humans more authentically and effectively if they give the impression they are capable of feeling like us.

Life forms human, animal, plant, fungus communicate in various ways, usually with others of their kind. They are alive and they have needs. The robots will not communicate at all. They only carry out their programming. Its unfortunate if seniors living in institutions are stuck with robots for company but lets not delude ourselves about what is happening.

One person who senses this is prominent University of Southern California neuroscientist Antonio Damasio:

A robot with tactile sensors that can detect touch and pain is along the lines of having a robot, for example, that smiles when you talk to it, Damasio says. Its a device for communication of the machine to a human. While thats an interesting development, its not the same thing as a robot designed to compute some sort of internal experience, he says.

Damasio believes that it might be possible to program a robot to actually have feelings, through homeostasis. But there is no known way to give something that isnt alive the actual experiences of liveness, only ever more clever simulations.

Expect, however, to see a good deal of carefully articulated confusion on that point.

Consumers were not buying robots as friends this year. (2018) But robotic pets are helpful for patients with dementia in long-term care. A live animal might not be safe or well-looked after in that situation.

BXCL501 is an investigational, proprietary, orally dissolving thin film formulation of dexmedetomidine, a selective alpha-2a receptor agonist for the treatment of agitation and opioid withdrawal symptoms. BioXcel believes that BXCL501 directly targets a causal agitation mechanism, and the Company has observed anti-agitation results in multiple clinical studies across several neuropsychiatric disorders. BXCL501 has been granted Fast Track Designation by the U.S. Food and Drug Administration for the acute treatment of agitation in patients with schizophrenia, bipolar disorders, and dementia. BXCL501 has been studied in two Phase 3 trials (SERENITY I and II) for the acute treatment of schizophrenia related agitation and bipolar disorder related agitation, respectively, and in a Phase 1b/2 trial (TRANQUILITY) for the acute treatment of dementia related agitation. This product candidate is also currently being evaluated in a Phase 1b/2 study (RELEASE) for the treatment of opioid withdrawal symptoms, with plans to initiate a Phase 2 trial in hospitalized patients suffering from delirium related agitation within the next several months.
