Getting on 'the GABA receptor shuttle' to treat anxiety disorders
There are increasingly precise molecular insights into ways that stress exposure leads to fear and through which fear extinction resolves these fear states. view more (2009-10-22)
Autistic brain has fewer neurons for processing emotion
For the first time, research has shown that the autistic brain has fewer neurons in an area related to emotion and social behavior, according to a new study published in the July 19 issue of The Journal of Neuroscience. view more (2006-07-20)
Rats Move Toward the Food but Do Not Eat
Scientists led a rat to the fatty food, but they couldn't make it eat. Using an animal model of binge eating, University of Missouri researchers discovered that deactivating the basolateral amygdala, a brain region involved in regulating emotion, specifically blocked consumption of a fatty diet. Surprisingly, it had no effect on the rat wanting... view more... (2009-09-09)
Children's National scientists uncover key developmental mechanisms of the amygdala
For the first time, scientists at Children's National Medical Center have successfully identified a key developmental program for the amygdala-the part of the limbic system that impacts how the brain creates emotional memories and responses. view more (2009-01-13)
How the brain handles surprise, good and bad
Whether it's a mugger or a friend who jumps out of the bushes, you're still surprised. But your response-to flee or to hug-must be very different. view more (2007-09-20)
Heightened level of amygdala activity may cause social deficits in autism
Something strange is going on in the amygdala - an almond-shaped structure deep in the human brain - among people with autism. view more (2009-03-20)
Brain protein linked to alcoholism and anxiety
Researchers at the University of Illinois at Chicago have discovered that a protein found in the brain is genetically linked to alcoholism and anxiety. view more (2005-10-04)
New study reveals brain cell mechanism of alcohol dependence
A study released today reveals a cellular mechanism involved in alcohol dependence. The study, in the May 28 issue of The Journal of Neuroscience, shows that gabapentin, a drug used to treat chronic pain and epilepsy, reduces alcohol intake in alcohol-dependent rats by normalizing chemical communication between neurons, which is altered by chronic... view more...

Impaired recognition of distress cues linked to psychopathic individuals
New research shows that children with psychopathic tendencies and psychopathic adults are unable to tell that another person is sad or frightened from their facial expression, and this may be due to functional abnormalities in part of the brain known as the amygdala. This was the finding of research by Derek Mitchell and James Blair of the... view more... (2000-09-12)
UC Davis M.I.N.D. Institute researchers find fewer neurons in the amygdala of males with autism
Researchers at the University of California, Davis, M.I.N.D. Institute have discovered that the brains of males with autism have fewer neurons in the amygdala, a part of the brain involved in emotion and memory. view more (2006-07-19)
Genes determine whether sugar pills work
It is a well-known fact in drug trials that individuals can respond just as well to placebos, sugar pills, as to the active drug. view more (2008-12-04)
Brain imaging can predict effectiveness of cognitive behavior therapy for treating depression
Whether or not cognitive behavior therapy (CBT) will help a person recover from depression can be predicted through brain imaging. view more (2006-04-03)
Neuroscientists identify how trauma triggers long-lasting memories in the brain
A research team led by UC Irvine neuroscientists has identified how the brain processes and stores emotional experiences as long-term memories. view more (2005-07-27)
Serotonin receptor: A rheostat in brain for emotion that may be linked to depression
Although drugs that target the brain's serotonin system are widely used to treat depression, the basic biological mechanism by which they help to alleviate symptoms is poorly understood. view more (2006-10-02)
Brain imaging reveals breakdown of normal emotional processing
Brain imaging has revealed a breakdown in normal patterns of emotional processing that impairs the ability of people with clinical depression to suppress negative emotional states. view more (2007-08-17)
Trust-building hormone short-circuits fear in humans
A brain chemical recently found to boost trust appears to work by reducing activity and weakening connections in fear-processing circuitry, a brain imaging study at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) has discovered. view more (2005-12-09)
Humans perceive others' fear faster than other emotions
You may not be fully dressed without a smile, but a look of horror will make a faster first impression. Vanderbilt University researchers have discovered that the brain becomes aware of fearful faces more quickly than those showing other emotions. view more (2007-10-15)
Scripps Research scientists find seizure drug reverses cellular effects
In the new research, published in the May 28, 2008 edition of The Journal of Neuroscience, the scientists found that gabapentin normalizes the action of certain brain cells altered by chronic alcohol abuse in an area of the brain known as the central amygdala, which plays an important role in fear- and stress-related behaviors, as well as in... view more...

Fear circuit flares as bipolar youth misread faces
Youth with bipolar disorder misread facial expressions as hostile and show heightened neural reactions when they focus on emotional aspects of neutral faces, researchers at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) have discovered. view more (2006-05-30)
Study suggests some brain injuries reduce the likelihood of post-traumatic stress disorder
A new study of combat-exposed Vietnam War veterans shows that those with injuries to certain parts of the brain were less likely to develop post-traumatic stress disorder (PTSD). view more (2007-12-26)
