In a 2007 episode of the television show Boston Legal, a character claimed to have figured out that a cop was racist because his amygdala activated — displaying fear, when they showed him pictures of black people. This link between the amygdala and fear — especially a fear of others unlike us, has gone too far, not only in pop culture, but also in psychological science, say the authors of a new paper which will be published in the February issue of Current Directions in...

New research examines the anxious brain during a fear conditioning task and provides insight into why some individuals may be more or less prone to anxiety disorders. The study, published by Cell Press in the February 10 issue of the journal Neuron, reveals neural mechanisms that may contribute to resilience against pathological fear and anxiety. The findings may help to direct therapeutic strategies for individuals who suffer from chronic anxiety as well as strategies that could help "at...

Mice previously exposed to traumatic situations demonstrate a more persistent memory of fear conditioning - acquired by associating an acoustic stimulus with an aversive stimulus - and lack the ability to inhibit this fear. This phenomenon is similar to that of people who suffer from Post-Traumatic Stress Disorder (PTSD), an anxiety disorder which appears after being exposed to highly traumatic situations, such as a violent attack, a natural disaster or physical abuse. In the study...

The brain is capable of holding and retrieving memories for specific fears, revealing a more sophisticated storage and recall capacity than previously thought, neuroscientists have found. The study, which appears in the journal Nature Neuroscience, may have implications for treating post-traumatic stress syndrome"”as scientists begin to understand how different fears are stored in the brain, they can move toward addressing specific fear memories. The research was conducted by...

Mizzou scientists find new research on the brain and fear that could help victims of Post Traumatic Stress Disorder The brain is a complex system made of billions of neurons and thousands of connections that relate to every human feeling, including one of the strongest emotions, fear. Most neurological fear studies have been rooted in fear-conditioning experiments. Now, University of Missouri researchers have started using computational models of the brain, making it easier to study the...

Fear is a powerful emotion and neuroscientists have for the first time located the neurons responsible for fear conditioning in the mammalian brain. Fear conditioning is a form of Pavlovian, or associative, learning and is considered to be a model system for understanding human phobias, post-traumatic stress disorder and other anxiety disorders.Using an imaging technique that enabled them to trace the process of neural activation in the brains of rats, University of Washington researchers...
