Mildly stressful situations can affect our perceptions in the same way as life-threatening ones Financial loss can lead to irrational behavior. Now, research by Weizmann Institute scientists reveals that the effects of loss go even deeper: Loss can compromise our early perception and interfere with our grasp of the true situation. The findings, which recently appeared in the Journal of Neuroscience, may also have implications for our understanding of the neurological mechanisms underlying...

Experimental drug and genetic difference both indicate how people deal with fear and stress Researchers at Duke University and the National Institutes of Health have found a way to calm the fears of anxious mice with a drug that alters their brain chemistry. They've also found that human genetic differences related to the same brain chemistry influence how well people cope with fear and stress. It's an advance in understanding the brain's fear circuitry that the research team says may...

The baseline level of distrust is distinct and separable from our inborn lie detector Fool me once, shame on you. Fool me twice, shame on my parahippocampal gyrus. Scientists at the Virginia Tech Carilion Research Institute have found that suspicion resides in two distinct regions of the brain: the amygdala, which plays a central role in processing fear and emotional memories, and the parahippocampal gyrus, which is associated with declarative memory and the recognition of scenes....

Sanford-Burnham researchers discover the molecular basis of autistic symptoms in children with a rare bone disorder -- findings that also provide new insights for the general autistic population Children with multiple hereditary exostoses (MHE), an inherited genetic disease, suffer from multiple growths on their bones that cause pain and disfigurement. But beyond the physical symptoms of this condition, some parents have long observed that their children with MHE also experience...

Findings in animals could lead to new treatments for people suffering from anxiety disorders, including post-traumatic stress disorder Rutgers scientists have uncovered genetic clues as to why some mice no longer in danger are still fearful while others are resilient to traumatic experiences — knowledge that could help those suffering with crippling anxiety and PTSD. "Our work with mice demonstrates how genes play a role in developing and extinguishing pathological fear like Post...

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...

In the classic film "12 Angry Men," Henry Fonda's character sways a jury with his quiet, persistent intelligence. But would he have succeeded if he had allowed himself to fall sway to the social dynamics of that jury? Research led by scientists at the Virginia Tech Carilion Research Institute found that small-group dynamics -- such as jury deliberations, collective bargaining sessions, and cocktail parties -- can alter the expression of IQ in some susceptible people. "You may joke about...

The study, initiated by the Swiss researchers and published in Nature, constitutes ground-breaking work in exploring emotions in the brain. Anxiety disorders constitute a complex family of pathologies affecting about 10% of adults. Patients suffering from such disorders fear certain situations or objects to exaggerated extents totally out of proportion to the real danger they present. The amygdala, a deep-brain structure, plays a key part in processing fear and anxiety. Its functioning can...

Domestic Violence Triggers Brain Changes In Children
2011-12-06 05:23:17

Children exposed to family violence show the same pattern of activity in their brains as soldiers exposed to combat, according to a new study published Monday in the journal Current Biology. The study is the first to use brain scans, or functional magnetic resonance imaging (fMRI), to investigate the impact of physical abuse and domestic violence on children´s emotional development. Scientists at University College London found that exposure to family violence was associated with...
