By studying young monkeys, scientists from the University of Wisconsin-Madison School of Medicine and Public Health believe they have found the areas of the brain that cause childhood anxiety. The study, which was published in the August 12 edition of Nature, could potentially help doctors develop new methods for detecting and treating kids at-risk for developing anxiety-related disorders, according to a press release published by the university on Wednesday. Young primates who had increased...

UCLA research has implications for recovery from brain injuries Many neuroscientists believe the loss of the brain region known as the amygdala would result in the brain's inability to form new memories with emotional content. New UCLA research indicates this is not so and suggests that when one brain region is damaged, other regions can compensate. The research appears this week in the early online edition of the journal Proceedings of the National Academy of Sciences (PNAS). "Our findings...

Researchers at India's National Centre for Biological Sciences (NCBS) and New York University's Center for Neural Science have identified novel synaptic defects in an area of the brain that is involved in the debilitating emotional symptoms of Fragile X Syndrome (FXS). FXS is the leading known genetic cause of autism and mental retardation. The study, which appears in the journal the Proceedings of the National Academy of Sciences, is also of potential therapeutic significance"”it...

Fish become feisty but fearful when facing themselves in a mirror, according to two Stanford biologists. "It seems like something they don't understand," said Julie Desjardins, a post-doctoral researcher in biology and lead author of a paper to be published in Biology Letters describing the study. The paper is available online now. "I think this stimulus is just so far outside their realm of experience that it results in this somewhat emotional response." Desjardins and coauthor Russell...

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...

People with generalized anxiety disorder, or GAD, have abnormalities in the way their brain unconsciously controls emotions. That's the conclusion of a new Stanford University School of Medicine study, and the study authors say the findings could open up new avenues for treatments and change our understanding of how emotion is regulated in everyday life. The work is published online in this month's American Journal of Psychiatry. According to the National Institute of Mental Health, 18...

Two patients with rare lesions to the brain have provided direct of evidence of how we make decisions "“ and what makes us dislike the thought of losing money. Researchers at the California Institute of Technology studied a phenomenon known as 'loss aversion' in two patients with lesions to the amygdala, a region deep within the brain involved in emotions and decision-making. The results of the study, part-funded by the Wellcome Trust, are published today in the journal Proceedings of...

Neuroscientists at the California Institute of Technology (Caltech) and their colleagues have tied the human aversion to losing money to a specific structure in the brain"“the amygdala. The finding, described in the latest online issue of the journal Proceedings of the National Academy of Sciences (PNAS), offers insight into economic behavior, and also into the role of the brain's amygdalae, two almond-shaped clusters of tissue located in the medial temporal lobes. The amygdala...
