EMBL scientists discover neural switch that controls fear Fear can make you run, it can make you fight, and it can glue you to the spot. Scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy and GlaxoSmithKline in Verona, Italy, have identified not only the part of the brain but the specific type of neurons that determine how mice react to a frightening stimulus. In a study published today in Neuron, they combined pharmaceutical and genetic approaches with...

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...

New research finds that the brains of overweight people are less sensitive to feelings of hunger when responding to the smell and taste of food, compared to healthy weight individuals Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds that that feelings of hunger have less influence on how the brain responds to the smell and taste of food in...

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 neuropeptide oxytocin makes it easier to feel for other people 48 healthy males participated in the experiment. Half received an oxytocin nose spray at the start of the experiment, the other half a placebo. The researchers then showed their test subjects photos of emotionally charged situations in the form of a crying child, a girl hugging her cat, and a grieving man. The test subjects were then invited to express the depth of feeling they experienced for the persons shown. In summary,...

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...
