New research provides fascinating insight into mechanisms that underlie recovery after damage to a region of the brain important for memory and attention. The research, published by Cell Press in the November 4th issue of the journal Neuron, highlights the role of undamaged portions of the brain that can "take over" and support the recovery of function. Brain damage can have devastating consequences, depending on the location and severity of the injury. Damage to an area of the brain called...

'Phantom' images our brain keeps for visual comparisons stored in brain's neural network Brain research over the past 30 years has shown that if a part of the brain controlling movement or sensation or language is lost because of a stroke or injury, other parts of the brain can take over the lost function "“ often as well as the region that was lost. New research at the University of California, Berkeley, shows that this holds true for memory and attention as well, though "“ at...

People's brains are more responsive to friends than to strangers, even if the stranger has more in common, according to a study in the Oct. 13 issue of The Journal of Neuroscience. Researchers examined a brain region known to be involved in processing social information, and the results suggest that social alliances outweigh shared interests. In a study led by graduate student Fenna Krienen and senior author Randy Buckner, PhD, of Harvard University, researchers investigated how the medial...

Researchers at the University of Illinois at Chicago are the first to use brain imaging to examine the effects of emotion on working memory function in children with pediatric bipolar disorder or attention deficit hyperactivity disorder. The study is published in the October issue of the Journal of the American Academy of Child & Adolescent Psychiatry. PBD and ADHD are very severe developmental disorders that share behavioral characteristics such as impulsivity, irritability and attention...

University of Colorado scientists study seriously troubled teens Antisocial boys who abuse drugs, break laws, and act recklessly are not just "bad" kids. Many of these boys may have malfunctioning brains, according to a new study by researchers at the University of Colorado School of Medicine. "Brain responses to everyday rewards and punishments gradually guide most youngsters' decisions to conform with society's rules. However, when these seriously troubled kids experience rewards and...

Narcissists spend their resting time deep in thought, a new imaging study shows, though such reflection likely revolves entirely around the thinker. USC neuroscientists found a correlation between high scores on a measure of narcissism - the Machiavellian Egocentricity subscale - and activity during rest in the posteromedial cortex, a brain region that previous studies have associated with thoughts about the self. The finding, published online by PLoS ONE, does more than bolster a stereotype....

Structure of prefrontal cortex helps humans think about one's own thinking A specific region of the brain appears to be larger in individuals who are good at turning their thoughts inward and reflecting upon their decisions, according to new research published in the journal Science. This act of introspection"”or "thinking about your thinking""”is a key aspect of human consciousness, though scientists have noted plenty of variation in peoples' abilities to introspect. The new...

A new University of Colorado at Boulder study sheds light on the brain mechanisms that allow us to make choices and ultimately could be helpful in improving treatments for the millions of people who suffer from the effects of anxiety disorders. In the study, CU-Boulder psychology Professor Yuko Munakata and her research colleagues found that "neural inhibition," a process that occurs when one nerve cell suppresses activity in another, is a critical aspect in our ability to make choices. "The...

Humans and other animals use this circuitry to make basic decisions about things like food, discounting the involvement of a specific 'moral sense' Scientists at Harvard University have found that humans can make difficult moral decisions using the same brain circuits as those used in more mundane choices related to money and food. These circuits, also found in other animals, put together two critical pieces of information: How good or bad are the things that might happen? What are the odds...

Kerry Ressler's research on the molecular biology of fear could lead to better methods for treating individuals suffering from anxiety disordersKerry Ressler wants to understand the molecular biology of fear."We're studying how the biology of the brain is changed by the environment, and how these changes underlie memories and experiences," said Ressler, an associate professor in the department of psychiatry and behavioral sciences at Emory University School of Medicine and Yerkes National...
