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...

Personalities come in all kinds. Now psychological scientists have found that the size of different parts of people's brains correspond to their personalities; for example, conscientious people tend to have a bigger lateral prefrontal cortex, a region of the brain involved in planning and controlling behavior. Psychologists have worked out that all personality traits can be divided into five factors, commonly called the Big Five: conscientiousness, extraversion, neuroticism, agreeableness,...

Researchers of the University of Granada have demonstrated that patients who have damage to the right prefrontal cortex of the brain present a deficit in intentional anticipation (for example, when we put the vehicle in gear before the traffic light turns green). The findings of this study were published in the prestigious journal Brain. Researchers of the University of Granada have demonstrated that patients who have damage to the right prefrontal cortex of the brain "“the part...

Sex "addiction" is a concept that has had particularly high visibility recently with the publicity associated with Tiger Woods. Persons with addictive or compulsive disorders frequently display an inability to inhibit behaviors once they become maladaptive, despite adverse consequences of their behavior. The medial prefrontal cortex (mPFC) is a brain region involved in decision-making and behavioral flexibility, and it has been identified as a potential mediator of behavioral inhibition. In a...

LONDON, May 11, 2010 /PRNewswire/ -- The subject of extensive studies across the world, Resveratrol is proving to be a major talking point in the scientific community. And as evidence comes to light of the continuing beneficial effects of this compound, a further study by the University of Northumbria in the UK has confirmed what many scientists already believe to be the case - that Resveratrol could have a significant impact on the cognitive processes of the human brain. The...

The ability to infer what another person is thinking is an essential tool for social interaction and is known by neuroscientists as "Theory of Mind" (ToM), but how does the brain actually allow us to do this? We are able to rationally infer what someone knows, thinks, or intends, but we are also able to "slip into their shoes" and infer how they feel, and it seems that the brain processes these different types of information in different ways, as confirmed by a new report in the June 2010...

New research by David Badre, assistant professor of cognitive and linguistic sciences at Brown University, and colleagues at the University of California"“Berkeley suggests that the frontal cortex may have a larger role in decision-making in unfamiliar situations. Their paper appears in the current edition of Neuron. Scientists have long known that the brain's frontal cortex supports concrete rule learning. Less clear is how the brain processes more complex and unfamiliar knowledge. In...

New study links psychopathy to frontal lobe dysfunction Psychopaths are known to be characterized by callousness, diminished capacity for remorse, and lack of empathy. However, the exact cause of these personality traits is an area of scientific debate. The results of a new study, reported in the May 2010 issue of Elsevier's Cortex, show striking similarities between the mental impairments observed in psychopaths and those seen in patients with frontal lobe damage. One previous explanation...

Brain scans show persistent motivation regardless of payoff Whether it's for money, marbles or chalk, the brains of reward-driven people keep their game faces on, helping them win at every step of the way. Surprisingly, they win most often when there is no reward. That's the finding of neuroscientists at Washington University in St. Louis, who tested 31 randomly selected subjects with word games, some of which had monetary rewards of either 25 or 75 cents per correct answer, others of which...

CHAMPAIGN, Ill. "” A new study of brain activity in depressed and anxious people indicates that some of the ill effects of depression are modified "“ for better or for worse "“ by anxiety. The study, in the journal Cognitive, Affective & Behavioral Neuroscience, looked at depression and two types of anxiety: anxious arousal, the fearful vigilance that sometimes turns into panic; and anxious apprehension, better known as worry. The researchers used functional Magnetic...
