Genetic mutation found to alter activity of neurons in brain's prefrontal cortex Imagine if your brain lost its working memory "” the ability to hold and manipulate information in your mind's eye. That's the plight faced by millions of people with neurofibromatosis type 1, or NF1. The genetic condition affects one in 3,500 people and is the most common cause of learning disabilities. Now a UCLA research team has uncovered new clues about how NF1 disrupts working memory. Published in the...

Researchers said on Tuesday that brain scans may be able to predict what you will do better than you can yourself, and be a powerful tool for health officials or advertisers seeking to motivate consumers. The researchers found a way to interpret "real time" brain images to show whether people who viewed messages about using sunscreen would actually use the product. Emily Falk and colleagues at the University of California Los Angeles said the scans were more accurate than the volunteers...

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...

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...

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...

Like patients, engineered mice falter at working memory tasks The strongest known recurrent genetic cause of schizophrenia impairs communications between the brain's decision-making and memory hubs, resulting in working memory deficits, according to a study in mice. "For the first time, we have a powerful animal model that shows us how genetics affects brain circuitry, at the level of single neurons, to produce a learning and memory deficit linked to schizophrenia," explained Thomas R. Insel,...

NEW YORK, NY "“ In what may provide the most compelling evidence to date, researchers at Columbia University Medical Center have illuminated how a genetic variant may lead to schizophrenia by causing a disruption in communication between the hippocampus and prefrontal cortex regions of the brain, areas believed to be responsible for carrying out working memory. Findings are published in the current online edition of Nature. This discovery coincides with the 15th anniversary of the first...

New research provides insight into the region of the brain that underlies our tendency to condemn failed attempts to harm and forgive harms that are accidental. The study, published by Cell Press in the March 25 issue of the journal Neuron, underscores the importance of the ventromedial prefrontal cortex (VMPC) for making moral judgments about harmful intent. Previous neuropsychological and neuroimaging studies implicated the VMPC in emotional responses to harmful actions, where the actor...
