Latest Prefrontal cortex Stories

In life, many tasks have a context that dictates the right actions, so when people learn to do something new, they'll often infer cues of context and rules. In a new study, Brown University brain scientists took advantage of that tendency to track the emergence of such rule structures in the frontal cortex — even when such structure was not necessary or even helpful to learn — and to predict from EEG readings how people would apply them to learn new tasks speedily. Context and rule...

Keep this in mind: Scientists say they've learned how your brain plucks information out of working memory when you decide to act. Say you're a busy mom trying to wrap up a work call now that you've arrived home. While you converse on your Bluetooth headset, one kid begs for an unspecified snack, another asks where his homework project has gone, and just then an urgent e-mail from your boss buzzes the phone in your purse. During the call's last few minutes these urgent requests — snack,...

Brain Similarities In Humans And Monkeys
2014-01-29 04:46:02

April Flowers for redOrbit.com - Your Universe Online A new study from Oxford University researchers suggests a surprising degree of similarity in the organization of brain regions that control language and complex thought processes in humans and monkeys, as well as key differences. The team's finding demonstrate valuable insights into the evolutionary processes that established the link between humans and other primates and what made humans distinctly different. "We tend to think that...

NEW YORK, Dec. 2, 2013 /PRNewswire-USNewswire/ -- Age-related cognitive decline and changes in the nervous system are closely linked, but up until recently, they were thought to result from the loss of neurons in areas such as the prefrontal cortex, the part of the brain important in working memory. A series of papers have shown that the "loss of neurons" concept is simply not true. Now, Mount Sinai scientists have begun to look elsewhere, focusing instead on synaptic health in the...

A team of researchers at Inserm led by Cyril Herry (Inserm Unit 862, “Neurocentre Magendie,” Bordeaux) has just shown that interneurons located in the forebrain at the level of the prefrontal cortex are heavily involved in the control of fear responses. Using an approach combining in vivo recordings and optogenetic manipulations in mice, the researchers succeeded in showing that the inhibition of parvalbumin-expressing prefrontal interneurons triggers a chain reaction resulting in fear...

Specific area of the brain linked to anxiety disorders in youth Anxiety disorders are common in children and adolescents, affecting up to 25 percent of the youth population. Anxiety causes distress and functional impairment and, if left untreated, can result in bad grades, problems at home and increased rates of psychiatric disorders in adulthood. These risks constitute a significant public health burden, and they underscore the importance of continued efforts to understand the cause...

For want of a receptor: Some behaviors shaped during early development Physical and chemical changes in the brain during development can potentially play a role in some delinquent and deviant behaviors, according to research released today. Studies looking at the underlying mechanisms that influence our ability to exercise self-control were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science...

Trying to explain riding a bike is difficult because it is an implicit memory. The body knows what to do, but thinking about the process can often interfere. So why is it that under certain circumstances paying full attention and trying hard can actually impede performance? A new UC Santa Barbara study, published today in the Journal of Neuroscience, reveals part of the answer. There are two kinds of memory: implicit, a form of long-term memory not requiring conscious thought and expressed...

Self-Control Through Precommitment More Effective Than Willpower
2013-07-25 08:38:14

April Flowers for redOrbit.com - Your Universe Online The key to losing weight, or saving for the future, is avoiding temptation all together, according to a new study from the Universities of Cambridge and Dusseldorf. The study on self-control suggests avoidance is a better strategy than depending on will power alone. The study, published in Neuron, compared the effectiveness of willpower versus voluntarily restricting access to temptations, called 'precommitment'. For example,...

Research could have direct application for treating human drinking problems A research team led by scientists from the Ernest Gallo Clinic and Research Center at the University of California, San Francisco has identified circuitry in the brain that drives compulsive drinking in rats, and likely plays a similar role in humans. The scientists found they could reduce compulsive drinking in rats by inhibiting key neural pathways that run between the prefrontal cortex, which is involved with...
