Reading this story requires you to willfully pay attention to the sentences and to tune out nearby conversations, the radio and other distractions. But if a fire alarm sounded, your attention would be involuntarily snatched away from the story to the blaring sound. New research from Vanderbilt University reveals for the first time how our brains coordinate these two types of attention and why we may be temporarily blinded by surprises. The research was published March 7, 2010, in Nature...

Activity in the lateral prefrontal cortex is an indicator emotion regulation in day-to-day life Common wisdom tells us that for a successful relationship partners shouldn't go to bed angry. But new research from a psychologist at Harvard University suggests that brain activity"”specifically in the region called the lateral prefrontal cortex"”is a far better indicator of how someone will feel in the days following a fight with his or her partner. Individuals who show more neural...

Brain images during money-transfer experiments show "rich" participants prefer to see others get financial windfall The human brain is a big believer in equality"”and a team of scientists from the California Institute of Technology (Caltech) and Trinity College in Dublin, Ireland, has become the first to gather the images to prove it. Specifically, the team found that the reward centers in the human brain respond more strongly when a poor person receives a financial reward than when a...

Draw a map of the brain when fear and anxiety are involved, and the amygdala"”the brain's almond-shaped center for panic and fight-or-flight responses"”looms large. But the amygdala doesn't do its job alone. Scientists at Emory University have recently built upon work from others, extending the fear map to part of the brain known as the prelimbic cortex. Researchers led by Kerry Ressler, MD, PhD, found that mice lacking a critical growth factor in the prelimbic cortex have trouble...

A new brain-based computational model is helping to understand how Parkinson's disease and dopamine medications"”used to treat motor symptoms caused by the disease"” can affect learning and attention. As reported in a forthcoming article in the Journal of Cognitive Neuroscience, http://www.mitpressjournals.org/doi/pdf/10.1162/jocn.2010.21420, a new computational model, developed by Drs. Ahmed Moustafa and Mark Gluck, at the Center for Molecular and Behavioral Neuroscience at...

Separating the stress from the trauma After exposure to extreme life stresses, what distinguishes the individuals who do and do not develop posttraumatic stress disorder (PTSD)? A new study, published in the October 1st issue of Biological Psychiatry, suggests that it has something to do with the way that we control the activity of the prefrontal cortex, a brain region thought to orchestrate our thoughts and actions. Researchers at the Mount Sinai School of Medicine examined women who had...

Populations of neurons code time with extreme precision in the primate brain What's new: MIT researchers have identified populations of neurons that code time with extreme precision in the primate brain. These neurons are found in two interconnected brain regions, the prefrontal cortex and the striatum, both of which are known to play critical roles in learning, movement, and thought control. Why it matters: The timing of individual actions, whether we are speaking, driving a car, or playing...

Researchers at Medical University of South Carolina (MUSC) pioneer bilateral epidural prefrontal cortical stimulation A new neurosurgical procedure may prove helpful for patients with treatment-resistant depression. Bilateral epidural prefrontal cortical stimulation (EpCS) was found generally safe and provided significant improvement of depressive symptoms in a small group of patients, according to lead researcher Ziad Nahas, M.D. at the Medical University of South Carolina. The data are...

Half of young patients may outgrow bipolar disorder by age 30, U.S. researchers suggest. The Missouri University study, published in the Journal of Abnormal Psychology, was based on two large national surveys. Study co-author Kenneth Sher and colleagues say 5.5 percent to 6.2 percent of people between the ages of 18-24 suffer from bipolar disorder, but only about 3 percent of people older than 29 do. Young adults between the ages of 18-24 are going through significant life changes and social...
