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...

MU researchers find evidence that there may be developmentally limited forms of bipolar Bipolar disorder, or manic-depression, causes severe and unusual shifts in mood and energy, affecting a person's ability to perform everyday tasks. With symptoms often starting in early adulthood, bipolar disorder has been thought of traditionally as a lifelong disorder.  Now, University of Missouri researchers have found evidence that nearly half of those diagnosed between the ages of 18 and 25 may...

A new study explores how our brains synthesize concepts that allow us to organize and comprehend the world. The research, published by Cell Press in the September 24th issue of the journal Neuron, uses behavioral and neuroimaging techniques to track how conceptual knowledge emerges in the human brain and guides decision making. The ability to use prior knowledge when dealing with new situations is a defining characteristic of human intelligence. This is made possible through the use of...

 If you've ever felt doomed to repeat your mistakes, researchers at MIT's Picower Institute for Learning and Memory may have explained why: Brain cells may only learn from experience when we do something right and not when we fail.In the July 30 issue of the journal Neuron, Earl K. Miller, the Picower Professor of Neuroscience, and MIT colleagues Mark Histed and Anitha Pasupathy have created for the first time a unique snapshot of the learning process that shows how single cells change...
