Individuals with major depressive disorder (MDD) often undergo multiple courses of antidepressant treatment during their lives. This is because the disorder can recur despite treatment and because finding the right medication for a specific individual can take time. While the relationship between prior treatment and the brain's response to subsequent treatment is unknown, a new study by UCLA researchers suggests that how the brain responds to antidepressant medication may be influenced by...

(Ivanhoe Newswire) — Autism is a highly heritable neurodevelopmental disorder, yet the genetic underpinnings in the brain at young ages have remained largely unknown. But for the first time, researchers have identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder Until now, few studies have been able to investigate whole-genome gene expression and genotype variation in the brains of young patients...

Genetic studies find dysregulation in pathways that govern development of the prefrontal cortex in young patients with autism A study led by Eric Courchesne, PhD, director of the Autism Center of Excellence at the University of California, San Diego School of Medicine has, for the first time, identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder. The findings suggest novel genetic and molecular targets...

(Ivanhoe Newswire) -- My toy, my snack, my juice box, kids can be selfish! A new study suggests that age-associated improvements in the ability to consider others are linked with maturation of the brain region involved in self control. The study may help to explain why children can be selfish when they are taught better and could improve educational strategies that are designed to encourage successful social behavior. Social interactions involve two parties who want the greatest possible...

(Ivanhoe Newswire) — Stress is a term commonly used today, and we know it can have an impact on one´s mental and physical well-being. Now researchers are saying it may affect your memory too! New research out of State University in New York, uncovered a neural mechanism that directly links repeated stress with impaired memory. Stress hormones are known to influence the prefrontal cortex (PFC), a brain region that controls high level "executive" functions such as working memory...

Neuron paper by UB researchers reveals why chronic stress in adolescence impairs memory, may trigger mental illness Chronic stress has a more powerful effect on the brain during adolescence than in adulthood and now there's proof at the molecular level. "We have identified a causal link between molecules and behaviors involved in stress responses," says Zhen Yan, PhD, a professor in the Department of Physiology and Biophysics in the UB School of Medicine and Biomedical Sciences. "It's...

A new study suggests that age-associated improvements in the ability to consider the preferences of others are linked with maturation of a brain region involved in self control. The findings may help to explain why young children often struggle to control selfish impulses, even when they know better, and could impact educational strategies designed to promote successful social behavior. Human social interactions often involve two parties who want to maximize their own outcomes while...

UCSF Study Shows Digital Cognitive Training Improves Brain Function and Behavior for People with Schizophrenia People with schizophrenia who completed 80 hours of intensive, computerized cognitive training exercises were better able to perform complex tasks that required them to distinguish their internal thoughts from reality. As described in the journal Neuron on Feb. 22, 2012, a small clinical study conducted at the San Francisco VA Medical Center (SFVAMC) and the University of...

It´s Valentine´s Day, he forgot to bring flowers, and somehow that painfully sad look on her face is simply not registering in his mind.  Could be it´s a problem in his prefrontal cortex? Neuropsychology researchers at the Montreal Neurological Institute and Hospital — The Neuro, McGill University, have found that two areas of the prefrontal cortex (PFC) are critical for either detecting or distinguishing emotions from facial expressions.  People with damage...
