Stress response in the brain relies on a blood-thinning protein (11/24/2007)

A stressed-out mouse tends to be a bit timid, tentative, even fearful. For that matter, so does a stressed-out human. Our ability to learn from frightening situations is part of what helps us avoid them in the future. When that learning process goes awry, it can lead to depression and a decreased ability to recognize dangerous situations. Now, research by Rockefeller scientists has pinned down a protein in the hippocampus - a part of the brain that controls memory, learning and fear - that's essential for maintaining this stress response. ...> Full Article

Neurological Team Finds that New Treatment Holds Promise for Patients with Tourette Syndrome (11/17/2007)

Research out of the Neurological Institute at University Hospitals Case Medical Center finds that Deep Brain Stimulation (DBS) helps patients who suffer from Tourette Syndrome (TS). This first-of-its-kind study of five adults with TS determined that DBS can reduce tic frequency and severity in some people who have exhausted other medical treatments. ...> Full Article

Brain Matures a Few Years Late in ADHD, But Follows Normal Pattern (11/17/2007)

In youth with attention deficit hyperactivity disorder (ADHD), the brain matures in a normal pattern but is delayed three years in some regions, on average, compared to youth without the disorder, an imaging study by researchers at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) has revealed. The delay in ADHD was most prominent in regions at the front of the brain's outer mantle (cortex), important for the ability to control thinking, attention and planning. Otherwise, both groups showed a similar back-to-front wave of brain maturation with different areas peaking in thickness at different times (see movie below). ...> Full Article

Early Teen Sex May Not Be a Path to Delinquency, Study Shows (11/15/2007)

A new study by University of Virginia clinical psychologists has found that teens who have sex at an early age may be less inclined to exhibit delinquent behavior in early adulthood than their peers who waited until they were older to have sex. The study also suggests that early sex may play a role in helping these teens develop better social relationships in early adulthood. ...> Full Article

Research team finds link between asthma and depressive and anxiety disorders (11/13/2007)

Young people with asthma are about twice as likely to suffer from depressive and anxiety disorders than are children without asthma, according to a study by a research team in Seattle. Previous research had suggested a possible link in young people between asthma and some mental health problems, such as panic disorder, but this study is the first showing such a strong connection between the respiratory condition and depressive and anxiety disorders. The findings appear in the November issue of the Journal of Adolescent Health. ...> Full Article

How The Brain Sends Eyeballs Bouncing (11/13/2007)

All vision, including reading this sentence, depends on a constant series of infinitesimal jumps by the eyeball that centers the retina on target objects--words or phrases in the case of reading. Such jumps, or saccades, are critical to vision because only the small central region of the retina, called the fovea, produces the clear image necessary for perception. Such saccades take place several times a second and are generated within a brain region known as the frontal eye field (FEF). ...> Full Article
