Using new approaches, an interdisciplinary team of scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center in New York City has gained a view of activity in key brain areas associated with a core difficulty in patients with borderline personality disorder-shedding new light on this serious psychiatric condition.

The Internet is not the fountain of all knowledge, despite the plethora of information available at your fingertips.

The use of cognitive-enhancing drugs by ill as well as healthy individuals is the subject of a commentary published this week in Nature.

Humor appears to develop from aggression caused by male hormones, according to a study published in the Christmas issue of the British Medical Journal.

A new study of combat-exposed Vietnam War veterans shows that those with injuries to certain parts of the brain were less likely to develop post-traumatic stress disorder (PTSD). The findings, from the National Institutes of Health (NIH) and the National Naval Medical Center, suggest that drugs or pacemaker-like devices aimed at dampening activity in these brain regions might be effective treatments for PTSD.

Scientists have found that individual neurons have more computational power and contribute more to behavior than previously thought. The researchers used light to activate individual neurons in living mice and showed that even short bursts of activity in a few neurons can influence learning and decision making.

A brain chemical that makes us sleepy also appears to play a central role in the success of deep brain stimulation to ease symptoms in patients with Parkinson's disease and other brain disorders. The surprising finding is outlined in a paper published online Dec. 23 in Nature Medicine.

When fruit flies lack a receptor for the inhibitory neurotransmitter gamma aminobutyric acid, their ability to learn or remember is enhanced, the first time scientists have been able to induce this effect in the insects, said Baylor College of Medicine researchers in a report that appears today in the journal Neuron.

At its core, healthy neurological function hinges on the efficient passage of information between brain cells via the synapse.
