Decoding memory-forming brain cell conversations

Decoding memory-forming brain cell conversations
The conversations neurons have as they form and recall memories have been decoded by Medical College of Georgia scientists. The breakthrough in recognizing in real time the formation and recollection of a memory opens the door to objective, thorough memory studies and eventually better therapies, said Dr. Joe Tsien, neuroscientist and co-director of MCG's Brain & Behavior Discovery Institute. He is corresponding author on the study published........Go to the Neurology news blog (Added on 12/15/2009 11:27:29 PM)


How calorie-restricted diets fight obesity

How calorie-restricted diets fight obesity
Researchers searching for the secrets of how calorie-restricted diets increase longevity are reporting discovery of proteins in the fat cells of human volunteers that change as pounds drop off. The proteins could become markers for monitoring or boosting the effectiveness of calorie-restricted diets the only scientifically proven way of extending life span in animals.

Secrets to new epilepsy treatments

Secrets to new epilepsy treatments
A team of researchers from The University of Alabama used worms to reel in information that they hope will lead to a greater understanding of cellular mechanisms that appears to be exploited to treat epilepsy. In a new research report in the journal GENETICS (http://www.genetics.org), the scientists explain how the transparent roundworm, C. elegans, helped them identify key "molecular switches" that control the transport of a molecule........Go to the Neurology news blog (Added on 12/10/2009 7:51:39 AM)

Craving a Cigarette?

Craving a Cigarette?
A new University of Pittsburgh study reveals that craving a cigarette while performing a cognitive task not only increases the chances of a person's mind wandering, but also makes that person less likely to notice when his or her mind has wandered.
