Rather than count sheep, drink warm milk or listen to soothing music, many insomniacs probably wish for a switch they could flick to put themselves to sleep. Scientists at Washington University School of Medicine in St. Louis have discovered such a switch in the brains of fruit flies. In a study appearing June 24 in Science, the researchers show that a group of approximately 20 cells in the brains of fruit flies controls when and how long the flies sleep. Slumber induced through this sleep...

A protein that helps the brain develop early in life can fight the mental fuzziness induced by sleep deprivation, according to researchers at Washington University School of Medicine in St. Louis. "It's interesting that NOTCH, a protein that plays such a prominent role in development, also has important functions in the adult brain," says senior author Paul Shaw, PhD, associate professor of neurobiology. "To our surprise, we found if NOTCH activity is boosted in the brains of sleep-deprived...

By Michael C. Purdy As anyone who has ever struggled to keep his or her eyes open after a big meal knows, eating can induce sleepiness. New research in fruit flies suggests that, conversely, being hungry may provide a way to stay awake without feeling groggy or mentally challenged. Scientists at Washington University in St. Louis found that starvation allows the need for nourishment to push aside the need for sleep. Like humans and rats, fruit flies cannot survive without sleep. But in a line...

Parkinson's disease is well-known for impairing movement and causing tremors, but many patients also develop other serious problems, including sleep disturbances and significant losses in cognitive function known as dementia. Now researchers at Washington University School of Medicine in St. Louis have modeled Parkinson's-associated dementia for the first time. Scientists showed that a single night of sleep loss in genetically altered fruit flies caused long-lasting disruptions in the flies'...

Researchers at Washington University School of Medicine in St. Louis have created a line of fruit flies that may someday help shed light on the mechanisms that cause insomnia in humans. The flies, which only get a small fraction of the sleep of normal flies, resemble insomniac humans in several ways."Insomnia is a common and debilitating disorder that results in substantial impairments in a person's quality of life, reduces productivity and increases the risk for psychiatric illness," says...
