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...

A new study suggests that parts of the brain can actually fall asleep for a fraction of a second when tired, despite the fact that the organ as a whole is awake at the time. The implications of the study, which was conducted on rats, are far-reaching, particularly for people performing tasks where sleep deprivation could be dangerous, the scientists said. "Even before you feel fatigued, there are signs in the brain that you should stop certain activities that may require alertness," said...

WASHINGTON, April 12, 2011 /PRNewswire-USNewswire/ -- Torture. The United Nations defines it as the "infliction of severe physical or mental pain or suffering." But how severe is severe? That judgment determines whether or not the law classifies an interrogation practice as torture. Now, a study published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, condemns this method of classification as essentially flawed. The reason: the...

By Yasmin Anwar, University of California, Berkeley A sleepless night can make us cranky and moody. But a lesser known side effect of sleep deprivation is short-term euphoria, which can potentially lead to poor judgment and addictive behavior, according to new research from the University of California, Berkeley. Researchers at UC Berkeley and Harvard Medical School studied the brains of healthy young adults and found that their pleasure circuitry got a big boost after a missed night's sleep....

(Ivanhoe Newswire)"” From overworked professionals to over-extended students, everyone worries about how much sleep they're getting. A new study from Duke University has shown yet another consequence of not sleeping enough: sleep deprivation can lead to a more optimistic outlook, resulting in riskier decisions. Using a functional MRI, scientists showed that a lack of sleep increases brain activity in the brain regions that assess positive outcomes while decreasing activity in the...

The powers that be in Las Vegas figured out something long before neuroscientists at two Duke University medical schools confirmed their ideas this week: Trying to make decisions while sleep-deprived can lead to a case of optimism. The scientists showed, using a functional MRI, that a night of sleep deprivation leads to increased brain activity in brain regions that assess positive outcomes, while at the same time this deprivation leads to decreased activation in the brain areas that process...
