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...

(Ivanhoe Newswire) -- Why do we sleep?  I mean, we spend so much of our time sleeping that it must be doing something important.  It seems pretty simple right?  Not exactly.  There are myriad theories about rapid eye movement (REM) sleep, however, scientists have spent many sleepless nights determining why we spend so many hours in light, dreamless slumber.  Well, according to a new-fangled study, it is suggested that we are busy recharging our brain's learning...

By Yasmin Anwar, UC Berkeley A UC Berkeley study suggests we're busy recharging our brain's learning capacity during a dreamless light slumber that takes up half our sleeping hours Scientists have long puzzled over the many hours we spend in light, dreamless slumber. But a new study from the University of California, Berkeley, suggests we're busy recharging our brain's learning capacity during this traditionally undervalued phase of sleep, which can take up half the night. UC Berkeley...

A team of sleep scientists led by Dr. Fabio Ferrarelli of the University of Wisconsin-Madison found that during non-rapid eye movement sleep (non-REM, or dreamless sleep), the brain waves produced by people with schizophrenia lack the normal pattern of slow and fast spindles. Madison, Wis. (Vocus) November 23, 2010 When people with schizophrenia sleep, their brain waves show a distinctive pattern that may someday lead to one of the first biological markers for this devastating mental...

Discovery of novel genes and brain areas associated with sleep deprivation may have implications for improved management of brain function Researchers at the Allen Institute for Brain Science and SRI International have published the most systematic study to date of the effects of sleep deprivation on gene expression in the brain. The findings have implications for improving the understanding and management of the adverse effects of sleep deprivation on brain function. The study, available in...

It is one thing to learn a new piece of information, such as a new phone number or a new word, but quite another to get your brain to file it away so it is available when you need it. A new study published in the Journal of Neuroscience by researchers at the University of York and Harvard Medical School suggests that sleep may help to do both. The scientists found that sleep helps people to remember a newly learned word and incorporate new vocabulary into their "mental lexicon". During the...

Presentations focus on the brain and sleep The ability to remember is not just to glimpse into the past; a sharp memory can help with creativity, productivity and even the ability to imagine the future, according to several psychologists. Sleep, aging and brain chemistry research were all discussed during several presentations on memory at the 118th Annual Convention of the American Psychological Association. The benefits of sleep are well-documented, but researcher Sara C. Mednick, PhD, and...
