A new UC Berkeley study shows that sleep deprivation dulls our ability to accurately read facial expressions. This deficit can have serious consequences, such as not noticing that a child is sick or in pain, or that a potential mugger or violent predator is approaching.

Sleep may be a missing piece of the Alzheimer’s puzzle. The toxic protein that is the hallmark of Alzheimer’s disease blocks the deepest stages of sleep, resulting in memory decline, according to new research.

We spend one-third of our lives sleeping, and yet it is only in the last decade or so that scientists have begun to really understand why. 

UC Berkeley researchers have found that a lack of sleep, which is common in anxiety disorders, may play a key role in ramping up the brain regions that contribute to excessive worrying.

The connection between poor sleep, memory loss and brain deterioration as we grow older has been elusive.  But for the first time, scientists at the University of California, Berkeley, have found a link between these hallmark maladies of old age. Their discovery opens the door to boosting the quality of sleep in elderly people to improve memory.

Two new studies by researchers at UC Berkeley’s Sleep and Neuroimaging Laboratory unveil further evidence about the dangers of too little sleep.

They say time heals all wounds, and new research from UC Berkeley indicates that time spent in dream sleep can help. UC Berkeley researchers have found that during the dream phase of sleep, also known as REM sleep, our stress chemistry shuts down and the brain processes emotional experiences and takes the painful edge off difficult memories.

Catching z’s can seem overrated when school is demanding, your body is young, and you’re newly on your own. Students, researchers, and health care providers grapple with the whys and hows of sleep.

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 UC Berkeley.

Scientists have long puzzled over the many hours we spend in light, dreamless slumber. But a new study from UC 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.

In the midst of forecasts of continuing economic woes and congressional gridlock, experts gathered recently at UC Berkeley to assess what worked and what didn’t during the Great Depression-inspired New Deal, the Obama administration’s still emerging efforts to ease the Great Recession, and prospects for relief, reform and recovery.

If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don’t roll your eyes. New research from UC Berkeley shows that an hour’s nap can dramatically boost and restore your brainpower. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter.
