A new study uses optogenetics to induce localized sleep in awake mice, reversing memory loss from sleep deprivation.

Mice seemed to reap some of the benefits of sleep by having their brain activity stimulated while they were awake, and the ...

By inducing specific patterns of activity in small portions of the brain in awake mice, researchers supported by the National Institutes of Health (NIH) have triggered a recalibration of neural ...

Nothing soothes the soul like a deep sleep. We all know the feeling: eyelids that refuse to stay open, a yawning mouth that refuses to stay closed, and a scattered mind that refuses to stay focused.

During sleep, the brain weakens the new connections between neurons that had been forged while awake -- but only during the first half of a night's sleep, according to a new study. During sleep, the ...

People with breathing problems during sleep may have a larger hippocampus, the area of the brain responsible for memory and thinking, according to a new study. The study, which included mostly Latino ...

These effects are based on brain plasticity — the brain’s ability to reshape itself in response to experiences and learning.

A machine-learning analysis of brain waves recorded during sleep may help identify people at high risk of developing dementia, according to a study led by UC San Francisco and Beth Israel Deaconess ...

Sleep helps the brain to cleanse itself—and now this process can be measured in humans entirely noninvasively. Researchers at the University of Oulu have developed a method that allows the increased ...

We know quality sleep is good for our overall health, but new research is pointing to its importance for brain health too. In the study, published Wednesday in online journal Neurology, researchers ...

Researchers studied a group of adults to learn more about the connection between sleep quality and brain aging. The scientists used MRI scans to determine each person’s ‘brain age’ and compared that ...
