Your sleeping brain is not quiet. Electrical waves roll across it, blood vessels rhythmically change size and cerebrospinal ...

A barely noticeable sound delivered at exactly the right moment during sleep may give one of the brain’s overnight maintenance systems a boost. MIT researchers found that precisely timed bursts of ...

Think pink for better sleep and extra brain benefits. While research is mixed about the benefits of background noise during ...

Carefully timed sounds can make fluid waves larger in the sleeping brain, giving researchers a new way to study how brain activity and CSF flow are connected.

During the day, waste products such as lactic acid and worn-out proteins build up in the brain. When we sleep at night, waves ...

During sleep, the brain cleans itself, turning up the flow of cerebrospinal fluid through the gray matter parenchyma to wash away waste. What powers this flow? In the February 28 Nature online, ...

Researchers have known that a lack of quality sleep can increase a person’s risk of diabetes, but it’s not been known why. The results of a study in humans by a team of sleep scientists at the ...

Researchers have known that a lack of quality sleep can increase a person's risk of diabetes. What has remained a mystery, however, is why. Now, new findings from a team of sleep scientists at the ...

Forget counting sheep. Across the country, roughly one in three American adults get less than the recommended seven hours of ...
