Brain Drains Toxins During Sleep
(Ivanhoe Newswire) – While we sleep, the space between brain cells expands by 60 percent, allowing toxins built up throughout the day to drain out, according to new research.
The study, performed by researchers at the University of Rochester, in New York, used electrodes to examine the space between brain cells during sleep. Researchers found this space helps fluid move more easily through the glymphatic system, which acts as a plumbing system for the brain.
"Sleep changes the cellular structure of the brain. It appears to be a completely different state," study lead Maiken Nedergaard, MD, was quoted as saying. "We need sleep. It cleans up the brain.”
