New study suggests "glymphatic system" flushes brain of toxins during sleep

A new study published in the journal Science on Thursday and reported in the Washington Post suggests that a so-called "glymphatic system" seems capable of flushing toxins (including perhaps beta-amyloid) from brain -- particularly during sleep.“Sleep puts the brain in another state where we clean out all the byproducts of activity during the daytime,” said study author and University of Rochester neurosurgeon Maiken Nedergaard.
