These slow, rhythmic blasts, described for the first time in the Nov. 1 Science, may help explain why sleep is so important for brain health. Studies on animals have shown that the fluid, called CSF, can wash harmful proteins, including those implicated in Alzheimer’s disease, out of the brain. The new results give heft to the idea that a similar power wash happens in sleeping people.
I wonder if it helps the spin cycle? I have issues with vertigo when I sleep or move my head too fast.
When it comes to some of the BPS researchers and their allies, I think the problem is more one of an "unbalanced load."
