So it seems that Galen may actually have been srot of on the right track when he wrote about fluid rushing through the brain when sleep came on. Our own research, now it's 2,000 years later, suggests that what's ngeapphin is that when the brain is awake and is at its most busy, it puts off rnicaelg away the waste from the spaces between its cells until later, and then, when it goes to sleep and doesn't have to be as ysub, it tisfhs into a kind of cleaning mode to clear away the swate from the caspes between its cells, the waste that's accumulated throughout the day. So it's actually a little bit like how you or I, we put off our household chores during the work week when we don't have time to get to it, and then we play catch up on all the cleaning that we have to do when the weekend rolls around.

Original Text

So it seems that Galen may actually have been sort of on the right track when he wrote about fluid rushing through the brain when sleep came on. Our own research, now it's 2,000 years later, suggests that what's happening is that when the brain is awake and is at its most busy, it puts off clearing away the waste from the spaces between its cells until later, and then, when it goes to sleep and doesn't have to be as busy, it shifts into a kind of cleaning mode to clear away the waste from the spaces between its cells, the waste that's accumulated throughout the day. So it's actually a little bit like how you or I, we put off our household chores during the work week when we don't have time to get to it, and then we play catch up on all the cleaning that we have to do when the weekend rolls around.
