and that links to the abstract

#3Can anyone with better knowledge of such things explain why this has to occur during sleep? Is there just too much going on during the day to dedicate physical and mental resources to this type of cleaning?

The question on everyone's mind now is, can you bypass that need?

I wonder if sleepwalkers have this cleanup system working normally just and the part that supposed to shut off the muscles is not working properly.

We'd need some chemical that can cross blood brain barrier, get into the cells and refactor most harmful subtances that build up there. Not an easy task.

That was my understanding of both sleep walking and sleep paralysis. The parts of your brain that activate during REM dreaming would cause you hurt yourself if GABA and glycine didn't shut off your muscles, thus putting your body into the bio-equivalent of park.

Have you tried the new polyphasic garbage collector?
