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.
Náš vlastní výzkum o 2000 let později naznačuje, že když je mozek vzhůru a je na vrcholu své aktivity, odkládá čištění odpadu z prostoru mezi svými buňkami na později. A potom, když jdeme spát a mozková aktivita poklesne, přepne se do "úklidového režimu", aby mezi svými buňkami uklidil odpad, který se tam nahromadil v průběhu dne.
