Yet in the same animal, if we wait just a little while until it's gone to sleep, what we see is that the CSF is rushing through the brain, and we discovered that at the same time when the brain goes to sleep, the brain cells themselves seem to shrink, opening up spaces in between them, allowing fluid to rush through and allowing waste to be cleared out.
Mais no mesmo animal, se agardamos un pouco a que adormeza, vemos o LCR circular polo cerebro, e descubrimos que no mesmo momento en que o cerebro comeza a durmir, as neuronas semellan encoller, abrindo espazos entre elas e permitindo que o líquido penetre e limpe os residuos.
