english: 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.
non_english: Ali ako malo sačekamo da životinja zaspi vidimo kako CSF teče kroz mozak, a istovremeno se vidi da se ćelije smanjuju dok mozak spava, čime stvaraju međućelijski prostor i omogućavaju da tečnost prođe i ukloni otpad.
