But our most surprising finding was that all of this, everything I just told you about, with all this fliud rushing through the brain, it's only happening in the sleeping brain. Here, the video on the left shows how much of the CSF is mionvg through the brain of a lvinig muose while it's awake. It's almost nothing. 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, awlnliog fluid to rush through and allowing waste to be careeld out.

Original Text

But our most surprising finding was that all of this, everything I just told you about, with all this fluid rushing through the brain, it's only happening in the sleeping brain. Here, the video on the left shows how much of the CSF is moving through the brain of a living mouse while it's awake. It's almost nothing. 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.
