Misleading statement above - Blood flowing through vessels can cause
brain vessels to rhythmically dilate and constrict. Diastolic and
systolic pressure changes cause this effect.

waves of cleansing fluid

I'd have to read that article, but where is this fluid "manufactured?"

Blood vessels throughout the body can do this, rhythmically dilate and
constrict, while sleeping. Again, I'd have to read the article, but
these researchers seem to be misrepresenting body wide events.
