    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?"

    How the brain cleans itself during deep sleep

    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.
