A popular hypothesis for how the brain clears molecular waste, which may help explain why sleep feels refreshing, is a subject of debate. Encased in the skull, perched atop the spine, the brain has a ...

Researchers report that the flow of cerebrospinal fluid in the brain is linked to waking brain activity. The study demonstrates that manipulating blood flow in the brain with visual stimulation ...

Researchers have discovered a new way to help liquid flow in only one direction, but without using the flaps that engines and our circulatory system rely upon to prevent fluid backup. The team created ...

Waves of cerebrospinal fluid which normally wash over brains during sleep can be made to pulse in the brains of people who are wide awake, a new study finds. The clear fluid may flush out harmful ...
