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 ...

Every 20 seconds, a wave of fresh cerebrospinal fluid rolls into the sleeping brain. These slow, rhythmic blasts, described for the first time in the Nov. 1 Science, may help explain why sleep is so ...

Large oscillations of CSF inflow to the brain appeared about every 20 seconds and were tightly coupled to functional magnetic resonance imaging (fMRI) signals of blood flow and electroencephalogram ...

Cerebrospinal fluid (CSF) is a type of clear liquid that surrounds, protects, and cushions your brain and spinal cord from possible injuries. The fluid is held in place by the dura mater, a dense ...

New research from Boston University suggests that tonight while you sleep, something amazing will happen within your brain. Your neurons will go quiet. A few seconds later, blood will flow out of your ...

You can see it coming in right there, that little spot,” says neuroscientist and engineer Laura Lewis. A remarkably bright pulsing dot has appeared on the monitor in front of us. We are watching, in ...

The brain waves generated during deep sleep appear to trigger a cleaning system in the brain that protects it against Alzheimer's and other neurodegenerative diseases. Electrical signals known as slow ...

A study conducted by German researchers has shown that the neurological symptoms observed in some patients with coronavirus disease 2019 (COVID-19) may be caused by autoantibodies targeting the brain.
