First images of cerebrospinal fluid in the brain during sleep (2019)
A new study from Boston University is the first to illustrate that the brain’s cerebrospinal fluid pulses during sleep, and that these motions are closely tied with brain wave activity and blood flow. It may confirm the hypothesis that CSF flow and slow-wave activity both help flush toxic, memory-impairing proteins…
