The brain's cerebrospinal fluid (CSF) pulses during deep sleep and this appears to be tied to brain wave activity and blood flow, an exploratory study showed. Large oscillations of CSF inflow to ...

A few seconds later, blood will flow out of your head. Then, a watery liquid called cerebrospinal fluid (CSF) will flow in, washing through your brain in rhythmic, pulsing waves.

To trace this cerebral plumbing, first authors Hokyung Jin, Jin-Hui Yoon, Seon Pyo Hong, and colleagues turned to the well-established Prox1-GFP mice, whose lymphatic vessels glow green under the ...

Key points During sleep, brain waste products are cleared from the brain through enhanced flow of Cerebrospinal Fluid (CSF). Removal of such waste, including beta amyloid and tau protein, is ...

Relative to controls, CSF average net flow in HD was about half, and in later stages it was only about 13%. The finding may bear implications for disease progression and treatment, the authors write.

This has spurred scientists to wonder whether enhancing the flow of CSF could boost brain health. But lymphatic vessels that drain CSF have previously only been identified deep in the neck, making ...
