To see whether massaging these vessels could boost CSF flow, the researchers built a device with a small rod attached to a 1-centimetre-wide cotton ball.

When the pattern was shown, this caused a rise in blood flow to the brain’s visual centres, as expected. When the screen went dark, blood flow reduced and CSF flow into the brain increased.

Earlier studies have suggested that CSF flow and slow-wave activity both help flush toxic, memory-impairing proteins from the brain. As people age, their brains often generate fewer slow waves.

The study - published in Science - is the first to illustrate that the brain’s CSF pulses during sleep, and that these motions are closely tied with brain wave activity and blood flow.

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 ...

New research from Vanderbilt University Medical Center finds that cerebrospinal fluid (CSF) net flow is markedly decreased in Huntington's disease (HD), with the decrease being greater in later ...

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.

In mice, the perivascular pia houses macrophages, perhaps helping them surveil the CSF. It thins as mice age, allowing CSF surrounding the meninges to seep into brain tissue. In amyloidosis mice, the ...
