New research reveals yawning does more than signal tiredness. Scientists observed that yawning causes cerebrospinal fluid to ...

Pulsatile CSF flow dynamics increase during epochs with slower reaction times and attentional failures. (CREDIT: Nature) By 10 a.m., having had no sleep, subjects were lying in MRI scanners engaging ...

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 the ...

Research headed by teams at the University of Rochester Center for Translational Medicine and the University of Copenhagen describes for the first time how a spreading wave of disruption and the flow ...

Researchers used MRI to show yawning drives cerebrospinal fluid and venous blood out of the skull. This unique flow pattern ...

Scientists at the Institute for Basic Science (IBS) have uncovered a non-invasive method to boost the brain’s natural waste drainage system—a discovery that they suggest could open new avenues for ...

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 ...
