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 ...

If you find it hard to focus after a wakeful night, it’s because your brain is busy trying to catch up on crucial ...

Researchers at Boston University, USA report that the flow of cerebrospinal fluid in the brain is linked to waking brain activity. Led by Stephanie Williams, and publishing in the open access journal ...

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 ...

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 ...

The space between the arachnoid and pia meningeal layers encasing the brain is a landscape of connective tissue, blood vessels, and cerebrospinal fluid. Scientists debate how that fluid moves within ...

Why sleep has restorative—or damaging—effects on cognition and brain health has been an enduring mystery in biology. Researchers think cerebrospinal fluid (CSF) may flush toxic waste out, “cleaning” ...

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 ...
