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 ...

Cerebrospinal fluid (CSF) is a clear and watery liquid that flows in and around the brain and spinal cord. Its functions include protecting parts of the nervous system, delivering nutrients and ...

Biomedical engineers at Duke University have developed a technique to noninvasively visualize the brain's waste-removal ...

Scientists: Please redraw the brain waste clearance map. Until now, they relied on tracking drainage by injecting tracers into the CSF, an approach that suggested most material ultimately drains into ...

When you’re short on sleep and your focus suddenly drifts, your brain may be briefly slipping into cleanup mode. Scientists discovered that these attention lapses coincide with waves of fluid washing ...

Researchers led by Masako Tamaki at the RIKEN Center for Brain Science in Japan report a link between deep sleep and cerebrospinal fluid, the clear liquid that surrounds and supports the brain and ...

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 device that massages the face and neck boosts the brain’s waste disposal system, suggesting it could reduce the severity of conditions like Alzheimer’s disease. Cerebrospinal fluid (CSF) bathes our ...

In the Alzheimer’s field, conventional wisdom holds that the growth of amyloid plaques in the brain soaks up Aβ42 peptide, depleting it from cerebrospinal fluid. Now, in the February 12 Nature Aging ...

MRI image of the brain with the lateral ventricles colored in blue. The ventricles are filled with cerebrospinal fluid. Researchers led by Masako Tamaki at the RIKEN Center for Brain Science in Japan ...
