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 ...

Researchers report that the flow of cerebrospinal fluid in the brain is linked to waking brain activity. The study demonstrates that manipulating blood flow in the brain with visual stimulation ...

In 10 male patients, forty-four to seventy-eight years of age, with varying degrees of respiratory insufficiency, blood and cerebrospinal fluid were drawn simultaneously from the brachial artery and ...

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” ...

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 ...

Yawning can impact the flow of cerebrospinal fluid and venous blood flow, suggesting a regulation of neurofluids and increase in carotid arterial blood flow.

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 ...

Although yawning seems like a small, everyday action, recent studies have found that it causes an unexpected reaction in the fluid protecting the brain. A research team in Australia reports that a ...
