One key role of sleep involves cerebrospinal fluid, which surrounds and protects the brain. During sleep, CSF helps remove waste that accumulates during waking hours. In a 2019 study, Lewis and her ...

Yawning and deep breathing each have different effects on the movement of fluids in the brain, and each of us may have a ...

Sleep deprivation triggers CSF movements during wakefulness, briefly pushing the brain into a sleep-like state that disrupts ...

New research shows sleep deprivation can push the awake brain into a sleep-like state, disrupting attention and brain fluid ...

Researchers at the Massachusetts Institute of Technology (MIT) say short lapses in attention after poor sleep owe to sudden ...

Toronto, Ontario, Jan. 08, 2026 (GLOBE NEWSWIRE) -- A new breakthrough study from the Rotman Research Institute at Baycrest, University of Toronto (Motsenyat et al., Brain Stimulation 2025) shows that ...

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 ...

Typically, CSF flow during sleep helps get rid of built-up waste from the day. Scientists wanted to know how it might be affected by sleep deprivation, so they recruited 26 volunteers to perform tasks ...

In a 2019 study, Lewis and her colleagues showed that CSF flow during sleep follows a "rhythmic" pattern in and out of the brain, and that the flows are linked to changes in brain waves during sleep.

A major international study has uncovered a new biological clue that could help predict dementia long before memory problems arise. Researchers from the University of Cambridge and Zhejiang University ...
