Neurovascular coupling: motive unknown

PJ Drew - Trends in neurosciences, 2022 - cell.com
In the brain, increases in neural activity drive changes in local blood flow via neurovascular
coupling. The common explanation for increased blood flow (known as functional …

Cerebrospinal fluid flow

DH Kelley, JH Thomas - Annual Review of Fluid Mechanics, 2023 - annualreviews.org
Circulation of cerebrospinal fluid and interstitial fluid around the central nervous system and

The interconnected causes and consequences of sleep in the brain

LD Lewis - Science, 2021 - science.org
Sleep is essential for brain function in a surprisingly diverse set of ways. In the short term,
lack of sleep leads to impaired memory and attention; in the longer term, it produces …
