Yawning can help the flow of cerebrospinal fluid and venous blood flow, suggesting a regulation of neurofluids and increase ...

Sleep deprivation causes attentional lapses that coincide with coordinated changes in brain activity, pupil diameter, blood ...

Although yawning seems like a small, everyday action, recent studies have found that it causes an unexpected reaction in the ...

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 ...

Chiari malformation type I (CMI) is a congenital neurological disorder characterized by the herniation of cerebellar tonsils through the foramen magnum, leading to impaired cerebrospinal fluid (CSF) ...

Yawning has long been dismissed as a sign of boredom or fatigue, a social cue we mostly try to suppress in meetings and on video calls. New brain imaging work suggests that instinct is misplaced. When ...

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 ...

Researchers have discovered, in rodents, that fluid that circulates through the brain flows to areas critical for normal brain development and function, suggesting that disruptions to its circulation ...

Evidence of sleep-dependent low-frequency (less than 0.1 Hz) global brain activity in the clearance of Alzheimer's disease-related toxin buildup is presented in new research. This neuronal activity ...
