Narcolepsy alters the pulsations that maintain the brain’s waste clearance system, shows a new study from the University of Oulu. The researchers’ discovery increases our understanding of the effects ...

Brain clearance involves three types of pulsation: cardiovascular pulsations generated by the heartbeat in the arteries, respiratory pulsations in the veins and cerebrospinal fluid spaces, and slow ...

A hormone produced by the brain, orexin, may play a central role in the functioning of the brain’s glymphatic system, which clears waste, according to a new study from the University of Oulu.

New research has found that people with narcolepsy type 1 exhibit patterns of slow brain pulsations that resemble those seen in healthy sleep. The findings, published in PNAS, suggest that orexin—a ...

Two discoveries -- one in the brains of people with heroin addiction and the other in the brains of sleepy mice -- shed light on chemical messengers in the brain that regulate sleep and addiction, ...
