Slow-wave sleep

Slow-wave sleep ( SWS), often referred to as deep sleep, consists of stage three of non-rapid eye movement sleep. Initially, SWS consisted of both Stage 3, which has 20-50 percent delta wave activity, and Stage 4, which has more than 50 percent delta wave activity.

Sleep Evolved Before Brains. Hydras Are Living Proof. | Quanta Magazine

The hydra is a simple creature. Less than half an inch long, its tubular body has a foot at one end and a mouth at the other. The foot clings to a surface underwater - a plant or a rock, perhaps - and the mouth, ringed with tentacles, ensnares passing water fleas.

"매일 늦잠, 게으른 사람일까? 유전일까?"

알람을 여러 개 맞춰놔도 일어나기가 쉽지 않다. 결국 늦잠을 자 헐레벌떡 이불 밖을 나오게 된다. 늦잠이 많은 사람은 특히 힘들다. 왜 그럴까? 왜 늦잠을 자게 되는 걸까? 우리 몸에는 시계 역할을 하는 유전자가 있다. 이 유전자들은 잠이 들고 깨는 시기, 필요한 수면의 양 등을 결정한다. 초파리에서는 per, tim, 클락(clock), cyc 유전자가 그 역할을 한다.

During sleep, slow electrical waves push fluid from around cells deep in the brain to its surface, where it is absorbed into the bloodstream through a sophisticated interface. There is growing evidence that the brain's waste-removal system is impaired in

Alzheimer's disease.

The brain makes a lot of waste. Now scientists think they know where it goes

The brain appears to rely on synchronized waves to wash out waste products, including toxins associated with Alzheimer's disease.
