Neurons paralyze us during REM sleep

ScienceDaily - Health and Medicine News

During REM sleep, the brain inhibits the motor system, which makes the sleeper completely immobile. Researchers have identified a population of neurons that is responsible for this transient muscle paralysis. The animal model created will shed light on the origin of some paradoxical sleep disorders, and more particularly the condition that prevents this paralysis. It will also be most useful in the study of Parkinson's disease, since these pathologies are related.
