REM Sleep

The Rapid Eye Movement sleep  phase is also called as paradoxical sleep (PS) and often desynchronized sleep due to physiological similarities, including quick, low-voltage desynchronized brain waves, to waking states. REM and non-REM sleep switch during one sleep cycle, and this in human adults spans around 90 minutes. Organisms through REM sleep revoke central homeostasis, allowing large breathing fluctuations, thermoregulation, and circulation that do not take place in any other mode of sleeping or waking. Despite the paralysis of the body , the brain acts kind of awake, with cerebral neurons firing at the same overall intensity as wakefulness.
