the brain’s motor cortex is active, but the body is not

Detailed explanation-1: -REM sleep is called “paradoxical” because of its similarities to wakefulness. Although the body is paralyzed, the brain acts as if it is somewhat awake, with cerebral neurons firing with the same overall intensity as in wakefulness.
Detailed explanation-2: -So, REM sleep truly has earned the name “paradoxical sleep, ‘’ first given to it by the French researcher Michel Jouvet because of its waking EEG during behavioral sleep.
Detailed explanation-3: -Motor responses were evoked during sleep using stimuli identical to those used in wakefulness. Response amplitudes were depressed during slow wave sleep (SWS) and enhanced or the same during REM sleep. These findings suggest that the susceptibility of the human motor cortex to stimulation is enhanced during REM sleep.
