Question

Quizplus · Accepted Answer

During REM sleep, there is a high degree of inhibition of motor neuron activity, which is why the body experiences temporary paralysis also known as REM atonia. In contrast, during NREM sleep, there is less inhibition of motor neuron activity, allowing for movements such as tossing and turning. Of the NREM stages, Stage 4 has the lowest degree of inhibition, but still not as much as during REM sleep.
