Question

Quizplus · Accepted Answer

REM sleep is characterized by temporary skeletal muscle inhibition, except for ocular muscles and diaphragm. This is thought to prevent the dreamer from acting out dreams and potentially harming themselves or others. Other bodily functions, such as heart rate and blood pressure, may fluctuate during REM sleep but do not necessarily decrease overall. Additionally, the brain is actually quite active during REM sleep, with increased activity in areas such as the limbic system and visual cortex.
