Question

Quizplus · Accepted Answer

REM sleep is paradoxical because although the brain is very active and individuals often experience vivid dreams, the major skeletal muscles of the body are paralyzed, which prevents individuals from physically acting out their dreams. This is also known as atonia. Option B is incorrect because during REM sleep, the majority of skeletal muscles are paralyzed. Option C is incorrect because brain activity is actually higher during REM sleep compared to other sleep stages. Option D is incorrect because while dreams occur more frequently during REM sleep, this is not what makes it paradoxical.
