Question

Quizplus · Accepted Answer

The first four sleep stages are considered non-rapid eye movement sleep (NREM). NREM sleep is characterized by a slower brain wave pattern and little to no eye movement. The four stages of NREM sleep are stages 1, 2, 3, and 4. Rapid eye movement (REM) sleep is the fifth stage of sleep, where most dreaming occurs. Paradoxical sleep is another term for REM sleep. Therefore, choice B is not accurate, and choice D is vague and unclear.
