Question

Quizplus · Accepted Answer

Slow-wave sleep, also known as deep sleep, occupies a greater percentage of sleeping time than paradoxical sleep. During slow-wave sleep, the brain waves are slow and regular.

Answer: B
 Slow-wave sleep is harder to arouse sleepers from than paradoxical sleep. This is because the brain waves are slow and there is reduced activity in the brainstem regions that regulate consciousness.

Answer: C
 Slow-wave sleep is characterized by infrequent shifts in body position, as the body is relaxed and there is minimal muscle activity.

Answer: D
 Dreaming is not common during slow-wave sleep. Instead, dreams are more frequent during paradoxical sleep, also known as rapid eye movement (REM) sleep.
