Question

Quizplus · Accepted Answer

Brain activity during sleep is not uniform and changes throughout the night. It is correlated with changes in muscle tension, breathing, and other physiological responses. This is why different stages of sleep (such as REM and non-REM) can be distinguished based on changes in brain activity as well as physiological changes in the body. Option A is incorrect as brain activity during sleep is not uniform. Option B is also incorrect as brain activity during sleep is different from that during the waking state. Option C is incorrect as brain activity during sleep is not nonexistent.
