Question

Quizplus · Accepted Answer

Brain activity during sleep is not uniform and changes throughout the night. It is not very similar to activity during the waking state either. Brain activity slows down during non-REM sleep but becomes more active during REM (rapid eye movement) sleep, which is where most dreaming occurs. These changes in brain activity are correlated with changes in muscle tension, breathing, and other physiological responses. Hence, option D is the best choice.
