Quizplus · Accepted Answer

This statement is true. Cholinergic activity, which is mediated by the release of the neurotransmitter acetylcholine, is high during wakefulness and REM sleep but lower during NREM (non-REM) sleep. This is one of the factors that contribute to the differences in brain activity and physiological processes between these sleep stages.
