Question

Quizplus · Accepted Answer

Acetylcholine is the neurotransmitter that has been associated with activation of REM (rapid eye movement) dreams. The release of acetylcholine in the brainstem is known to trigger the onset of REM sleep, and drugs that block acetylcholine receptors have been found to reduce the occurrence of REM sleep and therefore dreams. Serotonin and norepinephrine are also involved in the regulation of sleep, but they are not specifically associated with REM dream activation. Melatonin is a hormone that is involved in the regulation of circadian rhythms and sleep-wake cycles, but it is not a neurotransmitter and is not directly involved in dream processes.
