Question

Quizplus · Accepted Answer

Sleep medications, such as benzodiazepines, work by increasing the activity of gamma-aminobutyric acid (GABA), which is an inhibitory neurotransmitter that slows down the activity in the brain and promotes relaxation and drowsiness. Serotonin and norepinephrine are involved in regulating mood and arousal, respectively, but not directly related to sleep medications. Acetylcholine is involved in several brain functions, including cognitive processes and muscle control, but its role in sleep is unclear.
