REM sleep and wakefulness are related because REM sleep is characterized by brain activity patterns, such as beta waves and neural activity levels, that closely resemble those observed during wakefulness [1], [2], and [3]. Additionally, they are physiologically linked by the neurotransmitter norepinephrine, which actively promotes wakefulness while inhibiting REM sleep [4].

claimNorepinephrine is released from norepinephrine-containing neurons of the locus coeruleus, which inhibits rapid eye movement (REM) sleep, promotes wakefulness, and communicates with the thalamus, hypothalamus, basal forebrain, and cortex.
claimREM sleep is associated with dreaming and is characterized by beta waves on an EEG, which are similar to brain waves during wakefulness.

claimBrain activity decreases from wakefulness during NREM sleep, whereas during REM sleep, brain activity levels are similar to wakefulness, except for increases in motor and sensory areas.

claimREM (Rapid Eye Movement) sleep is characterized by brain activity resembling wakefulness and temporary body paralysis to prevent acting out dreams.
