Abstract

Neurophysiological, neurochemical and neuropharmacological evidence indicates that cerebral monoamines are important regulators of wakefulness and sleep besides cerebral amino acid-ergic and peptidergic systems. The cerebral monoamines noradrenaline, dopamine and acetylcholine are positively involved in electroencephalographic aspects of waking and paradoxical or REM sleep. A high level of noradrenergic transmission facilitates waking, and a lower, moderate level facilitates REM sleep. Serotonin is involved in the regulation of synthesis, storage and release of sleep inducing factors, and in the gating mechanisms of REM sleep. Histamine neurons play a role in the regulation of vigilance during waking state. These neurotransmitter systems are important targets for drug actions.
