The influence of intracerebrally injected biogenic amines and cyclic AMP dibutyrate on duration of sleep induced with hexobarbital (50 mg/kg i.v.) in rats was studied. Duration of sleep was markedly prolonged by adrenaline, noradrenaline, dopamine, 5-hydroxydopamine and acetylcholine. Cyclic AMP dibutyrate injected 30 minutes before hexobarbital shortened time of sleep. The role of biogenic amines in hexobarbital-induced sleep is discussed.
