title: [Mechanism of internal inhibition (role of the sympathetic nervous system in sleep phenomena)].
abstract: It has been shown on cats that the role of the sympathetic nervous system in sleep phenomena is of an adaptive nature and is effected through chain neurohormonal reactions in which adrenaline possessing a two-phase action plays a major part: it induces excitation followed by sleep. Sleep is regarded as a variety of internal inhibition, elaborated as an adaptive reaction to the changing conditions of environment, which later becomes a behavioral reaction.
