title: [Factor analysis of the mechanisms of the structure of sleep-wakefulness cycle].
abstract: As a result of factor analysis of the structure of the cat sleep--wakefulness cycle, six factors have been defined, regarded as factors of "paradoxical sleep", "structure of slow-wave sleep", "transitions or delta-sleep", "sleep of medium depth", "stage of sleep spindles" and "delta sleep". Along with the detected certain independence of the apparatuses controlling individual sleep stages it was shown that mechanisms of paradoxical sleep may determine the organization of the entire sleep--wakefulness cycle, representing a peculiar system-forming factor. A considerable part in cessation of the fast sleep, as well as in the sleep general mechanisms is played by the apparatuses responsible for the transitional processes between the stages.
