title: [About evolution of sleep-wakefulness cycle in vertebrates].
abstract: Data about behavioral, somato-vegetative and neurophysiological parameters of sleep and wakefulness in insects, cold- and warm-blooded vertebrates are provided. Hypotheses existing now about evolutionary formation of separate sleep phases and stages in vertebrates are considered. In the review are shown the data about correlations of quantitative characteristics of sleep and wake in some mammals with basic metabolic rate, lifestyle, environmental habits. The original experimental results at formation of neurophysiological characteristics of sleep and wake in vertebrates, phylogeny and in ontogeny of mature and immature mammals are provided in detail. On the basis of own concepts about evolutionary development of sleep-wakefulness cycle in vertebrates the interactions of telencephalic, diencephalic and rhombencepalic parts of brain in the processes of cycle wakefulness cycle integration are discussed.
