title: [The visceral theory of sleep].
abstract: The review focuses on the studies which were undertaken in order to check our visceral hypothesis of sleep. The review presents also independent studies, results of which are in good agreement with this hypothesis. The visceral hypothesis proposes that during sleep central nervous system including all cortical areas switches from the processing of the exteroceptive information (visual, somatosensory and so on) to the processing of the interoceptive information coming from all visceral systems of an organism. This change of the cortical afferentation during sleep proposes simultaneous change of the directions of the efferent cortical information flows. In wakefulness these flows were directed towards the structures involved in organization of behavior. During sleep they will be redirected towards the structures undertaking visceral regulation. Analysis of the visceral hypothesis of sleep shows that many disorders connected with sleep-wake cycle can be explained by asynchronous switches of the cortical afferent and efferent information flows.
