[Interdependence of learning and paradoxical sleep in the cat].
The effect of learning sessions on the structure of the sleep-wakefulness cycle, as well as the effect of paradoxical sleep (PS) deprivation (PSD) following learning sessions, on the acquisition and extinction of instrumental alimentary reflexes to two feeders with sound discrimination, were studied on cats. The analysis of the data obtained led to following conclusions: The above learning sessions have no marked effect on the structure of the sleep-wakefulness cycle in the post-learning period, i.e. the percentage ratio of its phases is not altered by the increase of one of them. When PSD by non-emotional awakening is used, the number of PS onsets is not affected by learning sessions. This indicates that learning does not produce any considerable effect on the formation of PS need. PSD by non-emotional awakening following learning sessions does not retard the acquisition and extinction of the instrumental alimentary reflexes. The above data are interpreted as indicating that PS has no specific significance in memory trace consolidation during formation of long-term memory.
