[Effect of partial deprivation of slow-wave sleep on the structure of the sleep-wakefulness cycle].
In cats, partial (35% and 55%) deprivation of slow-wave sleep by way of inducing fragments of isolated EEG wakefulness in response to electrical stimulation of brain-stem activating structures, was shown to lead to an enhancement of behavioral sleep and reduction of paradoxical sleep. The reduction of paradoxical sleep is particularly obvious if the deprivation of slow-wave sleep is induced by fragments of behavioral wakefulness. In these situations no rebound of paradoxical sleep is observed in post-deprivation period. The causal interrelationships and interdependence of different phases of the sleepwakefulness cycle as well as interaction of EEG and behavioral mechanisms of sleep and wakefulness, are discussed.
