[The wakefulness-sleep cycle in rats with a genetic predisposition to catalepsy].
Neurophysiological studies on wakefulness-sleep cycle have been made in rats selected for hereditary inclination to catalepsy. It was shown that in these animals, the stage of delta-sleep is significantly reduced, whereas the duration of a superficial slow-wave sleep is increased. In a sleeping phase of the cycle, large amount of spindles in the range of alpha- and beta 1-oscillations was observed, especially significant in electrograms of n. caudatum and sensorimotor cortex. This activity is considered as a pathological manifestation of a transient hypnotic phase which includes the increase in immobilization of a cataleptic type.
