| Abstract: | Studies have been made on functional dissolution of the sleep cycle in albino rats due to immobilization of various duration. It was shown that 1-day immobilization increases microactivational representation in the EEG, facilitates rhythmic movements of the lower jaw, affects relative duration of the diurnal and nocturnal sleep, increases sleep fragmentation, and in some of the animals decreases the EEG amplitude. It is suggested that strong stress results in the return of sleep mechanisms to a more ancient level. |
