Cats with chronically implanted electrodes were selectively deprived of paradoxical sleep for 1-26 days by the swimming pool and electric shock techniques. The need for paradoxical sleep was demonstrated by the progressive diminution of the intervals between attempts to enter this phase. Deprivation of this phase of sleep for more than a week produced somnolence, muscular hypotony, sexual excitement, tachycardia, and a picture resembling hallucinations. At the end of this deprivation there was a selective paradoxical sleep rebound, and up to 60 of the first 6 hours was spent in this phase of sleep. Substances with an inhibitory effect on paradoxical sleep, such as atropine, monoamine oxidase inhibitors, and reserpine, were studied, and the results are discussed in light of a neurohumoral hypothesis of sleep.
