88 adult male rats were divided into 9 groups. Group I and II served as controls. The rats of group III were repeatedly aroused during 4 days at the very onset of each paradoxical sleep period by direct MRF stimulation. This deprivation reduced the daily amount of paradoxical sleep by 70%, while the slow wave sleep was reduced by 10% only. In group IV, the animals were given food and water for one hour a day only. Groups V and VI were subjected to immobilization and cold stress, respectively. Groups VII, VIII and IX were deprived of paradoxical sleep on platforms of 15, 11 and 6.5 cm in diameter, respectively. Stress was estimated by the classical Selye's triad: weight of adrenals and thymus and gastric ulceration. Emotionality was measured in the open field and also by self-stimulation of the lateral hypothalamus. Neither emotional behaviour disturbances nor stress features were found after paradoxical sleep deprivation in the group III. Moreover, this deprivation induced a slight, though significant, reduction in adrenals weight. Also, no changes in emotional behaviour were noted in the stress-exposed group V and VI. Only the interplay between REM-sleep deprivation and stress on the platforms in groups VII, VIII and especially IX led to a considerable shift in emotionality.
