The effects of nonpharmacologically-induced deprivation of paradoxical sleep for a 24 hour period were studied in rabbits. Response characteristics commonly associated with the deprivation procedure in other species were observed, as well as features apparently peculiar to the rabbit. Like other mammals, rabbits: (1) show increased attempts to experience PS during the deprivation procedure relative to the baseline occurrence of PS; (2) become increasingly difficult to arouse from PS as the deprivation period progresses; (3) show increased amounts of PS (rebound) in post-deprivation recordings relative to baseline; and (4) compensate for only one-third of the PS deficit incurred during deprivation. Rabbits' response to PS deprivation differs from other mammals in the following ways: (1) the deprivation procedure is truly selective, significantly affecting only amounts of PS and not total sleep time or other sleep stages; (2) the rebound response is restricted to the light phase of the light-dark cycle on the first recovery day; and (3) as indexed by eye movement density, phasic activity during PS is not enhanced during the recovery period. Given that the crucial factor in the PS deprivation-compensation phenomenon is thought to be the deprivation and subsequent enhanced occurrence of phasic events, and considering that events within the oculomotor system have been emphasized in this regard, the results of this investigation suggest the existence of species differences regarding the nature and form of the compensatory response to PS deprivation.
在兔子身上研究了非药物诱导的24小时异相睡眠剥夺的影响。观察到了与其他物种的剥夺程序通常相关的反应特征，以及兔子特有的特征。与其他哺乳动物一样，兔子：(1)在剥夺程序期间，相对于异相睡眠的基线发生率，表现出增加的体验异相睡眠的尝试；(2)随着剥夺期的进展，从异相睡眠中唤醒变得越来越困难；(3)在剥夺后记录中，相对于基线，异相睡眠量增加(反弹)；(4)仅补偿剥夺期间产生的异相睡眠不足的三分之一。兔子对异相睡眠剥夺的反应在以下方面与其他哺乳动物不同：(1)剥夺程序是真正有选择性的，仅显著影响异相睡眠量，而不影响总睡眠时间或其他睡眠阶段；(2)反弹反应仅限于恢复第一天的明暗周期的光照阶段；(3)以眼球运动密度为指标，在恢复期间，异相睡眠期间的相位活动没有增强。鉴于异相睡眠剥夺-补偿现象的关键因素被认为是剥夺以及随后相位事件的增强发生，并且考虑到在这方面动眼系统内的事件已被强调，本研究结果表明在对异相睡眠剥夺的补偿反应的性质和形式方面存在物种差异。
