Emotional stress was developed in cats by putting them in one cage with dogs for 24 hours. Then the 24 hours sleep-walking cycles records revealed prolonged REM stage in day time or at night in five animals out of seven, and in six animals a general increase of REM sleep duration over 24 hours. Simultaneously, in six animals the length of drowsiness and of deep slow-wave sleep stages was reduced. Increased overall sleep duration in the 24 hours was recorded in five cats. Sleep changes dynamics analysis reveals three stages: 1) sharp shift of all sleep parameters--27%, 2) deviation in sleep parameters--34% and 3) returning to basic sleep parameters--in 38%. The conclusion is drawn that sleep disorders may be used as an index of higher nervous activity disturbance in waking state.
通过将猫与狗放在一个笼子里24小时来使猫产生情绪应激。然后，24小时的梦游周期记录显示，七只动物中有五只在白天或晚上的快速眼动（REM）阶段延长，六只动物在24小时内快速眼动睡眠时间总体增加。同时，六只动物的嗜睡期和深度慢波睡眠阶段的时长缩短。五只猫在24小时内的总睡眠时间增加。睡眠变化动态分析显示出三个阶段：1）所有睡眠参数急剧变化——27%，2）睡眠参数偏差——34%，3）38%的动物恢复到基本睡眠参数。得出的结论是，睡眠障碍可用作清醒状态下高级神经活动紊乱的指标。
