Under the postulated existence of a mechanism regulating the NREM sleep- REM sleep sequence and a reset of this mechanism by long awakenings, the variability of sleep cycle in the rat was studied. Awakenings of various durations were included in the definition of sleep cycle boundaries. Results show that an intervening awakening of 1 min is close to the limit under which the same cycle seems to be resumed after the awakening and above which the previous cycle is abortive and a new cycle will start after the next sleep onset.
在假定存在调节非快速眼动睡眠-快速眼动睡眠序列的机制以及长时间觉醒可重置该机制的情况下，对大鼠睡眠周期的变异性进行了研究。各种时长的觉醒被纳入睡眠周期边界的定义中。结果表明，1分钟的中间觉醒接近这样一个极限：低于此极限，觉醒后似乎会恢复同一个周期；高于此极限，前一个周期则终止，在下一次睡眠开始后会开始一个新的周期。
