We studied the effect of alternating 45-min light-dark (L-D) cycles on sleep in rats. Introduction of short L-D cycles did not abolish the normal circadian rhythm of sleep-wake activity. The amount of non-REM sleep was however increased in the L and decreased in the D 45-min periods. REM was promoted in the D and inhibited in the L 45-min periods. The influence of L-D or D-L transitions depended on the sleep wake activity immediately before the transition.
我们研究了45分钟明暗交替（L-D）周期对大鼠睡眠的影响。引入短的L-D周期并未消除睡眠-觉醒活动的正常昼夜节律。然而，在45分钟的光照期非快速眼动睡眠量增加，在45分钟的黑暗期减少。快速眼动睡眠在黑暗期增加，在光照期减少。明暗或暗明转换的影响取决于转换前的睡眠-觉醒活动。
