Slow eye movements (SEMs) were analyzed in 28 young adult females during daytime sleep. Data from transitional periods of each EEG stage were obtained by accumulating its epoch series synchronized to the onset or termination of the other stages. Sleepiness was reported by the subject by pressing a button switch. SEMs were prominent at the transitional period of stage W approaching the onset of stage 1 (sleep tendency). They declined with deepening of sleep at the transitional periods of EEG stages 22 and 2, and disappeared completely during slow wave sleep (SWS) periods. The recovery of SEMs occurred towards awakening at every EEG transitional period except for SWS. The individual difference in the appearance of SEMs was partly explained by a positive correlation with stage 3 latency: the longer the latency was, the larger the mean SEMs. Perceived sleepiness increased in proportion to SEMs during the entry and re-entry periods to sleep. These results suggest that SEMs are strongly associated with a wake-sleep transition.
在白天睡眠期间，对28名年轻成年女性的慢眼动（SEMs）进行了分析。通过累积与其他阶段的开始或结束同步的时段序列，获得每个脑电图（EEG）阶段过渡期的数据。受试者通过按下按钮开关报告困倦程度。慢眼动在清醒（W）阶段接近第1阶段开始（睡眠倾向）的过渡期很突出。在EEG第2阶段和第2阶段的过渡期，随着睡眠加深，它们会减少，并在慢波睡眠（SWS）期间完全消失。除了慢波睡眠外，在每个EEG过渡期，随着接近觉醒，慢眼动会恢复。慢眼动出现的个体差异部分可由与第3阶段潜伏期的正相关来解释：潜伏期越长，平均慢眼动越大。在入睡和重新入睡期间，感知到的困倦程度与慢眼动成比例增加。这些结果表明，慢眼动与清醒-睡眠转换密切相关。
