设计了设备和程序来量化睡眠期间低振幅下巴和嘴唇肌电图（emg）的相对无噪声记录。共记录了5只年轻成年雌性小鼠28个快速眼动期。强直性肌电图水平在快速眼动期前5分钟开始向夜间最低水平下降。除了非常罕见的例外，夜间最低的肌电图水平在快速眼动睡眠期间保持不变。在快速眼动期之后的20分钟非快速眼动期睡眠期间，平均肌电图水平高于快速眼动期，但低于快速眼动期之前的20分钟非快速眼动期睡眠期间记录的水平。这种强直性肌电图变化模式发生于夜间前3个快速眼动期。
Equipment and procedures were devised for quantifying relatively noise‐free recordings of low amplitude chin and lip electromyograms (EMGs) during sleep. A total of 28 REM periods were recorded from 5 young adult femaleSs. Tonic EMG levels tended to decline toward their lowest level of the night beginning 5 min in advance of REM periods. With very rare exceptions, the lowest EMG levels of the night were maintained throughout REM sleep. During the 20 min of NREM sleep which followed REM periods, mean EMG levels increased over the REM levels but were lower than those recorded during the 20 min of NREM sleep which preceded the REM periods. This pattern of tonic EMG variation obtained for each of the first 3 REM periods of the night.
