Ten normal infants were studied at 2, 6, 12 and 20 weeks of age. EEG, respiratory rhythm, eye movements and chin EMG were recorded after the evening meal. Recording was continued during the stages of sleep. During the period of falling asleep the periods of REM sleep have been analyzed and compared with the periods of REM sleep occurring after non-REM sleep. REM sleep occurring on falling asleep and that occurring after non-REM sleep differed. Some of the following criteria were different at the earliest time of examination; absence of chin EMG activity, number of apnoeic episodes; other criteria (eye movements, respiration) differed during the first 5 months. The large number of eye movements at 2 and 6 weeks and the high respiratory rate, corresponding to that occurring during waking, could indicate that during REM sleep occurring on falling asleep, one is observing manifestations connected with the waking state.
对10名正常婴儿在2周、6周、12周和20周龄时进行了研究。晚餐后记录脑电图（EEG）、呼吸节律、眼动和颏肌电图（EMG）。睡眠各阶段均持续记录。在入睡期间，对快速眼动（REM）睡眠期进行了分析，并与非快速眼动（NREM）睡眠后出现的REM睡眠期进行了比较。入睡时出现的REM睡眠与NREM睡眠后出现的REM睡眠有所不同。在最早的检查时间，以下一些标准存在差异：颏肌电图活动缺失、呼吸暂停发作次数；其他标准（眼动、呼吸）在最初5个月内有所不同。2周和6周时大量的眼动以及与清醒时相当的高呼吸频率，可能表明在入睡时出现的REM睡眠期间，人们观察到了与清醒状态相关的表现。
