Sleep electroencephalograms (EEG) and electrooculograms were recorded in nine young adult males on a baseline night, a night in which they were deprived of an average of 3 hr 27 min of sleep by early awakening, and on a recovery night. Records were analyzed by visual sleep stage scoring and period-amplitude analysis; the results of both were tabulated by successive nonrapid eye movement periods (NREMPs) and rapid eye movement (REM) periods. Neither visually scored delta nor REM measures were affected by this substitution of waking for sleep. Although there was a significant increase in the 0-3-Hz time/epoch on the recovery night, this finding was not confirmed in the accompanying report. These results, taken in association with data from previous studies, are consistent with the hypothesis that, in an acute experiment, visually scored delta and computer-measured 0-3-Hz EEGs increase above the baseline levels only if there has been loss of stage 3/4 EEG (or of sleep) from the first two NREMPs. The findings here are inconsistent with older reports and indicate that further parametric data are required to construct a quantitative model of the relation of sleep EEG waveforms to the duration of prior waking.
对9名年轻成年男性在基线夜、因早醒平均剥夺3小时27分钟睡眠的一晚以及恢复夜进行睡眠脑电图（EEG）和眼电图记录。记录通过视觉睡眠阶段评分和周期-振幅分析进行分析；两者结果均按连续非快速眼动期（NREMPs）和快速眼动（REM）期列表。无论是视觉评分的δ波还是REM测量值都不受这种用清醒替代睡眠的影响。尽管在恢复夜0-3赫兹的时间/时段有显著增加，但该发现未在随附报告中得到证实。这些结果与先前研究的数据相结合，与以下假设一致：在急性实验中，只有在前两个NREMPs中出现3/4期EEG（或睡眠）缺失时，视觉评分的δ波和计算机测量的0-3赫兹EEG才会高于基线水平增加。这里的发现与早期报告不一致，表明需要更多参数数据来构建睡眠EEG波形与先前清醒持续时间关系的定量模型。
