Data from studies of naps and of shifted sleep were used to determine the relationship between two measures of rapid eye movement (REM) sleep (percentage of REM in the first 2 hr of sleep and REM latency) and prior wakefulness. For each sample, we calculated the difference between the observed value and that predicted by a cosine function that estimated the circadian rhythm of REM sleep propensity. The difference values were found to correlate reliably with hours and log hours of prior wakefulness. We conclude that while REM sleep is regulated in part by an endogenous circadian oscillator, it is also influenced by the duration of prior wakefulness.
来自小睡研究和睡眠时相转换研究的数据被用于确定快速眼动（REM）睡眠的两种测量指标（睡眠最初2小时内REM的百分比和REM潜伏期）与先前清醒时间之间的关系。对于每个样本，我们计算了观测值与由估计REM睡眠倾向昼夜节律的余弦函数预测值之间的差异。发现这些差异值与先前清醒的小时数和小时数的对数可靠相关。我们得出结论，虽然REM睡眠部分受内源性昼夜节律振荡器调节，但它也受先前清醒持续时间的影响。
