通过对地图的研究，评估了人类睡眠期间先前觉醒的持续时间与EEG功率密度之间的关系。在1000小时，1200小时，1400小时，1600小时，1800小时，2000小时，和0400小时，通过安排午睡，先前清醒的持续时间从2到20小时不等。相反，睡眠lavelets，表现出在下午的最小值，在三角洲和θ频率的EEG功率密度是一个单调函数的先前清醒的持续时间。这些数据支持了这一假设，即非快速眼动睡眠期间的EEG功率密度仅由先前的睡眠和觉醒历史决定，而不是由类时钟机制决定。
The relation between the duration of prior wakefulness and EEG power density during sleep in humans was assessed by means of a study of maps. The duration of prior wakefulness was varied from 2 to 20 hr by scheduling naps at 1000 hr, 1200 hr, 1400 hr, 1600 hr, 1800 hr, 2000 hr, and 0400 hr. In contrast to sleep latencies, which exhibited a minimum in the afternoon, EEG power densities in the delta and theta frequencies were a monotonic function of the duration of prior wakefulness. The data support the hypothesis that EEG power density during non-rapid eye movement sleep is only determined by the prior history of sleep and wakefulness and is not determined by clock-like mechanisms.
