The circadian rhythm in the EEG of the waking state was investigated in six healthy volunteers who were deprived of sleep for 48 (3 probands) and 30 (3 probands) hours. Every hour an EEG was recorded, the body temperature was measured, and the probands rated their fatigue themselves. The EEG parameterized by the partial autocorrelation function shows a circadian change in all probands. The causal link between EEG and body temperature indicates that the circadian rhythm in the EEG is at least partly autonomous of external time cues and the sleep-wake cycle.
对6名健康志愿者的清醒状态脑电图昼夜节律进行了研究，这些志愿者分别被剥夺睡眠48小时（3名受试者）和30小时（3名受试者）。每小时记录一次脑电图，测量体温，并让受试者自行评估疲劳程度。通过偏自相关函数参数化的脑电图在所有受试者中均显示出昼夜变化。脑电图与体温之间的因果联系表明，脑电图的昼夜节律至少部分独立于外部时间线索和睡眠-清醒周期。
