研究表明，对外部和内部事件的有意识指数既表现出大约90-100分钟（成年期）的超昼夜变化，也表现出24小时的昼夜变化。在遗传学上较古老的超日节律代表了N. Kleitman（1963）的理论是连续的，并且似乎包含了在觉醒和NREM和REM睡眠中的这种周期性的思想和幻想类型的心理活动的交替。这表明BRAC中固有的左右半球相对优势的连续周期性交替。在一个昼夜活跃的成年人中，意识的昼夜节律波动通常在通常的睡眠开始后的第1小时显示出最低水平，如果这个人保持清醒，则在大约5-6：00 AM时出现较晚的下降。经过一夜的睡眠，白天的意识和表现在早上有所改善，通常表现为下午早些时候的“午餐后下降”，下午晚些时候和傍晚的持续增加，以及睡眠开始前的下降。据推测，皮层，主要是前额叶，超极化在NREM睡眠重置皮层更新的高层次感知意识的第二天。意识不是一个静态的属性，而是在水平和类型上显示出明确的生物节律波动。（法文摘要）（参考文献41/2页）（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
Research indicates that indices of conscious awareness of external and internal events exhibit both ultradian approximately 90-100 min (in adulthood) and circadian 24-hr variations. The phylogenetically older ultradian rhythm represents the basic rest-activity cycle (BRAC) of N. Kleitman (1963), is continuous, and appears to contain alternation of mental activity of thought-like and fantasy type at this periodicity in wakefulness and in NREM and REM sleep. This suggests continuous cyclic alternation of relative predominance of the left and right hemispheres inherent in the BRAC. Superimposed circadian fluctuations of consciousness in a diurnally active adult typically show lowest levels in the 1st hrs after usual sleep onset and a later dip at about 5-6: 00 AM if the person remains awake. After a night of sleep, daytime consciousness and performance improve in the morning, usually show an early afternoon" post-lunch dip," a sustained increase in the late afternoon and early evening, and a decrease before sleep onset. It is postulated that cortical, mainly prefrontal, hyperpolarization in NREM sleep resets the cortex for renewed high-level perceptual awareness the next day. Consciousness is not a static attribute but shows definite biorhythmic fluctuations in level and type.(French abstract)(41/2 p ref)(PsycInfo Database Record (c) 2022 APA, all rights reserved)
