Abstract

Memory performances are not constant but undergo fluctuations whose periodicity may be analyzed. Low frequency infradian rhythms (periods longer than 28 hours), circadian rhythms (periods between 20 and 28 hours) and ultradian rhythms (periods less than 20 hours) are involved in memory disorders. Paradoxical sleep represents a preferential period in which certain processes, such as the activation of the central nervous system for example, may facilitate learning process. Relations between sleep and memory lead to the discussion of the incidence of the cyclic nature of sleep (and notably the rhythm of 90 minutes' paradoxical sleep) on the daily course of cerebral activation and its effects on the variable aptitude of our capacity for remembering. The close interrelation between biological rhythms and cognition is demonstrated using two examples of mental disorders in which severe memory deficiencies are observed.

记忆过程的时间生物学节律限制。
记忆性能不是恒定的,而是有波动的,其周期性可以分析。低频次昼夜节律(周期大于28小时)、昼夜节律(周期在20至28小时之间)和超昼夜节律(周期小于20小时)与记忆障碍有关。矛盾睡眠代表了一个特定过程的优先阶段,比如中枢神经系统的激活,可能会促进学习过程。睡眠和记忆之间的关系导致了关于睡眠的周期性(特别是90分钟的矛盾睡眠的节奏)在日常大脑活动过程中的发生率的讨论,以及它对我们记忆能力的可变能力的影响。生物节律和认知之间的密切联系用两个精神障碍的例子来证明,其中观察到严重的记忆缺陷。
