This review covers cognitive and electroencephalographic studies of the ultradian rhythm of alternating cerebral hemispheric activity found in humans and animals. This endogenous alternation of right and left dominance ranges in periodicity from about 25 to 300 min with peaks between 90-200 min during waking and around 100 min during sleep. Studies of lateralized EEG activity during sleep are reported as correlates of the REM-NREM sleep cycle. Studies of lateralized ultradian rhythms of EEG during wakefulness reveal a correlation between hemispheric dominance and the nasal cycle. The rhythm of cerebral dominance has also been identified with tests of lateralized cognitive performance using left and right hemisphere dependent tasks. Awakening from REM or NREM sleep is associated with different effects on left or right hemispheric dominance. This rhythm plays an important role in cognitive performance, memory processes, visual perception, levels of arousal and performance, mood, and individual and social behavior.
本综述涵盖了对人类和动物中发现的大脑半球交替活动的超日节律的认知和脑电图研究。这种左右优势的内源性交替周期在约25至300分钟之间，清醒时峰值在90 - 200分钟之间，睡眠时约为100分钟。睡眠期间脑电活动偏侧化的研究报告为快速眼动睡眠 - 非快速眼动睡眠周期的相关因素。清醒时脑电超日节律偏侧化的研究揭示了半球优势与鼻周期之间的相关性。大脑优势节律也通过使用依赖于左右半球的任务进行的偏侧化认知表现测试得以确定。从快速眼动睡眠或非快速眼动睡眠中醒来对左右半球优势有不同影响。这种节律在认知表现、记忆过程、视觉感知、唤醒水平和表现、情绪以及个体和社会行为中起着重要作用。
