摘要

亚慢振荡(infra-slow oscillation, ISO)是一种介于0.01~0.5 Hz的大脑节律。亚慢振荡在大脑中广泛分布、有独特的活动模式、与高频神经活动相耦合等特征使它具有重要的生理与心理意义。从生理学角度来看，ISO可能由丘脑、胶质细胞、离子动态活动所产生。从心理学角度来看，ISO的频率、波幅和相位调节不同的认知活动。ISO研究拓展了神经节律研究的边界，促进了节律相关脑功能理论的发展和完善。

Abstract

 Infra-slow oscillation (ISO) is a kind of brain rhythm between 0.01 and 0.5 Hz. ISO is widely distributed in multiple brain regions. As an important psychophysiological activity, the ISO interacts with high-frequency neural rhythm via cross-frequency coupling, but has different activity patterns from high-frequency neural activity. Physiologically, the ISO may be generated by the dynamic activity of thalamus, glia, and ions. Psychologically, the frequency, amplitude, and phase of ISO could all regulate cognitive activities, but in different ways. Investigations on the ISO expands the neural rhythm research to lower frequency range, further promoting the construction of rhythmic theory of brain function.

Key words: infra-slow oscillation; thalamus; glia; neural rhythm; cognitive efficiency
