Abstract

Cortical activity is constantly fluctuating between distinct spatiotemporal activity patterns denoted by changes in brain state. States of cortical desynchronization arise during motor generation, increased attention, and high cognitive load. Synchronized brain states comprise spatially widespread, coordinated low-frequency neural activity during rest and sleep when disengaged from the external environment or 'offline'. The claustrum is a small subcortical structure with dense reciprocal connections with the cortex suggesting modulation by, or participation in, brain state regulation. Here, we highlight recent work suggesting that neural activity in the claustrum supports cognitive processes associated with synchronized brain states characterized by increased low-frequency network activity. As an example, we outline how claustrum activity could support episodic memory consolidation during sleep.

磁鼓与大脑同步状态
大脑皮层活动在不同的时空活动模式之间不断波动,这些活动模式由大脑状态的变化表示。大脑皮层的非同步状态出现在运动产生、注意力增强和高认知负荷时。大脑同步状态包括在休息和睡眠时,脱离外部环境或 "离线 "时,在空间上广泛、协调的低频神经活动。视网膜是一个小型皮层下结构,与大脑皮层有密集的相互联系,这表明视网膜受大脑状态调节的影响或参与大脑状态调节。在这里,我们将重点介绍最近的研究,这些研究表明,鼓室的神经活动支持与同步大脑状态相关的认知过程,而同步大脑状态的特点是低频网络活动增加。举例来说,我们概述了鼓室活动如何支持睡眠中的外显记忆巩固。
