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.
期刊介绍:
For over four decades, Trends in Neurosciences (TINS) has been a prominent source of inspiring reviews and commentaries across all disciplines of neuroscience. TINS is a monthly, peer-reviewed journal, and its articles are curated by the Editor and authored by leading researchers in their respective fields. The journal communicates exciting advances in brain research, serves as a voice for the global neuroscience community, and highlights the contribution of neuroscientific research to medicine and society.
