Altered Coactive Micropattern Connectivity in the Default-Mode Network during the Sleep-Wake Cycle
Neural Plasticity November 23, 2020 Yan Cui, Qiao Chen, Yang Xia et al.
The default-mode network (DMN) in rats contains three coactive micropattern (CAMP) networks that show greater functional connectivity and efficiency than the original DMN structure across all states of consciousness. In the waking state, these three networks do not differ significantly in connectivity or network properties, but in two sleep states they exhibit distinct characteristics, suggesting each plays a specific role. Changes in the CAMP networks' connectivity and properties mirror those of the original DMN, indicating that different states of consciousness intrinsically affect DMN dynamics. These findings deepen understanding of how DMN functional connectivity alters during the sleep-wake cycle.
