Instability of brain connectivity during nonrapid eye movement sleep reflects altered properties of information integration.
Human Brain Mapping August 1, 2019 Yi-Chia Kung, Chia-Wei Li, Shuo Chen et al.
Nonrapid eye movement (NREM) sleep is associated with fading consciousness in humans. Recent neuroimaging studies have demonstrated the spatiotemporal alterations of the brain functional connectivity (FC) in NREM sleep, suggesting the changes of information integration in the sleeping brain. However, the common stationarity assumption in FC does not satisfactorily explain the dynamic process of...
