TL;DR: Sp spontaneous activity of the visual cortex under anesthesia has the properties of neuronal avalanches and is suggested to have stronger temporal correlations between spiking activities of neurons that spanned longer time periods compared with spike clusters lacking power law statistics.

TL;DR: This Opinion article proposes that synchrony- and oscillation-based communication between brain networks can be described by a common theoretical framework and suggests a mechanism for control of the flow of information in the brain through nesting of slow and fast oscillations.

TL;DR: This analysis revealed a significant shift of the global dynamic working point of brain dynamics, from the edge of the transition between damped to sustained oscillations during wakefulness, to a stable focus during slow-wave sleep.

TL;DR: It is shown that criticality in cortical dynamics is not stationary, but fluctuates during anesthesia and between different vigilance states, and synchronized states are associated to criticality, large dynamical repertoire and prolonged epochs of eye closure.

TL;DR: This work proposes a novel mechanism which explains how synchronous spiking activity propagates across weakly connected brain areas supported by oscillations, and shows how the state of ongoing activity could affect the communication through resonance and proposes that modulations of the ongoing activity state could influence information processing in distributed cortical networks.
