Dynamics of Intermittent Synchronization of Neural Activity
Neural activity of individual neurons and neuronal populations frequently exhibits synchronized dynamics. This synchronization has been related to a number of functions and dysfunctions of the brain. Synchronization of neural activity in the brain is rarely perfect. Rather, it exhibits intermittent dynamics, where episodes of synchrony are interspersed with episodes of non-synchronized activity. We review the recent developments in the studies of the intermittent neural synchrony with the focus on the analysis of the desynchronized dynamics. The application of the new analysis techniques to recordings of neural activity in different experiments suggests that different neural systems in the brain favor dynamics with short (although potentially numerous) desynchronization intervals. We further discuss the utility of this analysis in the study of neural systems and the potential functional significance of short desynchronization dynamics in the brain.
