Synchronization Analysis in EEG and MEG
Synchronization Analysis in EEG and MEG
This chapter describes the phase synchrony analysis in electoencephalography or magnetoencephalography data. It defines synchronization generally to be the adjustment of rhythms of self-sustained oscillating systems caused by their interaction. The chapter deals with the most-used techniques for assessing synchronization among brain regions which are distant from one another, and suggests that long-distance synchronization of human brain rhythms serves to functionally integrate distant neural populations into large-scale networks. The analysis of phase locking specializes functional connectivity to a particular form which is independent of oscillatory amplitude, namely that of oscillatory synchronization.
