TL;DR: It is argued that the most plausible candidate is the formation of dynamic links mediated by synchrony over multiple frequency bands.

TL;DR: It is argued that whereas long‐scale effects do reflect cognitive processing, short‐scale synchronies are likely to be due to volume conduction, and ways to separate such conduction effects from true signal synchrony are discussed.

TL;DR: In this article, the authors show that only face perception induces a long-distance pattern of synchronization, corresponding to the moment of perception itself and to the ensuing motor response, and suggest that this desynchronization reflects a process of active uncoupling of the underlying neural ensembles that is necessary to proceed from one cognitive state to another.

TL;DR: A direct comparison between these two methods for quantification of phase synchrony between neuronal signals on three signal sets is conducted, and it is concluded that they are fundamentally equivalent for the study of neuroelectrical signals.

TL;DR: This paper introduces a new method, single-trial phase locking statistics (S-PLS), to estimate phase locking in single trials of brain signals between two electrodes, and compares these results with those provided by PLS and shows that they are qualitatively very similar, although S-PLs provides better discrimination of synchronic episodes.
