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: Recent findings demonstrating human gamma-frequency activity associated with attention and memory in both sensory and non-sensory areas are discussed.

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.
