The brainweb: Phase synchronization and large-scale integration

Francisco Varela1, Jean-Philippe Lachaux1, Eugenio Rodriguez2 & Jacques Martinerie1  About the authors

The emergence of a unified cognitive moment relies on the coordination of scattered mosaics of functionally specialized brain regions. Here we review the mechanisms of large-scale integration that counterbalance the distributed anatomical and functional organization of brain activity to enable the emergence of coherent behaviour and cognition. Although the mechanisms involved in large-scale integration are still largely unknown, we argue that the most plausible candidate is the formation of dynamic links mediated by synchrony over multiple frequency bands.
