The brainweb: Phase synchronization and large-scale integration

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