Key findings

  • Synchronization of oscillations is proposed as a mechanism regulating communication in brain networks
  • Methodological challenges had long limited noninvasive study of interactions between brain areas
  • Advances in M/EEG source reconstruction and clustering support complete phase-interaction mapping
  • Synchronization appears robust and behaviorally significant in task-relevant cortical networks

A review of how synchronized neuronal oscillations may coordinate activity across distributed brain areas into coherent cognitive operations. The authors explain that technical problems long limited the study of interactions between brain areas with noninvasive magnetoencephalography and EEG (M/EEG), but recent advances in source reconstruction and clustering now allow complete mapping of phase interactions. They conclude that synchronization is a robust, behaviorally significant feature of task-relevant cortical networks that may bind distributed processing into coherent cognitive states.
