Coordination in the dynamics of the brain as inferred from EEG analysis.
The present study observed the coordination between cortical areas during no task conditions as well as for the pathological condition of epilepsy, by application of the phase synchronization technique to the EEG signal in a multichannel recording. The index obtained from the phase entrainment investigation was properly scaled by a novel method to take into account the effect of nearest neighbor interactions. This scaled index was analyzed temporally to learn about the behavior of regional interactions in time. The results obtained not only corroborate earlier known results, but also give deeper insight into actual brain functioning.
