that that produce temporal windows for communication [42, 43]. The alpha oscillations exercise a strong inhibitory influence on both spike timing and firing rate, and thus the pulsed inhibition by alpha oscillation plays an important role in the extended sensorimotor system [44]. Characteristic changes in ERD and ERS power in schizophrenia during the classic oddball task may be caused by dysfunction in a flexible pattern of coherence that defines a flexible communication structure related to synchronization of a large population of neurons.
