Neural synchrony would be a crucial mechanism of emerging a dynamic cortical network for various cognitive processing. The neural synchrony was often observed in the scalp EEG measure for a speech perception. The performance of auditory perception also depends on a phase of scalp EEG appearing prior to the stimulus input. Together with these previous studies, we hypothesized that the interplay of the EEG phase between pre- and post-stimulus presentation determines an optimal condition to emerge a cortical network for the speech perception. To verify our hypothesis, we measured the scalp EEG during a speech perception task. The results showed that the EEG phase locking during the speech perception was manipulated by the pre-stimulus EEG phase. The appropriate cortical network for the speech processing could be emerged by the optimal EEG phase before the pre-stimulus input. |
