Time–frequency maps of event-related signal power changes. Time–frequency maps of event-related signal power changes. A, Predominant α and β ERD in left sensorimotor cortex during preparation for right-hand movement and thereafter. B, ERD/ERS in the right auditory cortex before and after sound making. C, Time courses of group mean β ERD/ERS in the frequency band of 16–18 Hz, showing significant increase in β ERD. D, Permutation test for the differences between ERD/ERS maps in B revealed significances for β oscillations 200–300 ms after sound onset. E, Spectral power in the baseline interval preceding the stimulus in the passive listening conditions. Thick lines denote time intervals of significant differences between presound-making and postsound-making conditions at α = 0.01. Bernhard Ross et al. J.
