Response cue induced changes in beta-band activity after spectral stratification for the EMG power. A, Pooled t spectra of the power difference between cue left and right conditions during the stimulus interval, averaged across significant clusters of sensors (p < 0.05, corrected), as highlighted in the topography (inset). Red line, Left hemisphere cluster. Blue line, Right hemisphere cluster. Source analysis results of the response cue induced modulation in beta-band (20 Hz) activity (B). Visual stimulus induced changes in beta-band activity for the cue left condition (C, E) and the cue right condition (D, F), suggestive of a cue-dependent asymmetric decrease in beta-band oscillatory activity. Pooled t spectra were averaged across the highlighted sensors in the corresponding topographies (C, D). Source analysis results of stimulus-induced changes in oscillatory activity at 20 Hz (E, F).
