Alpha and beta spectrotemporal clusters and their corresponding source localizations. (a) A schematic representation of the experimental paradigm. (b) Sensor space time-frequency representation of non-phase-locked spectrotemporal modulations. Red and blue colors represent percentage increase and decrease in power with respect to the baseline period. The black contours represent the time-frequency regions that are consistent across participants as obtained from the cluster-based permutation test. Source localization of the beta (c) and alpha (d) power decrease clusters. The black contours represent the cortical vertices that are consistent across participants as obtained from the cluster-based permutation test.
