Event-related spectral perturbation (ERSP) in pressing tasks for Monkey C. (a) Z scored time-domain signal (left) and time‒frequency map (right) for a single representative electrode, averaged across all pressing trials and aligned with the onset of movement (time = 0; red vertical line). (b) Session-wise mean beta-band (13–30 Hz, left) and high-gamma band (60–90 Hz, right) ERSPs, averaged across electrodes; shaded areas denoting the 95% confidence interval (CI) across electrodes. (c) Topographic distribution of the beta-band (left) and high-gamma band (right) ERSP changes relative to the baseline, averaged across recording sessions and expressed in decibels (dB). The orientation is as shown in Fig. 1c; black- and red-outlined electrodes denote task-relevant and exemplar channels, respectively. (d) Topographic distribution of the –log₁₀(p) values derived from Spearman’s rank correlation between the daily mean beta-band (left) or high-gamma band ERSP (right) and the daily mean movement speed. The black-circled electrodes indicate task-relevant sites.
