Grand average corticomuscular coherence patterns in CTRL group estimated for each of the 3 frequency bands, alpha (8–12 Hz), beta (13–30 Hz), gamma (31–60 Hz). Ext: CMC patterns obtained for the extension movement executed with left (a) and right (b) hand. Grasp: CMC patterns obtained for the grasping movement, executed with left (c) and right (panel d) hand. The 2D body model is seen from the above: scalp with nose pointing up the top and arms in front of the participant. Only statistically significant CMC values are represented (paired t-test between task and rest trials, α = 0.05 FDR correction). The color bar codes for the CMC average value (across participants, N = 12) in the task trial
