Note.—Comparisons of the COGs and the percentage of overlapping volumes for the finger, hand, wrist, and elbow movements in contralateral M1. Data are from the single-subject analysis. Numbers of subjects were as follows: 24 for the hand, fingers, wrist, and elbow experiments and 22 for the tongue and foot experiments.
* Data are the mean ± SD.
