Note.—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.
† For the tongue movements, the bilateral representations in the left and right hemispheres are shown.
