FIG 1. Activation in contralateral M1 (arrows) displayed in axial sections for one subject in the first session. The right side of the sections corresponds to the left hemisphere, and the numbers in the color bar correspond to t values.

A and B, The fingers (A) and hand (B) are in almost identical locations (z plane, +58).

C and D, The wrist (C) and elbow (D) representations are located more medially, superior and posterior along the course of M1 (z plane, +59 and +61, respectively).

E and F, Note the considerable overlap of activated volumes within the arm and the clear separation of the foot (E) and tongue (F) (z plane, +66 and +28, respectively).
