Examples of multi-joint/multi-body part movements evoked after LT-ICMS in M1. A, Movement evoked from site 98 of Case 15-01 (see Figure 1-1). This movement involved an elevation of the entire arm plus forearm supination and elbow flexion, which brought the hand to the mouth. B, Movement evoked from site 73 of Case 15–02 (see Figure 2-1). Stimulation at this site evoked movements of the face (e.g., mouth closing; cheeks elevating) accompanied by shoulder elevation. C, Movement evoked from site 16 of Case 15–02 (see Figure 2-1) involved an arm elevation, elbow flexion, and digit extension. D, Movements evoked from site 68 of Case 15-01 (see Figure 1-1) involved both the forelimb and hindlimb. Drawings were obtained from video frames taken from two different moments: (1) before ICMS (i.e., body in the starting position; gray lines); and (2) at the apex of the movement during ICMS (black lines).
