Photographs showing device implantation in the patients in Cases 1 and 2. Left: Two nonpenetrating microwire arrays (1-mm spacing) were implanted over the right primary motor cortex in the first patient. Channels 1–16 are over the hand area (orange wire), and channels 17–32 are over the arm area (green wire). Right: A single 30-channel array (2-mm spacing) was implanted over the left primary motor cortex hand and arm area in the second patient.
