Electrophysiological recording setup, recording sites, and maps of different digit segments for the four squirrel monkeys (SMs). a Schematic diagram of the spinal cord inserted with four electrodes, each with 16 channels that are 150 μm apart. b Sample photograph of the four inserted electrodes in SM-Ara. c Cytochrome oxidase stain used to verify electrode penetrations of the spinal cord by identifying the electrolytic lesion. Exposed spinal cord with mapped digit regions (color dots) and recording sites (black asterisks) for (d) SM-Ara, (e) SM-Lego, (f) SM-Gua, and (g) SM-Bus. Scale bars represent 1 mm. Shaded white regions are estimated segments of the spinal cord
