Extended Data Fig. 4: Dermatomal activation by electrodes located at different vertebrae levels for Participant 2 and Participant 3.
The left image shows the expected dermatomal innervation in the leg22. In the right, the horizontal bars indicate different dermatomes and the white ovals indicate the approximate electrode position that evoked sensations in that dermatome with respect to the vertebrae level. Participant 1 had substantial lead migration across weeks, making it challenging to precisely define the location of the electrodes with respect to vertebrae levels, so we have not included those results.
