Fig. 6

Decode output and raster plot during a 5-DOF target touching task for S4. Each figure shows the target position (solid black line) and decode output (dashed and colored line) on the top 5 lines. DOFs displayed in order from the top are thumb flex, index flex, middle flex, ring flex, and wrist flex/extend. Displayed below in black hash marks is the raster plot from 19 electrodes shown (15 from the median nerve array and 4 from the ulnar array). a thumb flexion targets b index finger flexion targets, c middle finger flexion targets, d ring finger targets, e thumb-index pinch target. Note that the subject was able to perform this combination movement despite training only single single-DOF training movements. f wrist flexion and extension targets
