Fig. 6 |. Projected fields for nerve stimulation.

The electrical stimulation of the residual somatosensory nerves of an amputee evokes localized and stable percepts on the missing hand. Stimulation through different electrodes located on the median (blue), ulnar (green), and radial (red) nerves over the course of two months led to consistent perceived sensations on the phantom hand (the locations are indicated by the coloured patches).
