Can we restore natural perception with electrical stimulation?

Abstract

A useful tactile somatosensory prosthesis must (i) evoke somatosensory percepts in limited body regions, (ii) provide graded sensation, (iii) have reproducibility and persistence, (iv) provide the perception of slip and pressure, and (v) provide proprioception. With thalamic stimulation we have been able to produce 3 of these 5.
