A person’s conscious sensation of touch (somatosensation) is essential to motor function. Control and fine movement of prosthetic limbs are inherently impaired because patients are limited to visual sensory feedback. Somatosensation is a key component of achieving neurorestoration of motor function. Flesher and colleagues1 recently reported that intracortical microstimulation of the primary somatosensory cortex (S1) evoked subjective somatosensation, potentially restoring a conscious discriminatory touch experience, and may improve performance of cortically controlled limb prostheses.
