Abstract

SCIENCE TIMES of achieving neurorestoration of motor sensory perceptions (including quality, Intracortical intensity, and location of stimuli in the function. Flesher and colleagues recently Microstimulation of reported that intracortical microstimu- hand) were monitored. The participant verbally reported the location of detected lation of the primary somatosensory cortex Human Somatosensory (S1) evoked subjective somatosensation, sensations using a map of the hand (Figure). After intracortical S1 micros- potentially restoring a conscious discrimi- Cortex Reproduces natory touch experience, and may improve timulation, the predominant sensations Touch in Spinal Cord in the hand were described as possibly performance of cortically controlled limb natural (93%), both at the skin surface and prostheses. Injury Patient below (94%), without pain (100%), and In this study, 2 microelectrode as a mild pressure coming from a specific person’s conscious sensation of arrays were implanted in the primary hand location (67%). His description touch (somatosensation) is essential somatosensory cortex (S1), covering the of predominant sensations as “possibly to motor function. Control and postcentral gyrus areas associated with the index and little fingers, in a 28-year-old natural” on the naturalness scale (ranging fine movement of prosthetic limbs are from totally unnatural to totally natural) inherently impaired because patients tetraplegic man
