Abstract

Performance of efficient and precise movement requires the proper planning of motor parameters as well as the integration of sensory feedback. This study tests the hypothesis that the frontal components of the median nerve somatosensory-evoked potentials are differentially modulated, depending on (i) the stage of motor preparation and (ii) the moving limb. Participants were instructed to make intermittent voluntary contractions with either their right or left hands while receiving median nerve stimulation to the right wrist only. The results indicate that the frontal N30 demonstrated a significant increase in amplitude during the execution, but not the preparation, of a movement contralateral to median nerve stimulation. These data have implications for interhemispheric control of sensory information within the primary and premotor cortices.
