A New Animal Model for Developing a Somatosensory Neural Interface for Prosthetic Limbs
Abstract
During the 12-month funding period, we completed a total of 7 acute experiments, with the goal of developing a technique for using multichannel microstimulation to activate several distinct groups of primary afferent neurons in the dorsal root ganglia (aim 1). The utility of multichannel microstimulation is for the encoding of information in the spatiotemporal patter of stimulation applied to the afferents (aim 2). To the effectiveness of afferent microstimulation, we recorded evoked neural activity in the somatosensory cortex during microstimulation with patterns that varied in 1) amplitude (stimulus current), 2) location (various channels within the DRG electrode array) and 3) rate (the frequency of microstimulation pulses applied to each DRG.
