Sensory Motor Transformations in Human Cortex

About this trial

This trial is recruiting individuals with chronic cervical (neck area) spinal cord injuries to test the safety and effectiveness of an implanted device to control a computer or other device by thoughts. Researchers also want to see if the device (Neuroport Array) provides participants with sensory feedback. The study involves implantation of three electrode arrays into the surface of the brain over areas that control reach and grasp movement, as well as sensory awareness of the hand and fingers. This brain wave information can be used to train participants to move a computer cursor or robotic arm. A sensory awareness array can be used to provide stimulation to sensory circuits in the brain in order to simulate touch and “feel” of an object. It is hoped that the addition of sensory feedback will allow better control of simulated movements. Participants will receive surgery to implant the electrodes and subsequent training sessions up to 3-5 times a week. The study lasts one year after implantation.
