For people with cervical spinal cord injury or brainstem stroke, the signals from the motor cortex have been “disconnected” from the limb. One of the goals of implanted neural interfaces is to provide natural, real-time control of assistive devices that would be helpful to people with paralysis or limb loss. Recent work has markedly advanced the field of prosthetics for people who have had one or both arms amputated due to trauma or vascular disease. Additionally, there are safe and useful robotic limbs that can be attached to a wheelchair and used much in the same way the arm and hand was used prior to injury to the nervous system. We are working to evaluate the feasibility of using the brain signals directly related to intended movement of the hand
to enable easier and more complex control over these advanced prosthetic limbs and assistive robotic devices. Also, we are working to develop systems that we hope will allow people with paralysis to reanimate their own limbs simply by thinking about the movement of that limb.
