When the spinal cord is damaged, the connection between the brain and some part of the body may be lost.
To restore this connection, researches are considering either:
Repairing the damaged area so that the spinal cord works again.
Bypassing the spinal cord by connecting the brain directly to the affected part of the body. This is done by implants in the brain connected directly to electrodes in the muscles creating a new circuit in parallel.
My question is has there been any attempt to bypass only the damaged part of the spinal cord? To create a bridge over the damaged tissue?
