Interfacing electronics with the nervous system

As part of a joint basic technology programme with members of the Nanoscience centre and Physics of Medicine we are developing a novel device with which it is possible to make electrical recordings from nerve fibres. In damaged nerves, the fibres can grow through the interface, or nerves can be dissected and the teased strands inserted. Using this device we have developed a strategy for restoring control to the bladder following spinal cord injury. A device for bladder control in dogs with spinal cord injury is now in clinical use.
