Amputation disrupts not only the peripheral nervous system but also central structures of the brain. While the brain is able to adapt and compensate for injury in certain conditions, in amputees the traumatic event prevents adaptive cortical changes. A group of scientists reports adaptive plastic changes in an amputee's brain following implantation of multielectrode arrays inside peripheral nerves.

Their results are available in the current issue of Restorative Neurology and Neuroscience.

"We found that a neurally-interfaced hand prosthesis re-established communication between the central and peripheral nervous systems, not only restructuring the areas directly responsible for motor control but also their functional balance within the bi-hemispheric system necessary for motor control," says lead investigator Camillo Porcaro, PhD, of the Institute of Neuroscience, Newcastle University, Medical School, Newcastle upon Tyne, UK and the Institute of Cognitive Sciences and Technologies (ISTC) -- National Research Council (CNR).
