Voluntary nerve signals from severed mammalian nerves: long-term recordings

An electrode unit capable of detecting voluntarily elicited nerve signals for prolonged periods of time has been developed and tested. The electrode unit has been implanted around the distal ends of severed sciatic and peroneal nerves in rabbits. This electrode may prove suitable for implantation in human amputees for the purpose of recording neural control signals to activate prostheses with many degrees of freedom.
