A prosthesis is an articial device typically used to replace (keyword!) a missing body part, the next step is to control these devices directly through the nervous system. Scientist are now making progress on neural interfacing, that is, implanting a microelectrode array chip in the path of a severed nerve. The nerve will regenerate through multiple holes on the chip. The chip is capable of recording from and stimulating peripheral nerves.
Though most research is still preliminary, the future of such interfacing is to provide a direct interface to prosthitcs and to also create a direct human-computer interface.
