How about checking into the use of optogenetics to build a universal, minimally invasive neural interface? We have optogenetic treatments that make nerve cells responsive to and emissive of light. Can we treat nerve cells to transmit and receive light over a fiber optics, letting us bridge gaps in existing neural paths? something like that night go a long way to healing all sorts of neural degenerative disease, and possibly deal with paralysis as well. Perhaps eventually something along the lines of plug and play hardware for humans, if you can come up with some sort of universal spec for it.
