Italian scientists placed two segments of spinal cord on a bed of carbon nanotubes, separated by 300 microns, and saw them knit together. And, with signal analysis, they were able to prove that an electrical connection was achieved (and not achieved when the nanotube support was removed). Rodent experiments showed that implanted nanotubes were well tolerated, as they must be for prosthetics in the human central and peripheral nervous systems. MORE
