If nerves are basically just signal-carrying wires, why cant they just be reconnected with copper wire in the case of injury?

Question

Edit: Or gold. Or something else electrically conductive but biologically safe.

In: Biology

Answer 1

Safest answer is probably that copper wires wouldn’t really be able to flex or move as the body does so using them as a replacement wouldn’t work. Not to mention the actual biological repercussions of putting copper wires into the body. If you can even shave copper down to the size it ywould need to be to become a nerve.
