WebWhen you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.”. Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision. WebAs an electrical signal propagates along a given nerve, it can be detected at a succession of locations along the length of the nerve and its direction and speed of propagation can be determined by detecting the times of appearance and the polarities of the electrical signal at two (e.g., closely) spaced apart locations and determining how much ...
