Is the Electricity in Your Body the Same as Electricity in a Wire?
In short: Wires and nerves both run on electrical charge and potential, but a wire moves electrons through metal while living tissue moves ions across cell membranes.
A 2:02 short film in the series “Photon and Brain”, narrated by intellect_voice_01.
