In '''1843''' Emil Du Bois-Reymond, a german physiologist, was the first to describe "action potentials" of muscular contraction. He used a highly sensitive galvanometer, which contained more than 5 km of wire. Du Bios Reymond named the different waves: "o" was the stable equilibrium and he was the first to use the p, q, r and s to describe the different waves. <cite>Dubois</cite> | In '''1843''' Emil Du Bois-Reymond, a german physiologist, was the first to describe "action potentials" of muscular contraction.
