[Electrodiffusion model of a nerve impulse].

Electrodiffusion equations are deduced which describe the formation of the action potential in the axone. It is suggested that the membrane dividing internal and external axone electrolytes after being stimulated with an electric impulse returns after some time to the initial "closed" state. It is shown that the overshut of the action potential takes place due to non-linear profile distortion of the shock wave of electrical field tension vector created by the movement of sodium and potassium ions through the membrane of the axone.
