Solid state physical theory of nerve impulse conduction: Elovich kinetics of axon repolarization currents.

The sodium repolarization currents of Myxicola single axons clamped at -100 mV with and without tetrodotoxin conform to the Elovich equation, which implies that in the axon, Na+ is associated with charged sites on macromolecules and water is structured, and that an activation energy barrier to conduction of Na+ exists at the axon surface.
