A squid axon membrane separating two solutions of the same chemical composition can exhibit electrical excitability. Passage of a constant inward current through such a membrane induces oscillatory responses in membrane potential. The salts of cobalt, manganese, nickel, and barium are suitable as a constituent in the solution for demonstrating this oscillatory response.
