Rapid Effect of Sodium Cyanide and Dinitrophenol on Mammalian Nerve

Abstract
Strips of rat nerve from dorsal roots were immersed in solutions containing sodium cyanide and α-dinitrophenol. The inhibitors extinguish the action potential of such strips within minutes. The rapid action on mammalian nerve is contrasted with the slow effect of inhibitors on amphibian and invertebrate nerve.
