Effects of External Ions on Membrane Potentials of a Crayfish Giant Axon

Abstract

Transmembrane potentials in the crayfish giant axon have been investigated as a function of the concentration of normally occurring external cations. Results have been compared with data already available for the lobster and squid giant axons. The magnitude of the action potential was shown to be a linear function of the log of the external sodium… (More)
