Abstract
The Goldman, Henderson, and Planck junction potential equations can be used to describe the potential across the resting giant squid axon. These equations are used to calculate the relative Na, K, and Cl permeabilities of the squid axon using the experimental measurements of Hodgkin and Katz. The equations all provide excellent agreement with the observed data and yield similar permeability values.
