Current—voltage curve of sodium channels and concentration dependence of sodium permeability in frog skin

1. The inward facing membranes of in vitro frog skin epithelium were depolarized with solutions of high K concentration. The electrical properties of the epithelium are then expected to be governed by the outward facing, Na‐selective membrane.
