Abstract
IN a recent communication in Nature, Ling and Gerard1 state that support for the membrane potential of nerve and muscle being a diffusion potential is afforded by the rectilinear relation between the logarithm of external potassium concentration and the measured membrane potential according to the well-known Nernst equation. For a single fibre of the frog sartorius this value is reported to be 95 millivolts, which is the approximate theoretical value.
