Abstract
IN an earlier paper it was shown that addition of small concentrations of choline ion to bathing solutions which already contain cæsium significantly reduces the resting membrane potential of frog sartorius muscles1. The work recorded here is an extension of this investigation, and is concerned with the following questions : (a) Are the combined effects of cæsium and choline on the membrane potential reversible ? (b) To what extent does potassium affect the cæsium–choline interaction ? (c) Does the entire muscle cell surface participate in the cæsium–choline interaction ?
