• An improved double sucrose gap method employing four thin rubber membranes was introduced. By using preparations of radular protractor from a mollusc, Rapana thomasiana, it was possible to record the stable membrane potential for long periods of time and monophasic action potentials of about 20 mV. Furthermore, upon application of current, cell membranes within a central chamber of 1.8 mm in width appeared to be polarized or depolarized uniformly over a wide voltage range. Membrane resistance could also be measured, and it was found that membrane resistance during acetylcholine (ACh) depolarization was reduced to about 30% of normal. The ionic mechanisms of ACh depolarization were considered to be due mainly to the increase in Na^+ and Cl^- conductances of the membrane.
