Current flows outward through the membrane under the cathode and inward through the membrane under the anode. Thus, membrane potential is depolarized under the cathode and hyperpolarized under the anode. The anodal and cathodal electrotonic potentials are shown in Figure b (below). These electronic potentials are recorded by positioning the exploring electrode in the immediate vicinity of the anode and then the cathode....
