EVIDENCE FOR THE RFSTING MEMBRANE POTEN TIAL GENERATION IN THE INTERNODAL AXO LEMMA OF THE MYELINATED GIANT NERVE FIBER IN THE SHRIMP (Penaeus japonicus)

Recent electrophysiolgical studies demonstrate that the ion channels involved in the conduction of the action potential are distributed unevenly along the axolemma of vertebrate myelinated nerve fibers: the axolemma of the nodal region is rich in the voltage-dependent sodium channels but absent (in the rabbit) or poor (in the frog) in the
