During continuous conduction, local currents depolarize adjacent areas of membrane so that action potentials continue to form along the membrane. This type of conduction occurs in unmyelinated axons where action potentials can propagate from one node of Ranvier to the next, continuously depolarizing the membrane. This is in contrast to saltatory conduction, which occurs in myelinated axons and involves action potentials jumping from one node of Ranvier to the next without depolarizing the intervening membrane.
