WebPermeability changes associated with prolonged action potentials have been analyzed in procaine-treated crayfish abdominal muscle fibers. The effect of external Ca indicates … WebThe action potential is a brief change of the membrane potential, caused by opening of channels that allow cations (especially Na +) to enter the neuron, followed by an outward flow of K + ions. A net influx of cations reduces the membrane potential by making the interior less negative.
