Effect of continuous current. A continuous firing causes a train of pulses that decrease in amplitude but increase in frequency when the applied current increases. The higher frequency causes the pulses to fire before the action potential fully recovers. At the higher current the amplitude decreases significantly between the first and second action potential. Subsequent action potentials show a smaller decline. The reduced action potential is associated with lower...
