X rays caused a rise in excitability that lasted for not less than 4 to 5 hr in distal areas of the nerve when they were allowed to act on 8 to 9 mm lengths of frog sciatic nerve. The action potential spikes from the nerve were heightened, whether the stimuli to the distal areas were threshold, medium, or strong. This rise in excitability in distal areas went with two phases of change in the action potentials of grnstrocnemius muscle, if the muscle potentials were recorded when the nerve was stimulated in distal areas. The muscle potentials at first rose and then fell. The contractile responses also showed two phases that ran parallel; some effect spread from the irradiated area to the muscle itself. (auth)
