Experimental setup. Recording and stimulation electrodes were wrapped around the explanted sciatic nerve of a frog. These were submerged in a physiological Ringer solution. Two electrodes were placed at opposite ends of the container and powered with a sinusoidal signal of 200 m V _{p p} at a frequency of 200 Hz. The tied extremities of the nerve (not shown) were attached to maintain the nerve extended and submerged.
