Axotomy produced an increase in the spike width and a decrease in amplitude of the afterhyperpolarization which followed the action potential in C-cells of bullfrog sympathetic ganglia. Although no change in B-cell conduction velocity was noted, C-cell conduction velocity increased significantly and approached that of B-cells. This change may reflect a process of dedifferentiation prior to the initiation of regrowth following axotomy.
