The extent of regeneration of the central axonal processes of dorsal root ganglion cells was determined using anterograde horseradish peroxidase histochemistry at 1-12 weeks after dorsal root transection in adult frogs. At 4, 8 and 12 weeks axons were found to have regenerated across the dorsal root entry zone and into the spinal cord.
