Summary

Axonal anterograde degeneration after ablation of different leg segments of the spiderCupiennius salei was traced using LM-and EM-methods. The pattern of degeneration seen in cross sections of the leg nerves close to their entry into the subesophageal ganglion shows a somatotopic organization of afferents within the leg nerves coming from different leg segments. All afferents run through the ventral part of the nerve.
