The proportions of sympathetic postganglionic and unmyelinated afferent axons in normal and regenerated cat sural nerves.
Electrophysiological experiments have been carried out to see if the proportions of sympathetic postganglionic and unmyelinated afferent axons in a cutaneous nerve were changed after injury and regeneration. It seemed possible that an alteration in the relative numbers of the two groups of axons could contribute to the aetiology of reflex sympathetic dystrophy, but the experiments provided no evidence for such a change. There were, however, signs of a decrease in axon numbers in the regenerated nerves.
