Sensory afferent impulses originate from dorsal root ganglia as well as from the periphery in normal and nerve injured rats
PD Wall, M Devor - Pain, 1983 - Elsevier
Single units were recorded in dorsal roots or in the sciatic nerve of anaesthetised rats. It was
shown by making sections, by stimulation and by collision that some ongoing nerve
impulses were originating from the dorsal root ganglia and not from the central or peripheral
ends of the axons. In a sample of 2731 intact or acutely sectioned myelinated sensory fibres,
4.75%±3.7% contained impulses generated within the dorsal root ganglia. In 2555 axons
sectioned in the periphery 2–109 days before, this percentage rose to 8.6%±4.8%. There …
