Role of the Dorsal Root Ganglion in Neuropathic Pain

Prof. Marshall Devor gives an informative lecture on the nature of neuropathic pain, and how it differs in both physiology and treatment from nociceptive pain. He presents compelling evidence that shows that neuropathic pain is mostly generated by the cells within the DRG and not from axonal injury. He discusses a surprising alternative to the widely accepted cause of radiculopathy (sciatica in this case) that physician encounter on a daily basis.
