Peripheral nerve injury in a rat model (spinal nerve ligation) of neuropathic pain triggers sprouting of sympathetic fibers in the dorsal root ganglion (DRG). This sympathetic sprouting has been suggested as an important underlying mechanism for pain behaviors. To investigate the possibility of functional interaction between sprouted sympathetic fibers and sensory neurons, the present study examined the fine morphology and structural relationship between sympathetic fibers and the DRG neurons… CONTINUE READING
