No apparent effect of lumbar dorsal rhizotomy performed simultaneously with the peripheral nerve injury, has been revealed on the triggering of regeneration of sensitive nerve fibers. Re-innervation of the foot skin by either decentralized regeneration of nerve fibers or those sustaining their connections with the central nervous system (CNS), has been shown to start 30 days after surgery. Using the recording of impulse activity of a single nerve fibre, the mechanical thresholds of decentralized regenerating receptors were found to be significantly higher as compared to the thresholds of the regenerating receptors sustaining their connections with the CNS. The findings suggest that afferent nerve fibers and mechanical receptors formed on the periphery, continue functioning after decentralization and sustain their regenerative capacity after injury. However, in marked contrast, the decrease in sensitivity of regenerating receptors is more pronounced. |
