tokens: After nerve injury , the nociceptive responses through type I neurons , which are polymodal C-fibers and drive NK1-receptor mechanisms in spinal pain transmission , were completely lost , but without changes in type II ones , which are polymodal C-fibers and drive NMDA receptor mechanisms , while type III ones , which are capsaicin-insensitive ( possibly A-fibers ) and drive NMDA-receptor mechanisms , were markedly enhanced .
