Response to an itch-producing substance in cat. II. Cutaneous receptor populations with unmyelinated axons

Within the sampled population of cutaneous unmyelinated afferent neurons ( n = 94), only the C-polymodal nociceptor population was reactive to the pruritogen cowhage. Of 62 C-polymodal neurons tested, 11 were unresponsive to cowhage. No C-polymodal neurons were more responsive to inactive, than to a...
