[Pathways of nociceptive information transmission from different parts of the skin on cat paws].
Nociceptive reactions for damage and week actions on hairless and hairy skin was studied in acute experiments on cats. The damage stimulation of the hairless skin did not result in nociceptive reflexes, and in the case of hairy skin it always did. Using a cross-correlation method, some quantitative characteristics of afferent impulse discharges in the nerve plantaris of the cat were obtained under exposure damage and weak stimuli on the hairy and hairless skin. The afferent flow from the hairy skin has the C-afferent activity whereas in the case of hairless skin this activity was not observed. Peripheral coding of nociceptive signals under the damage action on pads of the cat is, obviously, impossible due to the absence of the C-afferent system in this kind of the hairless skin.
