[Activity in the myelinated fibers of a cat cutaneous nerve in response to cooling].
The afferent activation in cat cutaneous nerve fibres in response to cooling was analyzed using the collision method and the method improving the signal-to-noise ratio in the antidromic action potential neurogram. It was found that the nerve fibres of groups Adelta1 and Adelta2 were activated under cutaneous receptors cooling. The activity of a small group of nerve fibres with conduction velocity 13.0--7.5 m/s was inhibited in response to cooling. A group of "mixed" fibres inhibited mainly its activity, but only an insignificant part of these fibres activated in response to cutaneous receptors cooling.
