Reaction of nonmyelinated fibers of the cutaneous nerve of cats to cooling]

Combining the colliding impulses method with the methods of singling out the nerve's weak signals from the equipment noise shows that most nonmyelinated fibers of C1 and C2 groups develop impulses under cooling the cat hairy skin. In some nonmyelinated fibers of the C2 group there takes place an inhibition of spontaneous impulses in response to cooling.
