Afferent impulses from skin receptors in response to a jet of air

The colliding impulse method was used to investigate afferent impulsation in different types of fibers of the cutaneous nerves innervating the hairy skin on the medial surface of a cat's paw. It was shown that a change in the intensity of the acting stimulus caused a change in the structure of the afferent flow. An increase in the strength of the jet of air caused an increase in the number of active fibers and in the frequency of the afferent impulsation and it led to the excitation of other types of fibers also.
