Abstract

ABSTRACTA study was made of the skin potential (SP), skin resistance (SR), and sweating of the cat's foot pad. Since many of the variables studied had previously been investigated in humans, comparable data were obtained. The characteristics of SP and SR of the cat are similar to those of humans, except that in cats, SP responses have a shorter latency than SR responses, and variation of the SP basal potential resulting from induction of a voltage between the SP electrodes has no effect on the amplitude or wave form of SP responses. Dissociation produced by arterial occlusion and procaine injection around the nerve suggest that SP responses of the cat are innervated by different nerve fibers than those which lead to the sweat glands.
