Electrodennal activity refers to electrical changes across the skin in areas of the body that are psychologically responsive. The eccrine sweat glands are the primary detenninant of electrodennal activity, and these are psychologically active especially on the palms of the hands and the soles of the feet. As a matter of convenience, electrodennal activity is most often recorded from the palms. Over the years, the electrodennal response has been known as the psychogalvanic reflex, the galvanic skin response, the skin resistance response, the skin conductance response, and the skin potential...
