Skin potential activity in rats, cats, and primates (including man): a phylogenetic point of view.
With rats, cats, nonhuman primates, and humans serving as subjects, skin potential activity was measured under waking conditions. In good agreement with the findings of previous workers, skin potential response waveform was always monophasic negative in rats and cats, but in humans it took three forms. By contrast, it was always monophasic positive in simian nonhuman primates, although prosimiae gave monophasic negative waves. A skin potential level-skin potential response relationship could not be observed in any subject except humans. From these results, an attempt was made to relate skin potential activity to the peripheral mechanism involved in these species on the basis of a phylogenetic point of view.
