Abstract: Department of Physiology Faculty of Medicine Hokkaido University Received for publication October 13 1955. SUMMARY On the GSR curves obtained by the current method the influences of the strength of electric current and of local skin temperature and their regional differences over the body were investigated by means of electromagnetic oscilIograph (Vibrator F). As for the GSR curves obtained by the potential method the wave forms were studied using an 8-channel electroencephalograph. Experiments were carried out both on men and cats in the summer season. 1) The GSR curves recorded by the current method showed increase in amplitude reduction in latent time and prolongation in top-time with increase of the electric current in the circuit. 2) The summation curves gotten by the current method which were induced by stimulation of the hypothalamus or of the lumbar ganglia were very high and top-headed. They showed a conspicuous contrast to the not so high flat-topped potential curves induced in the same way by the Richter et al. and Patton. 3) It was demonstrated that local skin temperature could change remarkably the latent time and top-time of GSR curves and could control even the appearance of GSR. 4) As for the regional differences of GSR curves it was ascertained that the GSR of the palm differed essentially from that of the back of hand at least in three experimental results. 5) After elaborate investigations it has been concluded that bi- or triphasic potential curves can actually appear from the palm and that such wave forms are influenced distinctly by local skin temperature. ___MH
