Abstract
It is well known that the skin potential response (SPR) in humans took 3 or 4 waveforms. The authors previously confirmed, by contrast, that the waveforms were always monophasic positive in simian nonhuman primates, although those were always monophasic negative in prosimiae, cats, and albino rats. Both the skin potential levels (SPLs) and SPRs were recorded from the foot pad of nonanesthetized 7 adult dogs, using Ag-AgCl with 0.05M NaCl agar electrodes. It was observed that the SPLs were always negative (from -12 to -20mV) and the SPR waveforms were always monophasic negative. And both the pattern of SPLs and SPRs in dogs including the amplitude, time course, and frequency of spontaneous SPRs were similar to those recorded from cats.
