Abstract

ABSTRACTIn order to clarify the mechanism of skin potential level (SPL) measured on the foot pads of cats, 5 acute animals were used without any anesthetic drug. Spontaneous skin potential responses (SPRs) immediately disappeared after peripheral denervation, but SPL remained the same negative level as before. Moreover, this level reduced in negativity after death, gradually passing zero potential toward positivity. The existence of SPL after peripheral denervation or death suggests that a major portion of SPL can be conceived as an energy‐consuming bioelectrical potential having no relationship to central nervous system activation as considered previously.
