PERIPHERAL EFFECTOR MECHANISM OF GALVANIC SKIN REFLEX

Abstract

Galvanic skin response was observed in an absence of epidermis, in the existence of ingoing current flow and recorded simultaneously with impedance change. Conclusion was drawn that galvanic skin response recorded by endosomatic method is a summation of two processes: The negative process is caused by change of apparent skin resistance and the positive process is induced by electrical activity of sweat gland.
The variability of wave form with use of small electrode was recognized and a comparison of exosomatic and endosomatic method was made.
