Abstrakt		A novel method of measuring SCR (Skin Conductance Response) is presented. Skin conductance response is any sudden decrease in skin resistance in excess of few hundred ohms, followed by a recovery. SCR can be triggered by an external stimuli (like a loud tone or a mild electric shock). There are also "spontaneous" SCRs, which are not obviously correlated with any external stimuli. Skin conductance response is often accompanied by a SPR (Skin Potential Response), a sudden change in skin potential. These two responses look similar and share the same frequency space. When the SCR is measured by a constant current, the result is some superposition of both these responses, thereby yielding only a qualitative result. It is easy to measure only the potential by simply not applying any current. But to measure only the resistance, skin potential has to be dealt with and removed from the measurement. It can be filtered out only if it can be shifted in the frequency space, away from the position of SCR. This paper explains how this was accomplished. The prototype was also used to assess the decrease of the spontaneous SCR frequency due to a treatment condition (transcendental meditation).
