[Skin potential activity under two electrode electrolytes].

To examine whether the basal skin potential levels (BSPL) obtained from habituated and relaxed subjects are determined by a relationship between the electrode electrolyte concentration and the individual values of body fluid electrolyte, the skin potential level (SPL) and reflex (SPR) were measured with 0.06 mol NaCl agar and 0.03 mol KC1 agar as the electrode electrolytes. These electrolyte concentrations were determined in consideration of sodium and potassium concentrations in the palmar tissue. The results showed that under two electrolytes there were no significant differences in relation to SPL and SPR except for the number of SPRs. Therefore, our results support the views on the BSPL mechanism suggested by Christie and Venables (1971 a).
