The Role of the Circulation in Measurements of Skin Conductivity

Summary.— Measurements of skin conductivity using silver disc and multiplint electrodes have been described. Comparisons with skin temperature measurements using thermistor probes have been made, and a parallel between the two parameters demonstrated. A connection between skin conductivity and blood flow was suggested, and confirmed by the effects on conductivity of exercise and the intradermal injection of adrenaline and histamine under the electrode site. The implications of this are discussed and a possible role of such measurements in the clinic is mentioned.
