The experiment was designed to determine a stable basis on which the GSR curve is formed. A theoretical model of a simple GSR has been proposed, with a description of its basic properties. Two dimensions of this model within which the GSR curve is plotted, are differentiated; time and value dimension A stable temporal scheme of GSR development was determined, where a ratio division of selected time sectors (active measurement points) has its base in the logarithm of the natural number "e". Certain practical consequences for its application in psychophysiological experiments have been deduced from the theoretical GSR curve. The discussion also bears on the need of an elucidation of the significance of GSR within the frame of reference of man's psychophysiological unit.
