What Does GSR Mean?
GSR stands for “galvanic skin resistance,” sometimes called galvanic skin response. The electrical resistance of the skin, measured between two fingertips or other convenient points on the body, has been used by psychologists as an indication of nervous system activity for over 65 years. The first instruments for this purpose used an early form of electric meter called a galvanometer, after the Italian scientist Luigi Galvani. Hence, the instrument became known as a “psychogalvanometer,” and the change in skin resistance was simply called “GSR.”
