Electrical responses of the human eye to changes in saturation of the stimulating light.
Previous studies on color vision using the electroretinogram or the evoked potential have concentrated only on brightness and hue but not on the saturation of color. In the present investigation patterns of alternate stripes of a highly saturated color and a totally desaturated color (= white) of equal brightness were presented in the pattern-reversal mode. It can be demonstrated that the reading obtained is in agreement with psychophysical saturation scale data of earlier investigators.
