Abstract
Purpose was to determine whether our developed electrophysiological technique (Momose and Saito, 2002) using visually evoked potential (VEP) is effective for determining the color discrimination threshold in human. Both VEP and psychophysical color matching measurement were applied to three normal volunteers, and their correlation and sensitivity were investigated. Colors on the MacAdam ellipse were selected for stimulus. Threshold determined by VEP was well correlated with psychophysical measure (r=0.88 and 0.75 in two subjects), and was about 24 times higher than psychophysical ones. VEP measurement was done within much shorter time (30 min.) than psychophysical method (3 hours). VEP determined color discrimination threshold can be effective for the human color vision testing.
