7-7 色覚のマルチチャンネル機構における非対称性 Asymmetry in multichannel mechanism in color vision

The multichannel mechanism in color vision was experimentally studied. Psychophysical measurements were carried out using DOG(Difference of Gaussians) test patterns of the combination of dual colors such as red-green and blue-yellow. Difference in numbers and spatial characteristics of channel mechanisms were observed by reversing the colors in the center and the surrounding of the test patterns.
