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

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.
