研究人员对恒河猴视网膜中央 10 度的 211 个颜色对立神经节细胞进行了研究，以确定它们从不同视锥细胞机制接收的输入。在中性和彩色背景存在下的光谱敏感性测量表明，24% 的细胞似乎接收来自所有三种锥体机制的输入。 2. 在 3% 的细胞中，红色敏感视锥细胞机制与蓝色和绿色敏感视锥细胞机制相反。在 18% 的细胞中，蓝色敏感视锥细胞机制与绿色和红色敏感视锥细胞机制相反。在 3% 的细胞中，绿色敏感视锥细胞机制与蓝色和红色敏感视锥细胞机制相反。 3. 在接受对手绿色和红色敏感视锥细胞输入的 12% 细胞中，可以检测到来自红色敏感视锥细胞机制的 β 带的响应，并将其与蓝色敏感视锥细胞输入区分开来。 4.所有接受蓝色敏感视锥细胞输入的细胞似乎都是三色的。具有三色输入的细胞的视网膜分布和具有β带反应的细胞的视网膜分布似乎与所考虑的视网膜区域中蓝色敏感视锥细胞的可用性平行。 5. 结果表明，猕猴视觉系统中的三色相互作用始于视网膜。
Two hundred and eleven colour‐opponent ganglion cells were studied in the central 10 degrees of the retina of the rhesus monkey, to determine the inputs which they were receiving from different cone mechanisms. Spectral‐sensitivity measurements in the presence of neutral and coloured back‐grounds showed that 24% of these cells appeared to receive input from all three cone mechanisms. 2. In 3% of the cells, the red‐sensitive cone mechanism opposed the blue‐ and green‐sensitive ones. In 18% of the cells, the blue‐sensitive cone mechanism opposed the green‐ and red‐sensitive ones. In 3% of the cells, the green‐sensitive cone mechanism opposed the blue‐ and red‐sensitive ones. 3. In 12% of the cells receiving opponent green‐ and red‐sensitive cone inputs, responses from the beta‐band of the red‐sensitive cone mechanism could be detected and distinguished from blue‐sensitive cone input. 4. All cells receiving blue‐sensitive cone input appeared to be trichromatic. The retinal distribution of cells with trichromatic input and that of cells with beta‐band responses seemed to parallel the availability of blue‐sensitive cones in the retinal area being considered. 5. The results indicate that trichromatic interactions in the macaque visual system begin in the retina.
