Behavioral discrimination tests and electroretinogram (ERG) flicker photometry were used to measure spectral sensitivity and to define the spectral mechanisms of the guinea pig (Cavia porcellus). Results from these 2 approaches converge to indicate that guinea pig retinas contain rods with peak sensitivity of about 494 nm and 2 classes of cone having peak sensitivities of about 429 nm and 529 nm. The presence of 2 classes of cones suggests a retinal basis for a color vision capacity. Behavioral tests of color vision were conducted that verified this prediction: Guinea pigs have dichromatic color vision with a spectral neutral point centered at about 480 nm. The cone pigment complement of the guinea pig is different from that known to characterize other rodents.
采用行为辨别测试和视网膜电图（ERG）闪烁光度法来测量豚鼠（豚鼠属）的光谱敏感性并确定其光谱机制。这两种方法的结果一致表明，豚鼠视网膜含有峰值敏感性约为494纳米的视杆细胞以及两类峰值敏感性分别约为429纳米和529纳米的视锥细胞。两类视锥细胞的存在表明了其具有色觉能力的视网膜基础。进行了色觉行为测试，证实了这一预测：豚鼠具有二色性色觉，光谱中性点约为480纳米。豚鼠的视锥色素组成与已知的其他啮齿动物不同。
