用视网膜电图（ERG）闪烁光度法测定了普通黑猩猩的光谱敏感性。26只黑猩猩中的每一只在中长波长上显示出实质性的和近似相等的适应性变化，这意味着M-和L-视锥色素中不存在任何显著的多态性变化。如从ERG测量推断的，黑猩猩的S-视锥色素具有约430 nm的光谱峰，将黑猩猩的光谱敏感性测量结果与从同等测试的正常人三色视者获得的测量结果进行比较。这两个物种的光谱敏感性非常相似，黑猩猩对短波长光的敏感性略高于人类受试者，对长波长光的敏感性略低于人类受试者。曲线拟合分析表明，黑猩猩透镜中的光谱过滤可能低于人类透镜中的光谱过滤。黑猩猩的L/M锥比率较低。版权所有（C）1996 Elsevier Science Ltd.
The spectral sensitivity of the common chimpanzee (Pan troglodytes) was measured with electroretinogram (ERG) flicker photometry. Chromatic adaptation conditions were used to establish the presence of S-, M- and L-cone pigments, Each of 26 chimpanzees showed substantial and approximately equivalent adaptational changes over the middle and long wavelengths implying an absence of any significant polymorphic variations in the M- and L-cone pigments, As inferred from ERG measurements, the S-cone pigment of the chimpanzee has a spectral peak of about 430 nm, Chimpanzee spectral sensitivity measurements were compared to those obtained from equivalently tested normal human trichromats, The spectral sensitivity of the two species is very similar, chimpanzees being slightly more sensitive to short wavelength lights and slightly less sensitive to long wavelength lights than human subjects, Curve-fitting analyses suggest that spectral filtering may be lower in the chimpanzee lens than it is in the human lens, and that the L/M cone ratio is lower in the chimpanzee.
