Starting from known spectral properties of visual photopigments and photoreceptors, a mathematical construction of neural response functions to visual stimuli is obtained. Included in this is a somewhat general derivation of the univariance principle. Temporal dependence of response on stimulus is included in the formulation. Special attention is given to the case of flash stimuli and their resulting spectral sensitivities. This formulation is applied to certain physiological spectral sensitivity measurements that are at variance with known spectrophometric results. An analysis of the data in these cases suggests that they correspond to "pseudo-pigments" arising from the neural interaction of several photopigments. The method of analysis is constructive and identifies the gamma-max's of the interacting photopigments. These are found to be in good agreement with existing spectrophotometric measurements.
从视觉光色素和光感受器的已知光谱特性出发，得出了对视觉刺激的神经反应函数的数学构建。其中包括单变量原理的某种一般性推导。反应对刺激的时间依赖性包含在公式中。特别关注闪光刺激的情况及其产生的光谱敏感性。该公式应用于某些与已知分光光度测量结果不一致的生理光谱敏感性测量。对这些情况下的数据进行分析表明，它们对应于几种光色素神经相互作用产生的“假色素”。分析方法具有建设性，可识别相互作用光色素的最大γ值。发现这些值与现有的分光光度测量结果高度吻合。
