The Instantaneous Visual Threshold after Light Adaptation

Abstract

Blanchard's measurements of the instantaneous visual threshold following light adaptation to different intensities and colors fit directly into the pattern of the duplicity theory which separates vertebrate vision into cone and rod functions. Moreover, the numerical values of the measurements and the precise form of their relations conform to the mathematical predictions from a reversible photochemical system previously used for describing other properties of vision and photoreception. || ABSTRACT AUTHORS: Auth. summ
