[The differentiation of color signals by the frog retina].
Multidimensional scaling of principal interstimulus chromatic differences, measured by the value of ERG reaction of the frog retina allowed to construct a model reflecting colour differentiating function of this level. It follows from this model that the frog retina has colour differentiating characteristics answering standard requirements of trichromatic vision. Colour-opponent system of frog is represented by the functions of red-green and blue-yellow opponentness compared with the analogous functions obtained for man.
