    abstract = {Most nonprimate mammals possess dichromatic ( ” red–green color blind”) color vision based on short-wavelength-sensitive (S) and medium/long-wavelength-sensitive ({ML}) cone photoreceptor classes. However, the neural pathways carrying signals underlying the primitive  ” blue–yellow” axis of color vision in nonprimate mammals are largely unexplored. Here, we have characterized a population of color opponent ({blue-ON}) cells in recordings from the dorsal lateral geniculate nucleus of anesthetized cats. We found five points of similarity to previous descriptions of primate {blue-ON} cells. First, cat {blue-ON} cells receive {ON}-type excitation from S-cones, and {OFF}-type excitation from {ML}-cones. We found no {blue-OFF} cells. Second, the S- and {ML}-cone-driven receptive field regions of cat {blue-ON} cells are closely matched in size, consistent with specialization for detecting color contrast. Third, the receptive field center diameter of cat {blue-ON} cells is approximately three times larger than the center diameter of non-color opponent receptive fields at any eccentricity. Fourth, S- and {ML}-cones contribute weak surround inhibition to cat {blue-ON} cells. These data show that {blue-ON} receptive fields in cats are functionally very similar to {blue-ON} type receptive fields previously described in macaque and marmoset monkeys. Finally, cat {blue-ON} cells are found in the same layers as W-cells, which are thought to be homologous to the primate koniocellular system. Based on these data, we suggest that cat {blue-ON} cells are part of a  ” blue–yellow” color opponent system that is the evolutionary homolog of the {blue-ON} division of the koniocellular pathway in primates.},

Most non-primate mammals do not have specialized photoreceptors for the medium-wavelength band. Most primates do.

Neural responses in LGN to short and medium-to-long wavelengths of light are antagonistic in rodents and cats (in certain cells).

Buzás et al. found blue-ON-type cells in the cat LGN, but no blue-OFF cells.

Blue-ON-type cells in primate and cat LGN have large receptive fields
