The ERG of the rat, evoked by equal energy flashes of monochromatic light in the dark-adapted eye, flashes superimposed on a bright “white” background, and flashes superimposed on chromatic backgrounds, was used to construct action spectra for the rat eye. These action spectra indicate that the rat retina contains more than one spectral mechanism. While these data are inadequate for determination of the number and spectral characteristics of the underlying mechanisms, the hypothesis that the rat has a single spectral mechanism mediated by rhodopsin must be rejected.
