B)lateral inhibition in the visual cortex.
C)calculation of differences in the firing rates of three types of retinal cells.
D)competition between three types of rods and three types of cones.

Question

Quizplus · Accepted Answer

The opponent-process theory of color vision proposes that our perception of color is based on the calculation of differences in the firing rates of three types of cones in the retina: one that responds best to short wavelengths (blue), one that responds best to medium wavelengths (green), and one that responds best to long wavelengths (red). These cones send information to the brain in a way that creates opposing pairs: red versus green, blue versus yellow, and black versus white. This theory doesn't involve lateral inhibition on the retina or in the visual cortex, or competition between different types of rods and cones.
