Question

The ________ states that there are three kinds of cones in the retina, each of which responds primarily to a specific range of wavelengths.

Answer 1

Step-by-step explanation:

For visual processing on the retina, trichromatic theory applies: the cones are responsive to three different wavelengths that represent red, blue, and green. But once the signal moves past the retina on its way to the brain, the cells respond in a way consistent with opponent-process theory.
