Question

There are two theories of color vision. The _____ theory correctly describes color vision in the retina, while the _____ theory correctly explains color vision in the ganglion cells and visual cortex

Answer 1

Color vision is explained by two theories: the trichromatic theory for the retina and the opponent-process theory for ganglion cells and the visual cortex.

Step-by-step explanation:

There are two theories of color vision. The trichromatic theory correctly describes color vision in the retina, according to which there are three types of cones in the retina that are responsive to red, blue, and green wavelengths. The opponent-process theory explains color vision in the ganglion cells and visual cortex, with the idea that colors are coded in opponent pairs, such as black-white, yellow-blue, and green-red, allowing for the experience of afterimages and the absence of certain color combinations like greenish-reds or yellowish-blues.
