Quiz #11

Question 1

True or false: Rod photoreceptors detect color and cones photoreceptors detect low levels of light?

Answer 1

False: cones detect color and rods detect light.

Question 2

True or false: rods are heavily concentrated in the fovea of the retina and there are few of them in the periphery.

Question 3

True or false: Input from many photoreceptors is combined into a single ganglion cell in the retina.

Answer 3

True

Question 4

True or false: Antagonistic visual receptive fields highlight areas in our visual fields that have little contact.

Answer 4

False: our visual fields have a lot contact.

Question 5

True or false: The trichromatic theory of color has been disproven and replaced by the opponent-process theory.

Answer 5
