Question

Quizplus · Accepted Answer

The opponent-process theory suggests that there are three color "pairs" (red-green, blue-yellow, black-white) and that neurons in the visual system respond in opposing ways to each member of the pair. Option B directly supports this theory by showing that some neurons are excited by green light but inhibited from firing by red light, suggesting an opponent relationship between these colors. Options A and C do not provide evidence for the opponent-process theory, and option D is incorrect because rods do contribute to color vision in low-light conditions.
