Physiological support for opponent color representation comes from:
A) the discovery of two types of cones in the fish retina that responded in similar ways to different wavelengths.
B) the observation that people sorted a stack of cards into four piles of colors, rather than three.
C) measurements of neurons in the ventral geniculate nucleus of rats that responded to color in an opponent fashion.
D) confirmation of the existence of neural circuits involved in the opponent color representation process.

Question

Quizplus · Accepted Answer

The correct answer is supported by the understanding that physiological evidence for opponent color representation includes the identification of neural circuits that specifically process colors in an opponent manner, reflecting the theory that colors are perceived not as independent entities but in terms of opposing pairs (e.g., red vs. green, blue vs. yellow). This is a fundamental aspect of how the visual system processes color information.
