Opponent neurons found in the ______ provide physiological support for the opponent-process theory.
A) retina only
B) LGN only
C) superior colliculus only
D) both the retina and LGN

Question

Quizplus · Accepted Answer

The opponent-process theory proposes that the visual system has three pairs of opponent colors (red-green, blue-yellow, and black-white) and opponent neurons in the retina and LGN provide physiological evidence for this theory. These cells respond in an opposing manner to different wavelengths of light and are responsible for encoding information about color and brightness. The superior colliculus is not directly involved in color processing and its neurons do not demonstrate opponent processing, so it is not a good choice.
