Double-opponent cells are ______.
A)neurons that are excited by one color but multiplied when combined with another color
B)neurons that have a center, which is excited by one color, and a surround, which is inhibited by the opposite of that color
C)neurons that are excited by the input from rods, but not by inputs from cones
D)neurons that have a center, which is excited by one color and inhibited by its opposite, while in the surround, the pattern is reversed

Question

Quizplus · Accepted Answer

Double-opponent cells have a center-surround receptive field with opposing colors. In the center, the cell is excited by one color and inhibited by its opposite, while in the surround, the pattern is reversed. This allows cells to detect edges and create contrast between colors, aiding in color perception. Choice A is incorrect because it describes simple cells, not double-opponent cells. Choice B describes center-surround cells, but not specifically double-opponent cells. Choice C is incorrect because double-opponent cells respond to inputs from both rods and cones.
