Compare two visual stimuli, one that would result in an activation of an opponent-processing ganglion cell for color processing and one that would result in an inhibition of the same ganglion cell.
What will be an ideal response?
Looking at a red heart would activate the red cones, which would, in turn, activate the red-green ganglion cells, signaling the color "red" to the brain. In contrast, looking at a green apple would stimulate the green cones, which would, in turn, inhibit the red-green ganglion cell, signaling the color "green" to the brain.
