Opponent color ganglion cells that respond to blue light by increasing their rate of firing will respond to red light by (increasing/decreasing)their rate of firing.White light will cause a/an (increase/decrease/no change)in the firing rate of these cells.

Question

Quizplus · Accepted Answer

Opponent color ganglion cells respond to color contrasts, so they will decrease their rate of firing in response to a color that is opposite to the one they are sensitive to. Therefore, they will decrease their rate of firing in response to red light (which is opposite to blue light). White light contains all colors, so it will stimulate both the blue and red opponent color ganglion cells, resulting in no net change in their firing rate.
