Quizplus · Accepted Answer

A bipolar cell with a center-on, surround-off receptive field will respond to light stimulation in the center of the field by increasing its rate of firing. However, shining light on the entire receptive field will not change the cell's rate of firing because there is no change in the balance of excitation and inhibition between the center and surround regions.
