Question

Quizplus · Accepted Answer

Ganglion cells are most sensitive to changes in light in their receptive fields. The receptive fields have a center and a surround area. Light directed to the center of an on-center ganglion cell's receptive field will produce the highest number of action potentials. This is because an on-center ganglion cell is activated by light falling on its center and inhibited by light falling on its surround.
