Quizplus · Accepted Answer

On-center cells are excited by light that falls in the center of their receptive field. This means that when light hits the center of the cell's receptive field, the cell will be activated and begin firing. However, if light falls in the periphery of the cell's receptive field, it may not be activated as strongly or at all. On-center cells are named because they have a distinct area in the center of their receptive field where they are most sensitive.
