The figure shows a typical response of an on-center ganglion cell, which responds with an increase in action potentials when light is shone in the center of its receptive field and a decrease in action potentials when light is shone in the surrounding area or periphery of its receptive field. This is evident by the peak in the graph when light is presented in the center of the receptive field and the trough when light is presented in the periphery.
