Question

Quizplus · Accepted Answer

On-center ganglion cells are activated by light in their center and inhibited by light in their surround. This means that they receive excitatory input from on-center bipolar cells (which respond to light in the center of their receptive field) and inhibitory input from off-center bipolar cells (which respond to light in the surround). Therefore, choice A is the best answer.
