While recording from a bipolar cell with an off-center on-surround receptive field, you observe a hyperpolarization in your cell. The stimulus that most likely triggered this response is light that covered

D) the entire receptive field.

Question

Bipolar cells with off-center on-surround receptive fields hyperpolarize when light covers the center of their receptive field. This is because the center is inhibitory (off-center), and light activation leads to a decrease in the cell's activity, resulting in hyperpolarization.
