The best characterization of receptive fields in retinal ganglion cells that respond best to light-dark contrast is that for a cell that responds to light it has no response to light in its center on field for a cell that responds to light it has a strong response to light in the surround field for a cell that responds to light it has a strong response to light in its center on field for a cell that responds to light it has a weak response to light in its center on field
