Compare the fovea and periphery in terms of receptive fields and their properties.
What will be an ideal response?
Receptive fields in the fovea have a one-to-one correspondence between cones and retinal ganglion cells. This allows for acute vision. In the periphery, however, there is a many-photoreceptors-to-one-retinal-ganglion-cell correspondence, resulting in less precise peripheral vision that covers a larger area.
