Primates have central retinal region {fovea}| that tracks motions and detects self-motion. Retinal periphery detects spatial orientation. Fovea contains 10,000 neurons in a two-degree circle. Fovea has no rods. Fovea center has no short-wavelength cones. Fovea has patches of only medium-wavelength cones or only long-wavelength cones. Fovea has no blood vessels, which pass around fovea.
