What is the arrangement of cones and rods in the retina?
The 6 million cones are concentrated toward the center, and the 120 million rods are in the periphery of the retina.
In the fovea, located centrally within the macula, each cone is served by a single ganglion cell, resulting in very high resolution.
In the periphery, many rods project to a single ganglion cell, giving high sensitivity but lower resolution.
