The development … WitrynaRods and cones are two types of photoreceptors in the eye. Both are specialized nerves that convert light into neural impulses, but they differ in number, location, and function. Rods are more numerous, located in the periphery of the eye, and good for detecting light in general. Cones are concentrated near the fovea, responsible for …
