Photoreceptor Cells: Specialized cells that detect and transduce light. They are classified into two types based on their light reception structure, the ciliary photoreceptors and the rhabdomeric photoreceptors with Microvilli. Ciliary photoreceptor cells use Opsins that activate a Phosphodiesterase phosphodiesterase cascade. Rhabdomeric photoreceptor cells use opsins that activate a Phospholipase c cascade.

Human color vision is impressive. People with normal color vision can tell apart millions of individual hues. Most amazingly, this ability is achieved with fairly simple hardware.


Part of the power of human color vision comes from a…
