The process by which light hits the back of the retina (i.e. the pigmented layer) and causes a chain of events that results in action potentials travelling down the optic nerve to the central nervous system has several steps. Please explain those steps in your own words. Be sure to discuss the components of the photopigments, the conformational change that one of those components undergoes in light vs. dark, the cellular signaling that the photopigment initiates, and how three neuron types daisy-chain onto each other to elicit action potentials in the optic nerve when exposed to light.
