Photoreceptors in the retina are highly specialized neurons with photosensitive molecules in
the outer segment that transform light into chemical and electrical signals, and these signals …

The visual process begins with the absorption of photons by photopigments of cone and rod
photoreceptors in the retina. In this process, the signal is first amplified by a cyclic guanosine …
