Abstract in brief

Melanopsin-containing retinal ganglion cells (RGCs) are responsible for detecting light signals that entrain the circadian rhythm in the brain's suprachiasmatic nucleus (SCN), and they do not require rod or cone cells for this function.
Melanopsin is a visual pigment found in a specific subset of RGCs, present in their cell bodies, dendrites, and axons, and is likely the molecule that makes these cells photosensitive.
These melanopsin-expressing RGCs project to the SCN and other brain areas, and their intrinsic photosensitivity suggests they play a key role in non-image-forming visual functions like regulating the circadian clock and the pupillary light reflex.]
