Retinal Ganglion Cells
Retinal ganglion cells are neurons located in the retina that receive visual information from photoreceptors and send it to the brain via the optic nerve.
Melanopsin
A photopigment found in specialized photosensitive retinal ganglion cells, important for regulating circadian rhythms and pupil constriction in response to light.
Suprachiasmatic Nucleus
A tiny region in the brain's hypothalamus responsible for controlling circadian rhythms by regulating melatonin production, affecting sleep and wakefulness.
