Intrinsically photosensitive retinal ganglion cells, also called photosensitive retinal ganglion cells, or melanopsin-containing retinal ganglion cells, are a type of neuron in the retina of the mamma

Cone cells or cones are photoreceptor cells in the retina of the vertebrate eye. Cones are active in daylight conditions and enable photopic vision, as opposed to rod cells, which are active in dim li

…a type of neuron in the retina of the mammalian eye. The presence of an additional photoreceptor was first suspected in 1927 when mice lacking rod and cone cells still responded to changing light levels through pupil constriction; this suggested that rods and cones are not the only light-sensitive tissue. However…
