Multiple Photoreceptors Contribute to Nonimage-forming Visual Functions Predominantly through Melanopsin-containing Retinal Ganglion Cells
Several light-sensing cells affect non-visual light responses mainly through special retinal cells containing melanopsin

Abstract
Genetic ablation of melanopsin-containing retinal ganglion cells leads to severe impairment in circadian photoentrainment and pupillary light reflex.
- Mammals can detect light for various physiological functions even without functional rod and cone photoreceptors.
- This light detection is linked to intrinsically photosensitive retinal ganglion cells that express the photopigment melanopsin.
- Rods and cones can compensate for the absence of melanopsin in nonvisual light-dependent physiological behaviors.
- The precise interactions and contributions of different photoreceptors to nonimage-forming visual functions are not fully understood.
- Image formation remains intact despite the genetic ablation of melanopsin-containing retinal ganglion cells.
