She said most current thinking on physiological response is that it’s not just melanopsin and the intrinsically photoreceptive retinal ganglion cells (ipRGCs) of the non-visual system that impact physiology. The visual-centric rods and cones play a role as well, although researchers are still working to understand the interaction.
