Summary
This research demonstrates that intrinsically photosensitive retinal ganglion cells (ipRGCs) containing melanopsin play a significant role in the pupillary light reflex in both human and non-human primates, extending earlier findings from rodent studies. Understanding the primate-specific contribution of ipRGCs to the PLR has implications for designing lighting systems that appropriately engage non-visual photoreceptive pathways.
Key Findings
- ipRGCs contribute significantly to the pupillary light reflex (PLR) in primates, consistent with prior findings in rodents.
- Results extend the known role of melanopsin-containing retinal ganglion cells from rodent models to primate visual systems, suggesting evolutionary conservation of this non-visual photoreceptive function.
