Research Abstract

We have investigated a functional role of the intrinsically photosensitive retinal ganglion cells(ipRGCs) to the non-image forming and image-forming pathways. It was found that the ipRGCs contribute to the steady-state pupillary control mechanism. The manuscript for a study of the contribution on the image-forming pathway is in press.
