[VHF2-3L(Invited)] The Role of Intrinsically Photosensitive Retinal Ganglion Cells in Brightness Perception
brightness, perception, ipRGCs, melanopsin
We applied psychophysical techniques to investigate the role of ipRGCs in brightness perception. The results suggest that ipRGCs play a role in acquiring absolute value of visual environmental information and in offsetting cone response. Furthermore, it was found that the contribution of ipRGCs exceeded 50% as visual stimulus intensity increased.
