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.
