Subjective time expansion with increased stimulation of intrinsically photosensitive retinal ganglion cells

Abstract Intrinsically photosensitive retinal ganglion cells (ipRGCs) contain photoreceptors that are especially sensitive to blue light. Nevertheless, how blue light and ipRGCs affect time perception remains unsolved. We used the oddball paradigm and manipulated the background light to examine whet...
