PHOTOTRANSDUCTION BY RETINAL GANGLION CELLS THAT SET THE CIRCADIAN CLOCK
David M. Berson, Felice A. Dunn, Motoharu Takao

“The utterly unexpected discovery of another set of photoreceptors in the human retina sparked not only new and interesting neural vision research, but an awakening within the lighting community of a much-heightened consciousness of what is now broadly referred to as “light and health.”  -  David L. DiLaura, FIES, LC (Leucos Vol 2 No 1 July 2005 pg 4)
