G.C.Brainard – EFFECTS OF LIGHT ON BRAIN AND BEHAVIOR
„It is obvious that light entering the eye permits the sensory capacity of vision. The human species is highly dependent on visual perception of the environment and consequently, the scientific study of vision and visual mechanisms is a centuries old endeavor. Relatively new discoveries are now leading to an expanded understanding of the role of light entering the eye – in addition to supporting vision, light has various nonvisual biological effects.“
