Daily and seasonal variation in the spectral composition of light exposure in humans.

Chronobiology international - 1 Jul 2009

Thorne Helen C, Jones Kay H, Peters Stuart P, Archer Simon N, Dijk Derk-Jan

Abstract excerpt

Light is considered the most potent synchronizer of the human circadian system and exerts many other non-image-forming effects, including those that affect brain function. These effects are mediated in part by intrinsically photosensitive retinal ganglion cells that express the photopigment melan...
