Action spectrum for light-induced melatonin suppression measured in healthy adults
Brainard GC, Hanifin JP, Greeson JM, et al. (2001) · The Journal of Neuroscience
Nighttime monochromatic light exposures across 420 to 600 nm produced an action spectrum peaking at 446 to 477 nm, which the authors reported as evidence for a novel non-rod, non-cone circadian photoreceptor in the human eye.
What they studied
72 healthy adults, 627 melatonin suppression tests
What they found
Nighttime monochromatic light exposures across 420 to 600 nm produced an action spectrum peaking at 446 to 477 nm, which the authors reported as evidence for a novel non-rod, non-cone circadian photoreceptor in the human eye.
