Action Spectrum for Melatonin Regulation in Humans: Evidence for a Novel Circadian Photoreceptor
Brainard GC, Hanifin JP, Greeson JM, et al. Journal of Neuroscience. 2001.
doi.org/10.1523/JNEUROSCI.21-16-06405.2001 · Finding checked against the abstract
Source details checked refers to publication information or an official source page. See the record’s limitations for incomplete extraction and the method for how to read the labels.
What the source reports
In 627 night-time melatonin suppression tests on 72 adults, wavelengths of 446 to 477 nm were the most potent, an action spectrum that pointed to a new photoreceptor rather than the rods and cones.
Design questions and applications
Design light spectrum by time of day.
Field
Light and circadian
Notes and follow-up
Added from the Corpus Desk (card brainard-2001-action) on 2026-11-09; the card finding was rewritten from the abstract. Evidence strength and translation distance not yet rated. WELL label held for review.
