NIH funded research

If you've tried to search for journal articles and read them online, you know that a large number of scientific journals today are difficult to access, except from within an institution that subscribes. The following bibliography includes the NIH-published versions of some of the work done at Brigham and Women's Hospital (Harvard Medical School).

Exposure to Room Light before Bedtime Suppresses Melatonin Onset and Shortens Melatonin Duration in Humans

The human circadian system adapts to prior photic history

High sensitivity of the human circadian melatonin rhythm to resetting by short wavelength light.

Effect of Light on Human Circadian Physiology

Suppression of melatonin secretion in some blind patients by exposure to bright light.

A phase response curve to single bright light pulses in human subjects
