Abstract

Many aspects of human physiology and behavior are dominated by 24 h rhythms that have a major impact on our health and well-being. The daily light-dark cycle plays the primary role in synchronizing these rhythms with the 24 h day. The properties of light that determine the efficacy of its circadian phase-resetting effects include the timing, intensity, duration, pattern, wavelength, and history of exposure. Major advances have been made in understanding how light is detected by the eye to reset circadian rhythms. A novel photoreceptor system has been discovered that mediates circadian photic responses that is anatomically and functionally distinct from the visual system. © 2009 Elsevier Ltd All rights reserved.
