Circadian Science

Scientists learn about circadian rhythms by studying humans or by using organisms with similar biological clock genes, including fruit flies and mice. ... Scientists also study organisms with irregular circadian rhythms to identify which genetic components of biological clocks may be broken.

1.06 Non-Photic Influences on the Circadian Timing System

By now you appreciate the powerful effect of light input on circadian rhythms. However, further studies showed that the inner clock can also respond...

1.05 The Spectrum of Light for Activating the Circadian Clock Response

The spectrum of visible light spans the range of violet to blue to green to yellow to orange and red—short to long wavelengths.  When...

1.04 The Eye as Light Transducer to the Circadian Clock: Melanopsin as a Circadian Phototransducer

We mentioned before, in Part II (Locating the Circadian Clock in the Brain), that the neural fibers that travel from the eye into the...

1.03 The Effect of Timing of Light Exposure on Circadian Rhythms (Entrainment and Phase-Shifting)

Perhaps the biggest puzzle researchers faced, once they had verified that the inner clock’s cycle differed from the earth’s rotational cycle, was how exposure...

1.02 Locating the Circadian Clock in the Brain

The properties of the inner clock—its free-run under constant lighting or darkness, its entrained response to light-dark cycles—were initially understood at the level of...

1.01 Origins of the Understanding of the Circadian Timing System and Its Free-Running Clock

The amazing field of chronobiology has recently expanded to include applications of its discoveries to treatment (chronotherapy). Nevertheless, chronobiology has its roots in strict...
