Like most organisms, we have developed an internal time keeping system that drives daily rhythms in metabolism, physiology and behavior, and allows us to optimally anticipate to the momentum of the day. At the basis of circadian timekeeping lies an intracellular molecular oscillator in which a set of clock genes cyclically regulate their own expression with an approximate (circa) 24-h (dies) periodicity. The mammalian circadian system consists of a light-entrainable master clo...
