Circadian Clock in Neurospora

Circadian rhythms are endogenous biological programs that time metabolic and/or behavioral events to occur at optimal phases of the daily cycle. Although these rhythms parallel environmental cycles of light and dark, they are not simply a reaction to environmental fluctuations, but are generated by an endogenous timekeeping mechanism called the circadian clock. The ability of the clock to persist in the absence of environmental cues provides internal temporal organization so that rhythmic activities can occur at characteristic times during the circadian cycle (Ref.1).

The circadian clock has been conceptualized as a series of three components: an entrainment pathway that transmits environmental (usually light) signals to the timekeeping apparatus; a timekeeping apparatus, or oscillator , which operates in the absence of environmental cues [...]
