WebOct 16, 2024 · The SCN receives photic information from the environment and conveys this to other parts of the brain and body to synchronize all circadian clocks. The circadian clock is an endogenous oscillator that generates daily rhythms in metabolism and physiology in almost all cells via a conserved transcriptional–translational negative feedback loop. WebSCN is responsible for the control of a different aspect of the circadian rhythm and are composed of spatially-specific neurons (Moore et al. 2002).
