Circadian rhythmicity definition
WebPhysiological processes occur in accordance with a rhythm regulated by the endogenous biological clock. This clock is programmed at the molecular level and synchronized with the daily light–dark cycle, as well as activities such as feeding, exercise, and social interactions. It consists of the core clock genes, Circadian Locomotor Output Cycles Protein Kaput … WebThe SCN is the central player in an important neural system, the circadian timing system (CTS). This article reviews the principal properties of circadian rhythms, the characteristics of circadian rhythmicity in the SCN, and the major output of the latter. The nature of the SCN in nonmammalian vertebrates is also briefly considered.
