When does it start ticking? Ontogenetic development of the mammalian circadian system
When the Mammal Body Clock Begins to Work During Development
AI simplified
Abstract
Circadian rhythms are governed by a central rhythm generator in the hypothalamic suprachiasmatic nucleus (SCN).
- The circadian system coordinates physiological functions with environmental cycles.
- Light synchronizes the adult circadian system, while maternal signals influence fetal and neonatal rhythms.
- The SCN controls peripheral circadian oscillators through molecular feedback loops of clock genes.
- Maturation and entrainment of the central rhythm generator and peripheral oscillators occur during development.
