How body clocks work together in mammals

Abstract
Circadian rhythms, which operate on a 24-hour cycle, are regulated by a master clock in the brain.
- Biological time is measured in cycles ranging from milliseconds to years.
- Circadian rhythms are generated by a complex molecular mechanism present in various tissues.
- Independent tissue-specific rhythms are coordinated by the brain's master clock.
- Light input from the environment influences the synchronization of these rhythms.
