À propos du système circadien chez l’homme : de l’horloge interne à la sécrétion de mélatonine
The human body clock and how it controls melatonin release
AI simplified
Abstract
Circadian rhythm desynchronization can occur due to factors like shift work, aging, and certain psychiatric conditions.
- The internal biological clock is located in the suprachiasmatic nuclei of the anterior hypothalamus.
- Clock genes and environmental factors help synchronize this clock to a 24-hour cycle.
- Disruptions to the circadian system can lead to misalignment with astronomical time.
- The circadian system includes the clock, the retinohypothalamic tract, and melatonin from the pineal gland.
- Light and melatonin have phase response curves that may aid in treating sleep circadian disorders.
