Abstract
Melatonin may regulate circadian activity in the suprachiasmatic nucleus (SCN) through high affinity receptors.
- The suprachiasmatic nucleus (SCN) is a central circadian pacemaker in mammals.
- SCN has its own intrinsic rhythm and is influenced by light and certain chemicals.
- Melatonin, produced by the pineal gland, is regulated by the SCN.
- Melatonin activates specific signaling pathways that affect SCN activity.
- The influence of melatonin on SCN regulation is time-sensitive.
