Circadian rhythms, cardiac arrhythmias and sudden death

Frontiers in Bioscience-Landmark, 2021
The heart, like most mammalian organs, is influenced by circadian patterns. The suprachiasmatic nucleus in the hypothalamus has a key role in this influence, via various neurohumoral factors, particularly the autonomic nervous system.

Serotonin and circadian rhythms. [PDF]

Psychology & Neuroscience, 2010
All mammal behaviors and functions exhibit synchronization with environmental rhythms. This is accomplished through an internal mechanism that generates and modulates biological rhythms. The circadian timing system, responsible for this process, is formed by connected neural structures.
