The body’s daily rhythm system in the mammal’s retina
Updated
Abstract
The master pacemaker controlling 24-hour rhythms in mammals is found in the suprachiasmatic nuclei of the hypothalamus.
- Circadian rhythms are generated internally by organisms rather than solely responding to environmental changes.
- The circadian clock influences diverse functions including sleep, food intake, body temperature, heart rate, and hormone release.
- The retinal circadian clock is identified as the first extra-SCN circadian oscillator in mammals.
- Physiological, cellular, and molecular rhythms in the retina are believed to be regulated by a network of circadian clocks.
