Paradoxical Sleep Suppresses Immediate Early Gene Expression in the Rodent Suprachiasmatic Nuclei

Frontiers in Neurology, 2010
Light stimulates neuronal activity with subsequent expression of the protein product of the immediate early gene, c-fos, in the Suprachiasmatic Nuclei (SCN). Non-photic stimuli is also thought to modulate activity within the SCN.

Circadian and Metabolic Effects of Light: Implications in Weight Homeostasis and Health [PDF]

, 2017
Daily interactions between the hypothalamic circadian clock at the suprachiasmatic nucleus (SCN) and peripheral circadian oscillators regulate physiology and metabolism to set temporal variations in homeostatic regulation.

Circadian rhythms and hormonal homeostasis: Pathophysiological implications [PDF]

, 2017
Over recent years, a deeper comprehension of the molecular mechanisms that control biological clocks and circadian rhythms has been achieved. In fact, many studies have contributed to unravelling the importance of the molecular clock for the regulation ...

Mathematical model of the interaction between the dorsal and ventral regions of the suprachiasmatic nucleus of rats

Sleep Science, 2010
Background and objective: In mammals, the main biological clock that is synchronized by light is located in the suprachiasmatic nucleus of the hypothalamus, which can be divided into two distinct regions: the ventrolateral and the ...

Voluntary exercise can strengthen the circadian system in aged mice [PDF]

, 2013
Consistent daily rhythms are important to healthy aging according to studies linking disrupted circadian rhythms with negative health impacts. We studied the effects of age and exercise on baseline circadian rhythms and on the circadian system's ability ...

Modulating effect of irisin on the functional state of inhibitory afferent inputs to the suprachiasmatic nucleus from the arcuate nucleus [PDF]

BIO Web of Conferences
In vitro experiments on viable hypothalamic slices of male Wistar rats, the modulating effect of the myokine irisin on the parameters of inhibitory responses of neurons in the suprachiasmatic nucleus to stimulation of the arcuate nucleus was studied.

Acute knockdown of Kv4.1 regulates repetitive firing rates and clock gene expression in the suprachiasmatic nucleus and daily rhythms in locomotor behavior [PDF]

, 2017
Rapidly activating and inactivating A-type K+currents (IA) encoded by Kv4.2 and Kv4.3 pore-forming (α) subunits of the Kv4 subfamily are key regulators of neuronal excitability.

The Visually Related Posterior Pretectal Nucleus in the Non-Percomorph Teleost Osteoglossum bicirrhosum Projects to the Hypothalamus [PDF]

, 1991
This study was done to elucidate the ancestral (plesiomorphic) condition for visual pathways to the hypothalamus in teleost fishes. Three patterns of pretectal organization can be discerned morphologically and histochemically in teleosts. Their taxonomic

Alterations of clock gene RNA expression in brain Regions of a triple transgenic model of Alzheimer's Disease [PDF]

, 2017
A disruption to circadian rhythmicity and the sleep/wake cycle constitutes a major feature of Alzheimer's disease (AD). The maintenance of circadian rhythmicity is regulated by endogenous clock genes and a number of external Zeitgebers, including light ...

The Hypothalamus of the Beaked Whales: The Paraventricular, Supraoptic, and Suprachiasmatic Nuclei

Biology, 2023
The hypothalamus is the body’s control coordinating center. It is responsible for maintaining the body’s homeostasis by directly influencing the autonomic nervous system or managing hormones. Beaked whales are the longest divers among cetaceans and their
