Circadian rhythms have been observed in behavioral and physiological activities of living
things exposed to the natural 24 h light-darkness cycle. Interestingly, even under constant …

Modern imaging techniques allow the monitoring of circadian rhythms of single cells.
Coupling between these single cellular circadian oscillators can generate coherent periodic …

Aging is an inevitable life process which is accelerated by lifestyle and environmental
factors. It is an irreversible accretion of molecular and cellular damage associated with …

Retinal photoreceptor outer segments (POS) are renewed daily through phagocytosis by the
adjacent retinal pigment epithelial (RPE) monolayer. Phagocytosis is mainly driven by the …

Circadian rhythms of physiological and behavioral activities are regulated by a central clock.
This clock is located in the bilaterally symmetrical suprachiasmatic nucleus (SCN) of …

The main function of the principal clock located in the suprachiasmatic nucleus (SCN) of
mammals is synchronizing the body rhythms to the 24 h light-dark cycle. Additionally, the …

In mammals, an endogenous clock located in the suprachiasmatic nucleus (SCN),
synchronizes physiological and biological rhythms to the environmental light–dark cycle. In …

In both diurnal and nocturnal species, the neurons in the suprachiasmatic nucleus (SCN)
generate a daily pattern in which the impulse frequency peaks at midday and is lowest …

Diversity is omnipresent in natural and synthetic extended systems, the phenomenon of
diversity-induced resonance (DIR), wherein a moderate degree of the diversity can provoke …

Mammals not only can be synchronized to the natural 24-h light-dark cycle, but also to a
cycle with a non-24-h period. The range of the period of the external cycle, for which the …
