Mammalian circadian rhythms are controlled by endogenous biological oscillators, including
a master clock located in the hypothalamic suprachiasmatic nuclei (SCN). Since the period …

▪ Abstract In mammals, a master circadian “clock” resides in the suprachiasmatic nuclei
(SCN) of the anterior hypothalamus. The SCN clock is composed of multiple, single-cell …

The treatment of cultured rat-1 fibroblasts or H35 hepatoma cells with high concentrations of
serum induces the circadian expression of various genes whose transcription also oscillates …

The accumulation of adenosine is strongly correlated with the need for sleep and the
detection of sleep pressure is antagonised by caffeine. Caffeine also affects the circadian …

The circadian rhythms are daily oscillations in various biological processes that are
regulated by an endogenous clock. Disruption of these rhythms has been associated with …

The primary mammalian circadian clock resides in the suprachiasmatic nucleus (SCN), a
recipient of dense retinohypothalamic innervation. In its most basic form, the circadian …

The brain's biological clock, which, in mammals, is located in the suprachiasmatic nucleus
(SCN), generates circadian rhythms in behaviour and physiology. These biological rhythms …

Biological rhythms are driven in mammals by a central circadian clock located in the
suprachiasmatic nucleus (SCN). Light-induced phase shifting of this clock is correlated with …

Within the suprachiasmatic nucleus (SCN) of the mammalian hypothalamus is a circadian
pacemaker that functions as a clock. Its endogenous period is adjusted to the external 24-h …

The mammalian circadian clock resides in neurons of the hypothalamic suprachiasmatic
nucleus (SCN). Light entrains phase resetting of the clock using the retino-hypothalamic …
