The Suprachiasmatic Nucleus Generated Rhythm in Blood Glucose
The daily rhythm in feeding activity in mammals, as driven by the biological clock, largely determines the daily fluctuations in basal concentrations of glucose and insulin. To investigate a possible direct impact of the suprachiasmatic nucleus (SCN) on these parameters, we subjected intact rats and SCN-lesioned rats to a fasting regimen of 36h, or to a scheduled feeding regimen of six identica...
متن کاملSuprachiasmatic nucleus
So what’s the fuss? In mammals, it is the site of an endogenous pacemaker that regulates 24 hour, circadian rhythmicity, synchronizing the phases and periods of a host of behavioral, physiological, and hormonal rhythms to the environmental light–dark cycle. The SCN also appears to function as a seasonal clock underlying the measurement of daylength. The SCN was first implicated as a master cloc...
متن کاملCircadian Gene Expression in the Suprachiasmatic Nucleus 901 Circadian Gene Expression in the Suprachiasmatic Nucleus
Regulated expression of a core set of clock genes is the basis of circadian timekeeping in vertebrates, as in other organisms. Clock genes are defined as being necessary to generate normal circadian rhythms, near 24 h oscillations in biological processes. With the enlargement of the brain in vertebrates, control of circadian rhythms became centralized. In lower vertebrates, such as fishes, liza...
متن کاملIdentification of the suprachiasmatic nucleus in birds.
Circadian rhythms are generated by an internal biological clock. The suprachiasmatic nucleus (SCN) in the hypothalamus is known to be the dominant biological clock regulating circadian rhythms in mammals. In birds, two nuclei, the so-called medial SCN (mSCN) and the visual SCN (vSCN), have both been proposed to be the avian SCN. However, it remains an unsettled question which nuclei are homolog...
متن کاملResetting the suprachiasmatic nucleus clock.
Recent research on the cellular basis of circadian rhythmicity has stressed the importance of clock genes for the maintenance of normal rhythmicity. There have been tremendous advances in our understanding of the inter-relationships of the various genes known to generate the rhythms. We know relatively little, however, about the way animals maintain their rhythmicity under normal seasonally cha...
