Circadian rhythms in isolated brain regions.
The suprachiasmatic nucleus (SCN) of the mammalian hypothalamus has been referred to as the master circadian pacemaker that drives daily rhythms in behavior and physiology. There is, however, evidence for extra-SCN circadian oscillators. Neural tissues cultured from rats carrying the Per-luciferase transgene were used to monitor the intrinsic Per1 expression patterns in different brain areas an...
متن کاملCircadian redox rhythms in the regulation of neuronal excitability.
Oxidation-reduction reactions are essential to life as the core mechanisms of energy transfer. A large body of evidence in recent years presents an extensive and complex network of interactions between the circadian and cellular redox systems. Recent advances show that cellular redox state undergoes a ~24-h (circadian) oscillation in most tissues and is conserved across the domains of life. In ...
متن کاملSignificance of circadian rhythms in severely brain-injured patients
OBJECTIVE To investigate the relationship between the presence of a circadian body temperature rhythm and behaviorally assessed consciousness levels in patients with disorders of consciousness (DOC; i.e., vegetative state/unresponsive wakefulness syndrome or minimally conscious state). METHODS In a cross-sectional study, we investigated the presence of circadian temperature rhythms across 6 t...
متن کاملCellular and biochemical mechanisms underlying circadian rhythms in vertebrates.
Circadian clocks organize neural processes, such as motor activities, into near 24-hour oscillations and adaptively synchronize these rhythms to the solar cycle. Recently, the first mammalian clock genes have been found. Unpredicted diversity in signaling pathways and clock-controlled gating of signals that modulate timekeeping has been discovered. A diffusible clock output has been found to co...
متن کاملCircadian rhythms.
1997 marks the 25th anniversary of the discovery of the master circadian pacemaker in mammals in the hypothalamic suprachiasmatic nucleus. Remarkable progress has been made over the last 25 years in elucidating the physiological mechanisms involved in the entrainment, generation and expression of circadian rhythms at the cellular and systems levels. The recent discovery and cloning of the first...
