Biological Clocks: Who in This Place Set Up a Sundial?
How do circadian rhythms, alarm clocks and the light/dark cycle interact? The concept of social jetlag is informing our appreciation of the tensions and consequences of imposing an artificial temporal order upon our biology.
متن کاملBiological clocks.
Circadian rhythms describe biological phenomena that oscillate with an approximately 24-hour cycle. These rhythms include blood pressure, body temperature, hormone levels, the number of immune cells in blood, and the sleep-wake cycle. In this paper, we will focus on common genes between species that are responsible for determining the circadian behavior, especially some transcription factors (i...
متن کاملBiological switches and clocks.
To introduce this special issue on biological switches and clocks, we review the historical development of mathematical models of bistability and oscillations in chemical reaction networks. In the 1960s and 1970s, these models were limited to well-studied biochemical examples, such as glycolytic oscillations and cyclic AMP signalling. After the molecular genetics revolution of the 1980s, the fi...
متن کاملCircadian clocks and memory: time-place learning
Time-Place learning (TPL) refers to the ability of animals to remember important events that vary in both time and place. This ability is thought to be functional to optimize resource localization and predator avoidance in a circadian changing environment. Various studies have indicated that animals use their circadian system for TPL. However, not much is known about this specific role of the c...
متن کاملBiological clocks and ventricular tachyarrhythmias.
Sudden cardiac death (SCD) due to sustained ventricular tachyarrhythmias (VTA) remains a major public health problem because of poor understanding of the mechanisms. Initiation of VTA in animal models and in patients usually requires intense metabolic or electrical stimuli not often observed for spontaneous arrhythmias, suggesting that profound but clinically silent electrophysiological changes...
