Annual Review of Physiology, 2001
▪ Abstract The circadian clock is intrinsically linked to the daily cycle of day and night. A capacity for entrainment to light-dark cycles has proven to be a universal feature of the clock in all organisms examined. Here we review a wealth of recent advances that reveal more about the light input mechanisms by which the circadian clock is set to the

Neurology, 1994
Prompted by the observation that a fellow medical student sneezed at about the same time in class every morning, we recorded the time of each of the 118 sneezes she made on 69 days over a 6.5-month period. Analysis of the sneeze times with the goodness-of-fit test revealed a highly nonuniform distribution (p < 0.0001) with a significantly increased ...

In this chapter, we will discuss mathematical models of the master circadian rhythm in the suprachiasmatic nucleus of the hypothalamus with a particular emphasis on models that incorporate the effect of light on circadian phase resetting and melatonin suppression.

Hormone Research in Paediatrics, 1994
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 ...

Circadian biomarkers, circadian genes and bipolar disorders
Journal of Physiology-Paris, 2011Bipolar disorders are associated with circadian deregulations both during acute mood episodes and during euthymic periods, suggesting that these circadian rhythms may represent trait markers of the disease. Several arguments demonstrate that deregulations of circadian rhythms may be part of the pathophysiology of bipolar disorders.

The American Journal of Medicine, 1988
All forms of life, from the simplest cells to the most complex organisms, show periodicity in some of their biologic activities and functions. The most common of these rhythmic events are those that we refer to as "circadian" (circa, around; dias, day).

Circadian Carbamazepine Toxicity
Epilepsia, 1994Summary: Owing to marked fluctuations in plasma con‐centrations, circadian CNS toxicity (maximum in the early afternoon) occurred in a 69‐year‐old female patient being treated with an instant‐release formulation of carbamazepine (CBZ). The neurologic syndrome was reversible after administration of the same daily dose as sustained‐release formulation ...
