Mismatch between perceived family and individual chronotype and their association with sleep-wake patterns
(London, New York : Springer Nature, 2019, 2019)
While social zeitgebers are known to shape diurnal preference, little research has been devoted to determining the contribution of the familiar group chronotype as social zeitgeber on individual circadian rhythms and ...
Privación selectiva de sueño rem en ratas : recuperación espontánea versus enmascaramiento: un estudio de homeostasis de sueño rem
(Universidad de Chile, 2017)
La homeostasis de sueño REM refiere el proceso mediante el cual la cantidad de tiempo en este estado se mantiene dentro de límites mínimos aceptables; sin embargo existen reportes contradictorios respecto a si el sueño REM ...
Effect of simulated tidal currents on the burrow emergence rhythms of the Norway lobster (Nephrops norvegicus)
(Springer, 2015-10)
Light is the most important zeitgeber for the synchronization of biological rhythms in terrestrial organisms. In the sea, the light intensity progressively decreases, and tidal currents might control behavioural rhythms ...
Efeitos de vocalizações de co-específicos e do escuro sobre o ritmo circadiano da atividade motora em sagüis (Callithrix jacchus)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em PsicobiologiaEstudos de Comportamento; Psicologia Fisiológica, 2007-09-06)
The principal zeitgeber for most of species is the light-dark photocycle (LD), though other environment factors as food availability, temperature and social cues may act. Daily adjustment of the circadian pacemaker may ...
Modeling the Emergence of Circadian Rhythms in a Clock Neuron Network
(PUBLIC LIBRARY SCIENCESAN FRANCISCO, 2012)
Circadian rhythms in pacemaker cells persist for weeks in constant darkness, while in other types of cells the molecular oscillations that underlie circadian rhythms damp rapidly under the same conditions. Although much ...
Breastfeeding, sleep and wake circadian rhythms show distinct temporal emerging patterns
(TAYLOR & FRANCIS LTD, 2008)
The emerging patterns of breastfeeding, sleep and wake circadian rhythms in an infant and the breastfeeding emergence pattern of his elder sister are presented. Both children were raised under regular contact with photic ...
Physiology of circadian entrainment
(American Physiological Society, 2010-07)
Mammalian circadian rhythms are controlled by endogenous biological oscillators, including a master clock located in the hypothalamic suprachiasmatic nuclei (SCN). Since the period of this oscillation is of ∼24 h, to keep ...
Delay model of the circadian pacemaker
(Academic Press Ltd - Elsevier Science Ltd, 2000-06)
We present a simple and realistic model of the circadian pacemaker that can be interpreted in molecular terms. The model, which consists of a single time-delay differential equation, simulates the expression of a generic ...
The primate seahorse rhythm
(Elsevier B.V., 2015-07-10)
The main Zeitgeber, the day-night cycle, synchronizes the central oscillator which determines behaviors rhythms as sleep-wake behavior, body temperature, the regulation of hormone secretion, and the acquisition and processing ...
