Mammalian Diurnality: Some Facts and Gaps
- 2003
Biology
Some recent data on circadian mechanisms in diurnal mammals is reviewed and general themes that appear to be emerging from this work are considered, in terms of the implications they have for the evolution and neural substrates of a day-active way of life.
Mechanisms of Circadian Systems in Animals and Their Clinical Relevance
- 2015
Medicine, Biology
A general perspective of circadian rhythmicity and its mechanisms will be presented; a brief summary of the basic concepts and its biological relevance are presented; an account of the main ideas which lead to the characterization of circadian clocks among different species and levels of organization are provided.
Entrainment memories: What does stable mean?
- 2018
Biology
It is hypothesized that the long-range, multi-cycle component in entraining requires a third parameter of description additional to current internal phase and zeitgeber condition, which originates from the differential of the two or more consecutive periodic situations.

Biological Timekeeping: Scientific Background
- 2020

It is critical to further the understanding of the mechanisms underlying the circadian system to develop new therapies and strategies for maintenance of the circadian clock in the authors' 24/7 world.
TRP channels: a missing bond in the entrainment mechanism of peripheral clocks throughout evolution
- 2015
Biology
The present review brings some evidence of how these programs may have co-evolved in systems able to deal with 2 or more environmental clues, and how they similarly function in different group of animals, stressing how important temperature and light were to establish the temporal organizations.
Entrainment Concepts Revisited
- 2010
Biology, Physics
A new approach to predict and model entrainment of circadian clocks by light is suggested, based on a circadian integrated response characteristic (CIRC) that describes how the circadian system integrates light signals at different circadian phases, without specifying exactly when and how fast its progression is affected.

Circadian Systems: Entrainment
- 1981
Biology
The circadian rhythmicity of eukaroytic organisms is dictated by an innate program that specifies the time course through the day of many aspects of metabolism and behavior, and this program is subject to entrainment by one or more of the external cycles whose period it closely approximates.
TONIC AND PHASIC EFFECTS OF LIGHT IN THE ENTRAINMENT OF CIRCADIAN RHYTHMS
- 1977
Biology, Environmental Science
The mechanism of entrainment of circadian rhythms by the natural cycle of light and darkness has received considerable interest, and one of the main obstacles has been ignorance about both the photoreceptors involved and the sensory pathways to the circadian pacemakers.
Characteristics and Variability in Entrainment of Circadian Rhythms to Light in Diurnal Rodents
- 1982
Biology
In a comparative analysis of functional aspects of circadian pacemakers in four species of nocturnal rodents, Pittendrigh and Daan have shown that various pacemaker properties, such as the stability of the period, the shape of the phase response curve (PRC), the light-dependence of τ, and the ranges of entrainment to light cycles, vary interdependently.
Accuracy of Circadian Entrainment under Fluctuating Light Conditions: Contributions of Phase and Period Responses
- 1999
Biology, Environmental Science
The results suggest that during entrainment, the pacemaker adjusts its period to 24 h, after which daily phase shifts to compensate for differences between the periods of the zeitgeber and the clock are no longer necessary.
Aftereffects of Entrainment on the Period of the Pacemaker in the Eye of the Mollusk Bulla gouldiana
- 1997
Biology
The results show that isolated eyes can express aftereffects and indicate that coupling between ocular pacemakers and efferent signals from the cerebral ganglion diminish the effects of entrainment on the free-running period of the rhythm from the eye.
THE ECOTOPIC SPECIALIZATION OF ANOPHELES HOMUNCULUS; AND ITS RELATION TO COMPETITION WITH A. BELLATOR
- 1950
Environmental Science, Biology
The results demonstrated that the species do diverge in microclimatic requirement in such a way that they exhibit markedly dissimilar distributions in the diverse humidity conditions that occur in the area where they are sympatric.
Phase Control of Ultradian Feeding Rhythms in the Common Vole ( Microtus arvalis): The Roles of Light and the Circadian System
- 1993
Biology, Environmental Science
This study addresses the question of how resetting of the ultradian rhythm, a prerequisite for synchronization, is achieved in common voles without circadian rhythmicity.
Photoperiodic control of circadian activity rhythms in diurnal rodents
- 1980
Biology, Environmental Science
The data suggest that the parametric and non-parametric contributions to entrainment are different in these two rodent species.
Can the circadian system of a diurnal and a nocturnal rodent entrain to ultraviolet light?
- 2000
Biology, Environmental Science
It is argued that the role of ultraviolet light as a natural Zeitgeber is probably limited, and possible functions of ultraviolet lens filters in diurnal mammals are discussed, and compared with nocturnal mammals and diurnal birds.
Natural Entrainment without Dawn and Dusk: The Case of the European Ground Squirrel (Spermophilus citellus)
- 1999
Environmental Science, Biology
Observational data collected in the field and in enclosures show that diurnal, burrow-dwelling European ground squirrels never were above ground during twilight at dawn or at dusk, and the animals do not perceive the rapid natural light-dark transitions that occur at civil twilight.
