Annotation:

The first experiment used the male Syrian hamster as the subject, as it has good wheel-running rhythms with consistent and robust activity onsets and also a well defined phase delay and advance region of the phase response curve (PRC). In this study, a double light pulse paradigm was used to examine if the clock could reset within 2 h. The second light pulse administered 2 h after an initial pulse was used to map the effects of the first light pulse on the resetting behaviour to determine whether the clock had reset to primary light pulse before receiving the second one. The results obtained i

Annotation:

Circadian clocks are biological signalling networks which have a period of ~24 hours under constant environmental conditions. They have been identified in a wide range of organisms, from cyanobacteria to mammals and through the temporal co-ordination of biological processes are believed to increase individual fitness. The mechanisms which generate these self-sustained rhythms, the pathways of entrainment and the target outputs of the clock are all areas of great interest to circadian biologists. The plant circadian clock is believed to comprise of interlocking feedback loops of transcription a

Annotation:

Drosophila melanogaster locomotor activity responds to seasonal conditions by modulating the “evening” activity component. During simulated winters of cold temperature and short days an advanced evening locomotor peak occurs with more daytime locomotor activity; on the other hand long photoperiods and warm temperatures give a delay in the evening peak, thereby avoiding a possible desiccation during the hottest times of the day. This pattern of activity is related to a thermosensitive splicing event that occurs in a 3’ intron in the period gene, with a higher level of splicing and earlier accum

Light is important for entraining circadian rhythms, which regulate a wide range of biological processes. Zebrafish have directly light responsive tissues (Whitmore et al 2000) and are thus a useful vertebrate model for circadian rhythmicity and light sensitivity. Recent studies show the pineal regulates locomotor rhythms (Li et al 2012). However, there are many unresolved questions concerning the neurobiological basis of the zebrafish clock, such as whether neuronal pacemakers, which drive rhythms in other tissues, are present throughout the brain.

Abstract Light acts as the most important regulating and entraining factor of the mammalian circadian rhythm. This rhythm has evolved to set phases, in which different physiological and behavioral events occur at the right time of the day to synchronize the organism. The mechanism of light transduction via eyes to the brain and its effects on circadian rhythmicity is well known. Yet, it has also been shown that light is able to penetrate the skull bone directly, but it is still unknown, whether transcranial light is able to affect molecules regulating circadian rhythmicity.

In order to anticipate the predictable changes in the environment associated with the earth’s rotation, most organisms possess intrinsic biological clocks. To be useful, such clocks require a reliable signal of ‘time’ from the external world. In mammals, light provides the principle source of such information; conveyed to the suprachiasmatic nucleus circadian pacemaker (SCN) either directly from the retina or indirectly via other visual structures such as the thalamic intergeniculate leaflet (IGL). Nonetheless, while the basic pathways supplying sensory information to the clock are well unders

In the last eighteen years there has been the identification of a novel photopigment, melanopsin, and its subsequent localization to human intrinsically photosensitive retinal ganglion cells (ipRGCs). Since melanopsin’s peak sensitivity is in the short wavelength portion of the visible spectrum (from 447 nm to 484 nm), there has been a steady increase in studies investigating the physiological effects of blue light.

Melatonin is rhythmically synthesized and released by the pineal gland and, in some species, retina during the night and regulates many physiological and behavioral processes in birds and mammals. Chick diencephalic astrocytes express two melatonin receptor subtypes in vitro, and melatonin plays a role in regulating metabolic activity. We examined the role of glial cells in circadian function and asked if melatonin modulated glial functions within the retina and the brain.

Early light environment has been shown to alter locomotor activity behaviour in adult rats and mice when exposed to constant light (LL), constant darkness (DD) or 12:12 hour light-dark cycles (LD). In particular, exposure to LL during lactation results in an increased ability to cope with exposure to LL as adults, implying that the ability to interpret light information is altered depending on early light environment. Therefore, the aim of this project was to explore how early light environment affects the photic response of the circadian system. The retina forms the first component of the pho

A circadian clock is an endogenous time-keeping mechanism that synchronizes several biological processes with local environment. In metazoans the circadian system is driven by a regulatory network of so called ―clock‖ genes interconnected in transcriptional-translational feedback loops that generate rhythmicity at mRNA and protein level. Sea urchin and its molecular tools can facilitate the comprehension of the evolution of the time-keeping mechanism in bilaterians. For this purpose we identified and analysed the expression of orthologous clock genes in the sea urchin larvae. Genome survey ide

This study attempts to identify the mechanism of the so-called afternoon nap zone.

Circadian clocks are biological timekeepers that help maintain an organism’s behavior and physiological state optimally timed to the Earth’s day/night cycle. To do this, these internal pacemakers must accurately keep track of time. Equally importantly, they must be able to adjust their oscillations in response to external time cues to remain properly synchronized with the environment, and correctly anticipate environmental changes. When the internal clock is offset from its surrounding day/night cycle, clinically relevant disruptions develop, ranging from inconveniences such as jet-lag to more

Annotation:

La lumière influence de nombreuses fonctions comportementales et physiologiques, comme les cycles veille-sommeil, la sécrétion de mélatonine, le réflexe pupillaire et le métabolisme du glucose. En tant que facteur environnemental clé, elle synchronise le système circadien sur un cycle de 24 heures. Les signaux lumineux sont perçus par les cellules ganglionnaires rétiniennes intrinsèquement photosensibles (ipRGCs), distinctes des bâtonnets et cônes responsables de la vision. Ces ipRGCs envoient les informations lumineuses au noyau suprachiasmatique (NSC) de l'hypothalamus, l'horloge circadienne
