Book Description
This book addresses the molecular bases of some of the most important biochemical rhythms known at the cellular level. Clarifying the mechanism of these oscillatory phenomena is of key importance for understanding the origin as well as the physiological function of these rhythms, and the conditions in which simple periodic behaviour transforms into complex oscillations, including bursting and chaos. The approach rests on the analysis of theoretical models closely related to experimental observations. Among the main rhythms considered are glycolytic oscillations observed in yeast and muscle, oscillations of cyclic AMP in Dictyostelium amoebae, intracellular calcium oscillations observed in a variety of cell types, the mitotic oscillator that drives the cell division cycle in eukaryotes, and circadian oscillations of the period protein (PER) in Drosophila. For each of these phenomena, experimental facts are reviewed and mathematical models presented.

Book Description
Recent years have seen spectacular advances in the field of circadian biology. These have attracted the interest of researchers in many fields, including endocrinology, neurosciences, cancer, and behavior. By integrating a circadian view within the fields of endocrinology and metabolism, researchers will be able to reveal many, yet-unsuspected aspects of how organisms cope with changes in the environment and subsequent control of homeostasis. This field is opening new avenues in our understanding of metabolism and endocrinology. A panel of the most distinguished investigators in the field gathered together to discuss the present state and the future of the field. The editors trust that this volume will be of use to those colleagues who will be picking up the challenge to unravel how the circadian clock can be targeted for the future development of specific pharmacological strategies toward a number of pathologies.

Book Description
With the invitation to edit this volume, I wanted to take the opportunity to assemble reviews on different aspects of circadian clocks and rhythms. Although most c- tributions in this volume focus on mammalian circadian clocks, the historical int- duction and comparative clocks section illustrate the importance of various other organisms in deciphering the mechanisms and principles of circadian biology. Circadian rhythms have been studied for centuries, but only recently, a mole- lar understanding of this process has emerged. This has taken research on circadian clocks from mystic phenomenology to a mechanistic level; chains of molecular events can describe phenomena with remarkable accuracy. Nevertheless, current models of the functioning of circadian clocks are still rudimentary. This is not due to the faultiness of discovered mechanisms, but due to the lack of undiscovered processes involved in contributing to circadian rhythmicity. We know for example, that the general circadian mechanism is not regulated equally in all tissues of m- mals. Hence, a lot still needs to be discovered to get a full understanding of cir- dian rhythms at the systems level. In this respect, technology has advanced at high speed in the last years and provided us with data illustrating the sheer complexity of regulation of physiological processes in organisms. To handle this information, computer aided integration of the results is of utmost importance in order to d- cover novel concepts that ultimately need to be tested experimentally.

Book Description
Chronobiology is the study of adaptations evolved at all levels of organization by living organisms to cope with regular geophysical cycles in the environment. The Earth s rotation originates alternation of light and darkness with a 24-h period; this signal allowed primordial organisms to keep track of time, adjust their internal temporal order, and anticipate external time. This capability fostered the development in living matter of endogenous temporal organization of cellular process over an approximately 24-h period. The cellular machinery that generates this ability is known as the biological clock, and its outputs as circadian rhythms. Such clocks can be found in nearly all organisms, from simple bacteria to insects, mammals, and of course, humans. The selective advantage conferred to all organisms by the biological clock comprises coordination of molecular, physiological, and behavioral processes, so as to ensure its occurrence during the daily cycle s optimal time. When organisms are maintained in an environment with strong time signals (zeitgebers) such as the light-dark cycle, each of their circadian rhythms establishes a stable relationship with each other and with the external cycle, and becomes an entrained system. Different species and different individuals within each species are coupled with their own typical phases to the natural 24-h cycle. Thus, time is embedded in our genes, and circadian clocks have emerged several times during evolution as a result of convergence to meet a common need. And although key proteins are not conserved, all clocks known to date in eukaryotes involve transcriptional-translational feedback loops. Over the last decades, chronobiology has expanded enormously, is emerging independently in many fields, and it is one of the most interdisciplinary fields in biology. While it has not been easy to understand how a biological clock works in an organism, research with different models from single-cell organisms to complex multicellular plants and animals have provided us insight concerning the ticking of the clock. Identification of circadian rhythms in biochemical and behavioral parameters in different unicellular organisms, localization of different oscillators in combination with behavioral outputs markers by neurobiological techniques in insects and mammals, as well as molecular genetics that has led to identification and cloning of clock genes in several species including humans have rendered chronobiology a diverse and dynamic discipline, with not only biological relevance but also important social and medical implications. Our goal in editing this book was to provide a comparative view of our current knowledge regarding circadian rhythms and clocks at different phylogenetic levels. The authors contributing to this volume review both circadian molecules and mechanisms in representative groups ranging from simple organisms as unicells to complex ones such as invertebrates and non-mammal and mammal vertebrates. The book reflects and is a token of different approaches to the field, such as regulation molecules and their biochemical pathways involved in either circadian or exogenous aspects of the rhythmic process and its regulation in photoautotrophic unicells and the neurobiological and molecular bases of circadian oscillators in some invertebrates and vertebrates. A number of works are focused in the importance of environmental, social, and nutrient temporal signals as synchronizing agents in insects and in different vertebrate models. These reviews are not only centered on the adult organism at the integrative level, but also provide an ontogenetic view at behavioral, physiological, and molecular levels. Furthermore, they supply evidence on several organs as potential sources of circadian signaling for different vertebrate groups, which indicates multioscillatory circadian systems similar to those proposed for some invertebrates. In Chapter 1, Rüdiger Hardeland revises the importance of tryptophan metabolic pathways in two unicells, Euglena gracilis, and the dinoflagellate, Lingulodinium polyedrum. Barbara-Ann Battelle, in Chapter 2, reviews and describes current knowledge of the circadian system of a Chelicerata, Limulus polyphemus, visual inputs into the central clock, and efferent pathways of the clock to the eyes, in addition to the molecular mechanisms underlying these processes. In Chapter 3, María Elena Durán-Lizárraga et al. review the role of different crustacean neuropeptides in the regulation of several physiological processes, such as those proposed as controlled by the circadian system of decapoda, particularly in crayfish. Claudio R. Lazzari and Teresita C. Insausti examine, in Chapter 4, the importance of circadian rhythms from insect s populations, closely associated with the history of chronobiology and the Pittendrigh pioneering work. Continuing on insects, the concept of the superorganism and the interaction of rhythms at different frequencies in different cohorts of individuals forming a colony is presented in Chapter 5 by Mirian David-Marques and Cintia Etsuko-Yamashita. In dealing with vertebrates, Raquel Carvalho and Luiz Menna-Barreto in Chapter 6 address fish from the phenomenology of circadian rhythms to the description of the underlying multioscillatory system, finally reviewing its ecological and evolutionary relevance of these species as a model. The following chapter (7) by Carolina Escobar et al. offers an integrative view of the so-called food-entrained oscillator in rodents. Then, in Chapter 8 Ivette Caldelas and colleagues provide us with an ontogenetic approach to non-visual entrainment of the circadian system, an alternative view of the food-entrained oscillator, using as a natural model the newborn rabbit. Still in the area of restricted food availability as an entraining signal, in Chapter 9 Adrián Báez-Ruíz et al. provide yet another perspective of this phenomenon, which stresses the role of liver physiology and biochemistry in the regulation of food ingestion and hepatic circadian rhythmicity. Finally, in Chapter 10 Raúl Aguilar-Roblero and colleagues review the role of the rodent suprachiasmatic nuclei as a biological clock for the mammalian circadian system, with emphasis on molecular and cellular aspects involved in the first steps of coding biological time into a signal readable by its neuronal targets. We have attempted to provide a panoramic perspective of the multiple approaches for addressing the study of the circadian system in different organisms. Selection of contributions included certain aspects of circadian rhythms not easily found in other reviews. We are indebted to the enthusiastic response of the entire group of contributors, all distinguished professors from universities from different countries, in achieving publication of this volume. We hope readers will find the text useful and that it will perhaps further promote their interest in this area of biology.

Book Description
Studies of mechanisms in the brain that allow complicated things to happen in a coordinated fashion have produced some of the most spectacular discoveries in neuroscience. This book provides eloquent support for the idea that spontaneous neuron activity, far from being mere noise, is actually the source of our cognitive abilities. It takes a fresh look at the coevolution of structure and function in the mammalian brain, illustrating how self-emerged oscillatory timing is the brain's fundamental organizer of neuronal information. The small-world-like connectivity of the cerebral cortex allows for global computation on multiple spatial and temporal scales. The perpetual interactions among the multiple network oscillators keep cortical systems in a highly sensitive "metastable" state and provide energy-efficient synchronizing mechanisms via weak links. In a sequence of "cycles," György Buzsáki guides the reader from the physics of oscillations through neuronal assembly organization to complex cognitive processing and memory storage. His clear, fluid writing-accessible to any reader with some scientific knowledge-is supplemented by extensive footnotes and references that make it just as gratifying and instructive a read for the specialist. The coherent view of a single author who has been at the forefront of research in this exciting field, this volume is essential reading for anyone interested in our rapidly evolving understanding of the brain.
