Download or read book Biological Oscillators Their Mathematical Analysis written by Theodosios Pavlidis and published by Elsevier. This book was released on 2012-12-02 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological Oscillators: Their Mathematical Analysis introduces the main features of the dynamic properties of biological oscillators and the mathematical techniques necessary for their investigation. It is not a comprehensive description of all known biological oscillators, since this would require a much bigger volume as well as a different type of expertise. Instead certain classes of biological oscillators are described, and then only in as much detail as required for the study of their dynamics. The opening chapter reviews fundamental mathematical concepts and techniques which will be used in the remainder of the book. These include phase plane techniques; asymptotic techniques of Krylov, Bogoliubov, and Mitopolski; and the describing function. Subsequent chapters discuss examples of biological oscillators; phase shifts and phase response curves; the entrainment of oscillators by external inputs; the dynamics of circadian oscillators; effects of changing environment on the dynamics of biological oscillators; the features peculiar to populations of interacting oscillators; and biological phenomena attributable to populations of oscillators.
Download or read book An Introduction to Biological Rhythms written by John Palmer and published by Elsevier. This book was released on 2012-12-02 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Biological Rhythms provides an introduction to the subject of biological rhythms. The opening chapters present an overview of biological rhythms, their properties, and clock control, followed by a survey of rhythms in plants and animals. The subsequent chapters cover tidal rhythms and human rhythms; sun-compass, star-compass, and moon compass orientation of animals; the clock control of plant and animal photoperiodism; evidence for external timing of biological clocks; and models and mechanisms for endogenous timekeeping. The book also includes biographical sketches of Dr. Frank A. Brown, Jr., Morrison Professor of Biology at Northwestern University; and Dr. Leland N. Edmunds, Jr., Professor and Head of the Division of Biological Sciences at the Stony Brook campus of the State University of New York. This book is meant for the inquiring student seeking an introduction to the subject and for busy biologists in other fields who want to get a ""feel"" for the subject. It can also serve as a basic textbook for the existing biorhythms courses and act as a seed for the inauguration of new courses.
Download or read book Introducing Biological Rhythms written by Willard L. Koukkari and published by Springer Science & Business Media. This book was released on 2007-07-29 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introducing Biological Rhythms is a primer that serves to introduce individuals to the area of biological rhythms. It describes the major characteristics and discusses the implications and applications of these rhythms, while citing scientific results and references. Also, the primer includes essays that provide in-depth historic and other background information for those interested in more specific topics or concepts. It covers a basic cross-section of the field of chronobiology clearly enough so that it can be understood by a novice, or an undergraduate student, but that it would also be sufficiently technical and detailed for the scientist.
Download or read book Biological Rhythms written by Jurgen Aschoff and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in biological rhythms has been traced back more than 2,500]ears to Archilochus, the Greek poet, who in one of his fragments suggests ",,(i,,(VWO'KE o'olos pv{}J.tos txv{}pW7rOVS ~XH" (recognize what rhythm governs man) (Aschoff, 1974). Reference can also be made to the French student of medicine J. J. Virey who, in his thesis of 1814, used for the first time the expression "horloge vivante" (living clock) to describe daily rhythms and to D. C. W. Hufeland (1779) who called the 24-hour period the unit of our natural chronology. However, it was not until the 1930s that real progress was made in the analysis of biological rhythms; and Erwin Bunning was encouraged to publish the first, and still not outdated, monograph in the field in 1958. Two years later, in the middle of exciting discoveries, we took a breather at the Cold Spring Harbor Symposium on Biological Clocks. Its survey on rules considered valid at that time, and Pittendrigh's anticipating view on the temporal organization of living systems, made it a milestone on our way from a more formalistic description of biological rhythms to the understanding of their structural and physiological basis.

Download or read book Comparative Physiology and Evolution of Vision in Invertebrates written by H. Autrum and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 762 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the comparative physiology of photoreception by the Protista and the invertebrates two aspects are emphasized: (1) the diversity of visual processes in these groups and (2) their bearing upon general mechanisms of photoreception. Invertebrates have evolved a far greater variety of adaptations than vertebrates modifications aiding survival in the remarkably different biotopes they occupy. The number of species in itself suggests this multiformity; each of them has peculiarities of its own, in morphology as well as in physiology and behavior. But these special adaptations are variations on a few great themes. Although the catalogue of invertebrate species is immense, the literature concerning them nearly rivals it in extent-even if one considers only that fraction dealing with visual physiology. Taxonomy proceeds by grouping the species, categorizing them in genera, families, orders, and progressively larger units. Similarly, comparative physiology aims at an analogous, more or less compre hensive, classification. This Part A of Volume VII/6, like Part B that follows it, emphasizes the broad questions that concern groups larger than the individual species; in some cases these questions have general applicability. The middle course between approaches that are too specialized and those that are too general is often elusive, but here we attempt to follow it. The vast number of special adaptations-probably, as we have said, as large as the number of species-is beyond the range even of a handbook.
Download or read book The Timing of Sleep and Wakefulness written by J. T. Enright and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain functions like a computer composed of subsystems which in teract in a hierarchical manner. But it is not a single hierarchy, but a com plex system of hierarchies each of which has its very own and unique fea ture. One of these concerns the cyclic or rhythmic control of neuronal ac tivities which, among others, give rise to alternating states of wakefulness and sleep. The phenomenon of sleep still remains a mystery. The present monograph does not give us any new insights into its meaning and significance. Yet sleep research may not be the same after the appearance of this book be cause it gives us a comprehensive mathematical theory which opens our eyes to new insights into the mechanism of the rhythm generation that under lies the "wake-sleep" cycle. No one who has worked his way through this book can again look at ex perimental data without recognizing features which the "models" developed in its various chapters so strikingly reveal.

Download or read book Rhythmic Aspects of Behavior written by Frederick M. Brown and published by Routledge. This book was released on 2020-09-07 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1982, this book provides rich evidence of the relevance of the temporal aspects of behavior. The generalized areas of learning, memory, operant scheduled behavior, task performance, vigilance, mood and motivation and their rhythmic components are explored in varying detail. The particularized measures range from on-the-job errors, through reading efficiency to milliseconds of change in reaction time in the laboratory. The subjects range from ants to older persons. Across this range of settings, subjects, and behaviors, the message is clear: there is an interaction between time and behavior.
Download or read book The Geometry of Biological Time written by Arthur T. Winfree and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: As 1 review these pages, the last of them written in Summer 1978, some retrospec tive thoughts come to mind which put the whole business into better perspective for me and might aid the prospective reader in choosing how to approach this volume. The most conspicuous thought in my mind at present is the diversity of wholly independent explorations that came upon phase singularities, in one guise or another, during the past decade. My efforts to gather the published literature during the last phases of actually writing a whole book about them were almost equally divided between libraries of Biology, Chemistry, Engineering, Mathematics, Medicine, and Physics. A lot of what 1 call "gathering " was done somewhat in anticipation in the form of cönjecture, query, and prediction based on analogy between developments in different fields. The consequence throughout 1979 was that our long-suffering publisher re peatedly had to replace such material by citation of unexpected flurries of papers giving substantive demonstration. 1 trust that the authors of these many excellent reports, and especially of those I only found too late, will forgive the brevity of allusion I feIt compelled to observe in these substitutions. A residue of loose ends is largely collected in the index under "QUERIES. " It is c1ear to me already that the materials I began to gather several years ago represented only the first flickering of what turns out to be a substantial conflagration.
Download or read book Of Time Passion and Knowledge written by Julius Thomas Fraser and published by Princeton University Press. This book was released on 2021-03-09 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Only a wayfarer born under unruly stars would attempt to put into practice in our epoch of proliferating knowledge the Heraclitean dictum that `men who love wisdom must be inquirers into very many things indeed.'" Thus begins this remarkable interdisciplinary study of time by a master of the subject. And while developing a theory of "time as conflict," J. T. Fraser does offer "many things indeed"--an enormous range of ideas about matter, life, death, evolution, and value.
Download or read book The Physiology of Insecta written by Morris Rockstein and published by Academic Press. This book was released on 2013-10-22 with total page 591 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physiology of Insecta, Second Edition, Volume II, is part of a multivolume treatise that brings together the known facts, the controversial material, and the many still unsolved and unsettled problems of insect physiology. Since the first edition of this multivolume treatise was published, there has been a notable expansion of scientific endeavor in each of the various aspects of insect physiology. The original three-volume work has now grown to a thoroughly revised six-volume treatise. The book contains nine chapters that focus on the impact of environmental factors on the physiology of insects. The first chapter discusses the influence of temperature on insects, with attention to aspects likely to be of significance in relation to the rate at which individuals are born and die in natural populations. Separate chapters follow on the effects of humidity and radiation. Subsequent chapters deal with insect chemoreception and mechanorception; visual system, with a focus on compound eyes; sound production and the behavior associated with it; luminous insects; and the role of internal circadian oscillations in the life of insects with respect to the ""day"" outside, and on the role of the circadian system in biological time measurement.
