Book Description
Electrons are involved in all electrical phenomena, and living cells cannot be an exception. This book takes on a decidedly different approach to existing texts on electrophysiology, by considering electrical physiological processes from the viewpoint of electron flow, rather than the conventional notion of ion movement. It concisely describes the theoretical background of electron density and cellular voltage, before exploring thought-provoking questions such as the relationship between electrolyte distribution and transmembrane potential, and the source of electricity generation in living cells. A new electromagnetic theory of muscular function is presented, and all topics of relevance — including the electrophysiology of invertebrates, plants, fungi and bacteria — are comprehensively covered. Using plain language and more than 40 original illustrations, the author has designed each chapter to provide a succinct overview of an individual topic in a format that appeals to both the expert and the uninitiated. Electromagnetism, Quanta, and Electron Flow in the Electrophysiology of Living Cells proffers a refreshingly new way to understand a fascinatingly old subject.

Conversations on Cardiac Physiology
Author: Mark Noble
Publisher: Cambridge Scholars Publishing
ISBN: 1527556417
Category : Medical
Languages : en
Pages : 175
Book Description
This book addresses and corrects widespread misconceptions regarding heart physiology. Such misconceptions include: the voltage in cells is attributed to potassium ion concentration differences between the extracellular and intracellular compartments, which are the same in all organs of the body, whereas the voltage in cells of these same organs vary widely. This book argues that depolarisation and repolarisation can be explained by electron outflow and mitochondrial production, respectively; and that the trigger for internal calcium ion release is calcium ions bound to the inner leaflet of the cell membrane. In the book, Starling’s Law is contrasted with contractility increase, and it is posited that hypertension is not caused by salty diet, coronary artery disease risk is not correlated with total cholesterol (rather, only with some specific cholesterols), and that drug administration should be titrated.

Book Description
Introduction to Electrophysiological Methods and Instrumentation, Second Edition covers all topics of interest to electrophysiologists, neuroscientists and neurophysiologists, from the reliable penetration of cells and the behavior and function of the equipment, to the mathematical tools available for analyzing data. It discusses the pros and cons of techniques and methods used in electrophysiology and how to avoid pitfalls.

Starling’s Law of The Heart Revisited
Author: Henk Keurs
Publisher: Springer Science & Business Media
ISBN: 9400913133
Category : Medical
Languages : en
Pages : 157
Book Description
H. E. D. J. TER KEURS & M. I. M. NOBLE The "Starling's Law of the Heart" and "The Frank-Starling Mechanism" have long been the cornerstone of cardiac mechanical physiology. It is often forgotten that Frank and Starling carried out fundamentally different exper iments. Frankl measured the isovolumic pressure developed by frog heart at different volumes. He therefore discovered the pressure-volume-volume rela tionship which depends directly on the force-length relationship of the 2 sarcomeres. Starling ,3 studied cardiac shortening as manifest by cardiac output and its relationship to end-diastolic conditions as manifest by right atrial pressure. Thus he was studying the ability of cardiac muscle to shorten more at a given load from a greater initial length. Starling in the promulga 4 tions of his law implied a common mechanism for these two phenomena and spoke of the "energy liberated" being a function of initial muscle fiber length. However, there has been much confusion about the interrelationship between the two different aspects studied by Frank and Starling. The 1960s saw the era of isolated cardiac muscle mechanics, beginning with 5 the paper of Abbott and Mommaerts. Whole muscle length-tension relations were equated with sarcomere-length-tension relations by fixation of muscle at a particular point on the curve and determination of sarcomere length by electronmicroscopy.

QED Coherence in Matter
Author: Giuliano Preparata
Publisher: World Scientific
ISBN: 9789810222499
Category : Science
Languages : en
Pages : 264
Book Description
Up until now the dominant view of condensed matter physics has been that of an ?electrostatic MECCANO? (erector set, for Americans). This book is the first systematic attempt to consider the full quantum-electrodynamical interaction (QED), thus greatly enriching the possible dynamical mechanisms that operate in the construction of the wonderful variety of condensed matter systems, including life itself.A new paradigm is emerging, replacing the ?electrostatic MECCANO? with an ?electrodynamic NETWORK,? which builds condensed matter through the long range (as opposed to the ?short range? nature of the usual electrostatic forces) electrodynamical interaction; this interaction creates ?coherent configurations? of the elementary systems (atoms and molecules), which oscillate in phase with a coherent macroscopic (and classical) electromagnetic field that, through the strong interaction with matter, remains trapped inside it.

Biophysics
Author: William Bialek
Publisher: Princeton University Press
ISBN: 1400845572
Category : Science
Languages : en
Pages : 653
Book Description
A physicist's guide to the phenomena of life Interactions between the fields of physics and biology reach back over a century, and some of the most significant developments in biology—from the discovery of DNA's structure to imaging of the human brain—have involved collaboration across this disciplinary boundary. For a new generation of physicists, the phenomena of life pose exciting challenges to physics itself, and biophysics has emerged as an important subfield of this discipline. Here, William Bialek provides the first graduate-level introduction to biophysics aimed at physics students. Bialek begins by exploring how photon counting in vision offers important lessons about the opportunities for quantitative, physics-style experiments on diverse biological phenomena. He draws from these lessons three general physical principles—the importance of noise, the need to understand the extraordinary performance of living systems without appealing to finely tuned parameters, and the critical role of the representation and flow of information in the business of life. Bialek then applies these principles to a broad range of phenomena, including the control of gene expression, perception and memory, protein folding, the mechanics of the inner ear, the dynamics of biochemical reactions, and pattern formation in developing embryos. Featuring numerous problems and exercises throughout, Biophysics emphasizes the unifying power of abstract physical principles to motivate new and novel experiments on biological systems. Covers a range of biological phenomena from the physicist's perspective Features 200 problems Draws on statistical mechanics, quantum mechanics, and related mathematical concepts Includes an annotated bibliography and detailed appendixes

Matter and Mind
Author: Mario Bunge
Publisher: Springer Science & Business Media
ISBN: 9048192250
Category : Science
Languages : en
Pages : 325
Book Description
This book discusses two of the oldest and hardest problems in both science and philosophy: What is matter?, and What is mind? A reason for tackling both problems in a single book is that two of the most influential views in modern philosophy are that the universe is mental (idealism), and that the everything real is material (materialism). Most of the thinkers who espouse a materialist view of mind have obsolete ideas about matter, whereas those who claim that science supports idealism have not explained how the universe could have existed before humans emerged. Besides, both groups tend to ignore the other levels of existence—chemical, biological, social, and technological. If such levels and the concomitant emergence processes are ignored, the physicalism/spiritualism dilemma remains unsolved, whereas if they are included, the alleged mysteries are shown to be problems that science is treating successfully.
