Book Description
This volume is a collection of papers designed to increase awareness and utilization of fluctuation theory for the description of ionic events at the membrane. The papers are revised and updated versions of presentations made at a workshop entitled "Noise Measurements as a Probe of Ionic Conductance. " As a result of discussions held at that meeting, the participants were asked to provide selected chapters designed to provide detailed descriptions of the theory and its application to a number of membrane channels. Fluctuation theory was developed initially to explain statistical fluctuations of ordinary physical quantities such as random collisions between gas molecules and walls. As knowledge of ionic pores has advanced, it has become apparent that randomized fluctuations could be utilized to characterize pore behavior in excitable and epithelial membranes. Because of the increased awareness of the applicability of fluctuation theory, the workshop participants were invited to contribute papers to this volume to provide them with an opportunity to teach others the essentials of noise measurements. The emphasis of this volume is on the practical steps which must be followed to make and interpret measurements of noise, both noise produced by natural fluctuatjons of the transport system, and noise which is the response to an applied stochastic signal. This collection of papers is meant to emphasize practical limitations as well as practical and theoretical advantages of such measurements.

Book Description
I started working on membrane noise in 1967 with David Firth in the Department of Physiology at McGill University. I began writing this book in the summer of 1975 at Emory University under a grant from the National Library of Medicine. Part of the writing was also done at the Marine Biological Laboratory Library in Woods Hole and in the Library of the Stazione Zoologica in Naples. I wrote this book because in the intervening years membrane noise became a definable subdivision of membrane biophysics and seemed to deserve a uniform treatment in one volume. Not surprisingly, this turned out to be much more difficult than I had imagined and some areas of the subject that ought to be included have been left out, either for reasons of space or because of my own inability to keep up with all aspects of the field. This book is written for biologists interested in noise and for physicists and electrical engineers interested in biology. The first three chapters attempt to bring both groups to a common point of understanding of electronics and electrophysiology necessary to the study of noise and impedance in membranes. These chapters arose out of a course given over a period of six years to electrical engineers from the Georgia Institute of Technology and biologists from Emory University School of Medicine.

Book Description
Thermodynamics of Membrane Receptors and Channels synthesizes a wealth of new information regarding the biophysics of membrane proteins. New insights provided by molecular genetics, single channel recording, and high resolution structural techniques are discussed from a conceptual perspective. Basic theoretical topics are introduced, developed, and then extensively illustrated with recent results from the literature or data from the authors' own laboratories. Theoretical and experimental information is incorporated into in-depth discussions of ion permeation mechanisms, ion channel and receptor conformational changes, aggregate activity of complexes of lipids and proteins, and how coupling is achieved between different energy modes in the many transduction systems residing in biomembranes. Thermodynamics of Membrane Receptors and Channels will be valuable both as a learning aid and a reference for biophysicists, neuroscientists, cell biologists, physiologists, and other researchers investigating any aspects of biomembranes.

Book Description
The main purpose of this book is to unify approaches and ideas in the field of aneural sensory transduction. This field has recently come to the attention of several research groups in various disciplines, and their number seems to be growing. Unfortunately, because of the diverse scientific backgrounds of the researchers in the field, the apparent heterogeneity of experimental techniques (i. e. , behavioral response analysis, sophisticated biochemical and genetic manipulations, conventional and pulsed laser spectroscopy) and theoretical approaches may be discouraging, for both the experienced worker and the new comer. Actually, this heterogeneity is more apparent than real, and unifying concepts, approaches, and ideas already exist, particularly with respect to all the questions concerning the role of membranes and their properties (such as ion permeability, electric potentials, and active transport) in the various steps of sensory perception and transduction processes. It is currently accepted that most, if not all, the fundamental facts in molecular sensory physiology of aneural organisms, be they chemosensory, photosensory, or geosensory, can ultimately be understood in terms of a few basic ideas. Each chapter of this book emphasizes and clarifies the role of mem brane properties and phenomena in the particular sensory response examined. Of course, in some cases, this task has been rather complex because of the limited amount of experimental data clearly supporting a membrane-based model of sensory transduction.

Book Description
The second edition of Physiology of Membrane Disorders represents an extensive revision and a considerable expansion of the first edition . Yet the purpose ofthe second edition is identical to that of its predecessor, namely, to provide a rational analysis of membrane transport processes in individual membranes, cells, tissues, and organs, which in tum serves as a frame of reference for rationalizing disorders in which derangements of membrane transport processes playa cardinal role in the clinical expression of disease. As in the first edition, this book is divided into a number of individual, but closely related, sections. Part V represents a new section where the problem of transport across epithelia is treated in some detail. Finally, Part VI, which analyzes clinical derangements, has been enlarged appreciably. THE EDITORS xi Preface to the First Edition The purpose of this book is to provide the reader with a rational frame of reference for assessing the pa thophysiology of those disorders in which derangements of membrane transport processes are a major factor responsible for the clinical manifestations of disease. In the present context, we use the term "membrane transport to refer to those molecular processes whose cardinal function, broadly speaking, is processes" in a catholic sense, the vectorial transfer of molecules-either individually or as ensembles-across biological interfaces, the latter including those interfaces which separate different intracellular compartments, the cellular and extracellular com partments, and secreted fluids-such as glomerular filtrate-and extracellular fluids.

Book Description
Voltage-sensitive ion channels are macromolecules embedded in the membranes of nerve and muscle fibers of animals. Despite decades of intensive research under the traditional approach of gated structural pores, the relation between the structure of these molecules and their function remains enigmatic. This book examines physically oriented approaches not covered in other ion-channel books, and it develops a new physics-based approach to the problem of molecular excitability.
