DeFelice presents this intricate subject in an easy-to-follow, stepwise fashion: he reviews the fundamentals of electricity; transfers those principles to a biological context; and expands the discussion to encompass the subject's practical dimensions. Clear definitions and intuitive descriptions characterize the presentation, which is complemented by over 150 drawings and graphs. Mathematics is kept to the minimum necessary. The text covers both excitable and non-excitable membranes and includes the plasma membrane as well as intracellular membranes. A unique, `electronics-made-simple' appendix, designed specifically for biologists, treats the operational amplifiers used in patch clamp, and other appendices offer solutions to equations and examples that illustrate principles.

Cellular biophysics is the branch of biophysics that studies cells from the perspective of a physicist or physical chemist by applying physical methods to interrogate cell structure and function, and developing models of cells using physics and physical-chemical principles. The fundamental unit of all biological life is the cell, a mass of biomolecules in watery solution surrounded by a cell membrane. One of the characteristic features of a living cell is that it controls the exchange of electrically charged ions across the cell membrane and therefore the electrical potential of its interior relative to the exterior. The organization and activities of cells are major themes in cellular biophysics, and studies have focused on observing complex structures inside cells, detecting cellular activities, and extending methods developed to study purified biological molecules to microscope-based cellular measurements. Microscopy, which functions across multiple scales of time and spatial resolution, is at the center of these studies. Most cells and tissues have electrical properties relevant to their natural function. Most cells and tissues have rather complex structure, consisting of folding and invaginating membranes and specialized connections and organelles. The localization of electrical properties is particularly important, since each of the complex structures must be expected to have a specific role in the electrical function of the tissue. Cellular Biophysics, Electrical Properties fosters progress and innovations in comprehending the nature of the biophysical mechanisms underlying the control of cellular physiological homeostasis and the consequences of its perturbation. Electrical signals are fundamental to nervous system function. The electrical properties of cells are important in determining how electrical signals spread along plasma membrane. This Advanced Topic explores the electrical characteristics of cell membranes as electrical conductors and insulators. These passive electrical properties arise from the physical properties of the membrane material and from the ion channels in the membrane. This book will serve as valuable guide for advanced graduate students and researchers dealing with the bioengineering, biophysics, physiology, and neuroscience areas, and will serve as a valued tool for biophysicists as well.

Cellular Biophysics is a quantitatively oriented basic physiology text for senior undergraduate and graduate students in bioengineering, biophysics, physiology, and neuroscience programs. It will also serve as a major reference work for biophysicists. Developed from the author's notes for a course that he has taught at MIT for many years, these books provide a clear and logical explanation of the foundations of cell biophysics, teaching transport and the electrical properties of cells from a combined biological, physical, and engineering viewpoint. Each volume contains introductory chapters that motivate the material and present it in a broad historical context. Important experimental results and methods are described. Theories are derived almost always from first principles so that students develop an understanding of not only the predictions of the theory but also its limitations. Theoretical results are compared carefully with experimental findings and new results appear throughout. There are many time-tested exercises and problems as well as extensive lists of references. The volume on the electrical properties of cells covers both electrically inexcitable cells as well as electrically excitable cells such as neurons and muscle cells. Included are chapters on lumped-parameter and distributed-parameter models of cells, linear electric properties of cells, the Hodgkin-Huxley model of the giant axon of the squid, saltatory conduction in myelinated nerve fibers, and voltage-gated ion channels.

A number of apparently unrelated phenomena in biological systems (e.g., biopolymer aggregation, cell-cell interactions, ion transport across membranes) arise from the special properties of charged surfaces. A sym posium entitled "Electrical Double Layers in Biology", which took place at the Toronto meeting of the Electrochemical Society, 12-17 May 1985, focused on the common features of these phenomena. The papers presented at that symposium are collected here and they illustrate ways in which an under standing of electrical double layers can elucidate a problem in Biology. An example of this approach can be seen from the paper I presented on ion transport and excitation, where the "unusual" ion flows during nerve excitation are actually expected if one includes the effects of electrical double layers at membrane surfaces. Furthermore, the selectivity of the ion channels in these membranes can be better understood on this basis. Other presentations account for such observations as the changes in spacing between muscle proteins during contraction, the interactions of red cells to form rouleaux, the electrical properties of algal cell membranes, electrokinetic potentials during blood flow in arteries, etc. I trust that these papers will indicate the value of electrochemistry in the study of biological systems, an area of research usually called Bioelectrochemistry, and will encourage biologists to use these ideas when approaching related problems.

Bioelectrochemistry: Principles and Practice provides a comprehensive compilation of all the physicochemical aspects of the different biochemical and physiological processes. The role of electric and magnetic fields in biological systems forms the focus of this second volume in the Bioelectrochemistry series. The most prominent use of electric fields is found in some fish. These species generate fields of different strengths and patterns serving either as weapons, or for the purpose of location and communication. Electrical phenomena involved in signal transduction are discussed by means of two examples, namely excitation-contraction coupling in muscles and light transduction in photoreceptors. Also examined is the role of electrical potential differences in energy metabolism and its control. Temporal and spatial changes of the potential difference across the membranes of nerve cells are carefully evaluated, since they are the basis of the spreading and processing of information in the nervous system. The dielectric properties of cells and their responses to electric fields, such as electrophoresis and electrorotation, are dealt with in detail. Finally, the effects of magnetic fields on living systems and of low-frequency electromagnetic fields on cell metabolism are also considered. Further volumes will be added to the series, which is intended as a set of source books for graduate and postgraduate students as well as research workers at all levels in bioelectrochemistry.
