Book Description
For centuries man knew about the lightning of the sky (atmospheric or physical electricity) and the numbing effects from contact with powerful electric fishes (animal electricity). Then, after proper experimentation and a synthetic ration ale, it began to appear that physical and animal electricity were related in fundamental respects. This realization was made at the end of the eighteenth century, since when the pages of history have been replete with exciting dis coveries and developments in electricity and magnetism, electrochemistry, and electrophysiology. It is hoped that this manual will enable some students to relive some of that excitement. The author remembers vividly the excitement when, as an undergraduate, he saw his first action potential. This book is not intended for any particular group of students; it should prove to be of some value to students in secondary schools, colleges, and gradu ate schools. Based on personal experience, the author feels that many teachers will also find it of use. Nor is the manual intended solely as a laboratory manual for an introductory course in neurophysiology. Some of the experiments might be introduced into the formallaboratory schedule of general or animal physiology courses. Alternatively, the various experiments might provide the bases for the beginning of special projects lasting for a full semester or even longer.

Book Description
The first evidence that electrical changes can cause muscles to contract was p- vided by Galvani (1791). Galvani’s ideas about ‘animal electricity’ were explored during the 19th and 20th century when it was firmly established that ‘electricity’ is one of the most important mechanisms used for communication by the nervous system and muscle. These researches lead to the development of ever more soph- ticated equipment that could either record the electrical changes in nerves and muscles, or elicit functional changes by electrically stimulating these structures. It was indeed the combination of these two methods that elucidated many of the basic principles about the function of the nervous system. Following these exciting findings, it was discovered that electrical stimulation and the functions elicited by it also lead to long-term changes in the properties of nerves and particularly muscles. Recent findings help us to understand the mec- nisms by which activity induced by electrical stimulation can influence mature, fully differentiated cells, in particular muscles, blood vessels and nerves. Electrically elicited activity determines the properties of muscle fibres by activating a sequence of signalling pathways that change the gene expression of the muscle. Thus, elect- cal activity graduated from a simple mechanism that is used to elicit muscle c- traction, to a system that could induce permanent changes in muscles and modify most of its characteristic properties.

Book Description
Functional electrical stimulation is the most important application in the field of clinical treatment with currents or magnetism. This technique artificially generates neural activity in order to overcome lost functions of the paralized, incontinent or sensory handicapped patient. Electricity and magnetism is also used in many cases, e.g., to stimulate bone growth or wound healing. Nevertheless, the basic mechanism of the artificial excitation of nerve and muscle fibers has become known only in the last few years. Although many textbooks are concerned with the natural excitation process there is a lack of information on the influence of an applied electrical or magnetic field. This book, written for students and biomedical engineers, should close the gap and, furthermore, it should stimulate the design of new instrumentation using optimal strategies.

Book Description
Intended for clinicians who perform electrodiagnostic procedures as an extension of their clinical examination, and for neurologists and physiatrists who are interested in neuromuscular disorders and noninvasive electrodiagnostic methods, particularly those practicing electromyography (EMG) this book provides a comprehensive review of most peripheral nerve and muscle diseases, including specific techniques and locations for performing each test.

Book Description
A pioneer of electroencephalography, Liberson (1904-94) begins his autobiography in Czarist Russia, then recounts his life and scientific work while in exile in Paris in the 1920s and 1930s and in the US after 1940. He made major contributions in neurophysiology, psycho- pharmacology, medical electrology, biological psychiatry, and rehabilitation medicine. Annotation copyrighted by Book News, Inc., Portland, OR

Book Description
In many cases of neuromuscular disorders the physician is faced with a complete lack of therapeutic approaches. This helplessness places the doctor in a position of conflict between his desire to help and his awareness that there is no treatment. In this situation it is tempting to indiscriminately use any procedure that avoids an admission of medical helplessness while satisfying the patient's demand for treatment. Electrical interventions are often used to avoid this situation. Due to the random use of therapeutic approaches it is not known what really happens. Presumptions and biased empirical observations have led to the exten sive use of different forms of electrical stimulation regimes in neuromuscular diseases. Due to this unsatisfactory situation it is necessary to know more about appropriate methods that are being used in particular disorders. The search for a better understanding of nerve-muscle interaction has shown that certain activity patterns can influence muscle. These experi mental results provide a rational basis for a possible therapeutic use of electrical stimulation of nerve and muscle. Previously most research has been conducted in normal tissue, and little is known regarding the re sponses of diseased muscle. In an interdisciplinary approach to this, it is our intention to present the current knowledge about basic principles of electrical stimulation in normal muscle. Before electrical stimulation can be accepted as a therapeutic tool, we felt it necessary to summarize the effects of activity in normal and diseased muscle and nerve.

Book Description
A study of neuroprosthetics. It is broadly divided into three sections which address: neuroanatomy and neurophysiology, biomaterials and biocompatibility, stimulation and recording techniques; clinical applications of neuroprosthetics; and future developments.

Book Description
Italian physician L Galvani demonstrated the relationship between electricity and muscle contraction that occurs in the electric fluid carried to the muscles by the nerves. He coined the term animal electricity to describe the muscle-activating force. One hundred and fifty years after he determined that muscle activation is generated by an electric fluid carried by the nerves, mathematician N. Wiener studied an artificial hand controlled by an electrical current produced in the muscles. This book discusses new developments, procedures and applications of electromyography.
