Electroencephalography

Why consult encyclopedic references when you only need the essentials? Practical Approach to Electroencephalography, by Mark H. Libenson, MD, equips you with just the right amount of guidance you need for obtaining optimal EEG results! It presents a thorough but readable guide to EEGs, explaining what to do, what not to do, what to look for, and how to interpret the results. It also goes beyond the technical aspects of performing EEGs by providing case studies of the neurologic disorders and conditions in which EEGs are used, making this an excellent learning tool. Abundant EEG examples throughout help you to recognize normal and abnormal EEGs in all situations. Presents enough detail and answers to questions and problems encountered by the beginner and the non-expert. Uses abundant EEG examples to help you recognize normal and abnormal EEGs in all situations. Provides expert pearls from Dr. Libenson that guide you in best practices in EEG testing. Features a user-friendly writing style from a single author that makes learning easy. Examines the performance of EEGs—along with the disorders for which they’re performed—for a resource that considers the patient and not just the technical aspects of EEGs. Includes discussions of various disease entities, like epilepsy, in which EEGs are used, as well as other special issues, to equip you to handle more cases.

This book describes the developments and improvements in electroencephalography (EEG). In recent years, digital technology has replaced analog equipments, and it is now possible to easily record and store EEG tracings and to quickly recall previously acquired material for subsequent analysis. In addition, not only static figures, but also electronic supplementary materials can be included in books, enabling EEGs to be viewed in real-time. In clinical practice, EEG still represents the most important functional examination in the study CNS development and its anatomical and physiological integrity throughout life. In the pathological context, EEG provides indispensable diagnostic information for classification of epileptic syndromes, and it is also valuable in all the other CNS diseases (infectious, cerebrovascular, neurodegenerative, etc). Furthermore, monitoring EEG can be widely used in emergency settings, such as emergency departments or intensive care units. In comatose patients, EEG provides information regarding prognosis and evaluation of the sedative effect of anesthetic drugs. Written by a group of leading national and international experts, it offers a substantial, yet practical, EEG compendium, which serves as a reference resource for physicians and neurodiagnostic technologists as well as physicians-in-training, researchers, practicing electroencephalographers and students.

The leading reference on electroencephalography since 1982, Niedermeyer's Electroencephalography is now in its thoroughly updated Sixth Edition. An international group of experts provides comprehensive coverage of the neurophysiologic and technical aspects of EEG, evoked potentials, and magnetoencephalography, as well as the clinical applications of these studies in neonates, infants, children, adults, and older adults. This edition's new lead editor, Donald Schomer, MD, has updated the technical information and added a major new chapter on artifacts. Other highlights include complete coverage of EEG in the intensive care unit and new chapters on integrating other recording devices with EEG; transcranial electrical and magnetic stimulation; EEG/TMS in evaluation of cognitive and mood disorders; and sleep in premature infants, children and adolescents, and the elderly. A companion website includes fully searchable text and image bank.

In the history of brain research, the prospect of visualizing brain processes has continually awakened great expectations. In this study, Cornelius Borck focuses on a recording technique developed by the German physiologist Hans Berger to register electric brain currents; a technique that was expected to allow the brain to write in its own language, and which would reveal the way the brain worked. Borck traces the numerous contradictory interpretations of electroencephalography, from Berger’s experiments and his publication of the first human EEG in 1929, to its international proliferation and consolidation as a clinical diagnostic method in the mid-twentieth century. Borck's thesis is that the language of the brain takes on specific contours depending on the local investigative cultures, from whose conflicting views emerged a new scientific object: the electric brain.

The standard-setting clinical electroencephalography textbook has been rewritten for the next decade of EEG technicians and resident and practicing neurologists. This Third Edition reflects the transition of the field to an all-digital environment, with fundamental changes in data recording, analysis, and interpretation. Drs. Ebersole and Pedley are outstanding educators with extensive experience in editing two of the leading journals--Journal of Clinical Neurophysiology and Epilepsia, respectively. In this volume, Ebersole and Pedley cover the full range of applications of EEG and evoked potentials in contemporary clinical practice. The book explains the most advanced instrumentation and techniques and their use in evaluating various disorders. More than 600 illustrations depict both normal and abnormal findings.

Neurological, neurovegetative, and psychic changes following surgery or in tensive care indicate alterations in cerebral function. When these changes are analyzed exactly, they are found to be by no means rare; at the same time, they present a wide spectrum of clinical manifestations. While optimal circulatory monitoring - including continuous EEG recording during anes thesia or intensive care - is today regarded as routine, the problem of objec tive and continuous monitoring of cerebral function under various forms of anesthesia, surgery, and intensive care has not been solved. Considerable improvements in clinical neurophysiology, mainly through visual and spectral analytic evaluations of the EEG, show func tional neurophysiological changes to be equivalent to, or the cause of, clinical, neurological, and psychic changes. The question of current interest, therefore, is whether anesthesiological EEG monitoring is able, both theo retically and practically, to detect and adequately interpret cerebral altera tions following perioperative measures such that these alterations can be treated or avoided accordingly. In the long run, the basic questions are to what extent can anesthesiological measures be guided by the EEG pattern and managed effectively, and can EEG analysis be significant both for the individual patient and in the general interpretation of the effect of anes thesiological procedures? Questions of the relevance and practicability of anesthesiological EEG monitoring are dealt with in this book. This study is based on an analysis of more than 1500 EEGs of patients who underwent anesthesia during surgery.

Animal Electroencephalography focuses on the use of electroencephalography (EEG) in studying brain electric activity. The manuscript first underscores the physiologic bases of EEG and the characteristics and usage of electrodes. Discussions focus on basic elements of nerve cell function, general nature of EEG, implantation of intracerebral electrodes, and affixing surface electrodes. The text then examines noise or artifact, electronic recording systems, and interpretation and analysis of EEG. Electronic principles of special relevance, electrode configurations, and electroencephalographs are discussed. The book takes a look at EEG correlates of physiologic and pathologic changes, as well as maturation of EEG, behavioral correlates, and internal influences. Experimentally produced brain diseases and naturally occurring brain diseases are also elaborated. The manuscript is a valuable reference for readers interested in electroencephalography.

The aim of this extensively illustrated work is to better the knowledge of visual analysis of EEGs for neurologists and other specialists who use electroencephalography as well as EEG technologists. This first volume covers the scope of the main features of physiological EEG wake and sleep activities in children and adults, activation procedures and the most commonly found artefacts. Indeed, a more thorough knowledge of these elements is necessary so as not to misinterpret them as pathological traits.
