Book Description
Auditory Brainstem Evoked Potentials: Clinical and Research Applications provides a solid foundation of the theoretical principles of auditory evoked potentials. This understanding is important for both the development of optimal clinical test strategies, and interpretation of test results. Developed for graduate-level audiology students, this comprehensive text aims to build a fundamental understanding of auditory evoked brainstem responses (ABR), and their relationship to normal and impaired auditory function, as well as its various audiologic and neurootologic applications. In addition to covering the classical onset ABR, the book provides a thorough review of sustained brainstem responses elicited by complex sounds, including auditory steady state response (ASSR), envelope following response (EFR), and frequency following response (FFR), and the growing clinical and research applications of these responses. By exploring why certain stimulus manipulations are required to answer specific clinical questions, the author provides the resources needed for students and clinicians to make reasoned decisions about the optimal protocol to use in a given situation. Key Features: * A full chapter devoted to laboratory exercises * Numerous illustrations to help explain key concepts * Description of neural bases underlying amplitude and latency changes * Troubleshooting techniques * End-of-chapter summaries

Book Description
Evoked potentials are potentials that are derived from the peripheral or central nervous system. They are time locked with an external stimulus and can be influenced by subjective intentions. Evoked potentials have become increasingly popular for clinical diagnosis over the last few years. Evoked potentials from the visual system are used by ophthalmologists in order to localize the abnormalities in the visual pathway. The otologists are mainly involved in brainstem auditory evoked potentials, while the pediatricians, neonatologists, neurologists and clinical neurophysiologists make use of multimodal stimulation. The psychiatrists and psychologists, generally, examine the slow potentials such as P300 and CNV. Anesthesiologists use short latency somatosensory and visual evoked potentials in order to monitor the effectiveness of the anesthesia. Pharmaco evoked potentials are very promising measures for the quan tification of the effectiveness of drug action on the cerebral cortex. Urologists are more and more involved in pudendal somatosensory evoked potentials and in the intensive care unit evoked potentials are used in order to monitor the functional state of the central nervous system of the patient. This overwhelming number of examinations and exam ina tors clearly demonstrates the need for guidelines and standardization of the methods used. The evoked potential metholody is restricted by the relative poor signal to noise ratio. In many diseases this signal to noise ratio decrease rapidly during the progression of the illness. Optimal technical equipment and methodology are therefore essential.

Book Description
Evoked potentials have been used for decades to assess neurologic function in outpatient studies and are now routinely used in the operating room during surgery. Illustrated Manual of Clinical Evoked Potentials is a modern, practical guide to performing these studies and interpreting the results. The book is uniquely organized as a singular resource that provides the necessary background for understanding and conducting evoked potential studies. It functions as a multi-purpose text, atlas, and reading session, with numerous examples of studies and findings and discussion of key takeaways. Divided into five chapters, the book opens with an introduction to the basics of data acquisition and interpretation that lays the foundation for the modality-specific chapters that follow. The next group of chapters are in-depth reviews of visual, brainstem auditory, and somatosensory evoked potentials. Each of these chapters lays out the specifics of the modality and study protocol with examples to show how things should—and should not—be done. Sample studies with discussions about how to interpret them highlight a particular aspect of normalcy or pathology. Imaging correlates are provided to emphasize salient points and offer perspective. The final chapter is an overview of the use of evoked potentials during surgery with imaging and case discussions to introduce the reader to this very important application. Key Features Detailed review of methodology of evoked potential studies Many examples of actual patient studies with imaging correlates Interpretation of each evoked potential study presented in detail “Reading session”-like discussion of each example Special chapter on evoked potentials in the operating room

Book Description
Intraoperative neurophysiologic monitoring has shown a steady increase in use for surgeries in which neural structures may be at risk of injury. Some of the surgical techniques used carry inherent risks, and these risks have changed the way in which neurophysiologic monitoring has impacted patient safety and quality of care during surgical procedures. It is therefore crucial that those performing and interpreting intraoperative neurophysiologic monitoring are adequately trained. This book is a comprehensive guide to the current practice of intraoperative neurophysiology with chapters on various modalities and clinical uses. Separate chapters devoted to anesthesia, operating room environment, special considerations in pediatrics and the interpretation and reporting of neurophysiologic data are useful and complementary. Questions and detailed answers on the topics covered can be found on the accompanying website for study review. This book will be useful to the trainee as well as the neurophysiologist already in practice.
