Basic Concepts of Clinical Electrophysiology in Audiology


Book Description

Basic Concepts of Clinical Electrophysiology in Audiology is a revolutionary textbook, combining the research and expertise of both distinguished experts and up-and-coming voices in the field. By taking a multidisciplinary approach to the subject, the editors of this graduate-level text break down all aspects of electrophysiology to make it accessible to audiology students. In addition to defining the basics of the tools of the trade and their routine uses, the authors also provide ample presentations of new approaches currently undergoing continuing research and development. The goal of this textbook is to give developing audiologists a broad and solid basis of understanding of the methods in common or promising practice. Throughout the text, individual chapters are divided into “episodes,” each examining a facet of the overarching chapter’s topic. With different experts handling each episode, readers are exposed to outstanding professionals in the field. This text singularly stitches together the chapters and their episodes to build from foundational concepts to more complex issues that clinicians are likely to face on their road to full clinical competency. As collections of episodes, the writers and editors thus endeavor to present a series of stories that build throughout the book, in turn allowing readers to build a broader interest in the subject. Key Features * Heads Up sections in each chapter introduce more advanced content to expose readers to what lies beyond the basic level and further enhance the main chapter content and “entertainment value” * Take home messages at the end of each chapter serve to focus the reader’s attention, encourage review, and discourage superficial learning by “just reading the abstract” * More than 450 innovative illustrations use combinations of panels, insets, and/or gray tone to facilitate reader understanding, optimize portrayal of data, and unify concepts across chapters * Numerous case studies and references to practical clinical issues and results are included throughout the book * Keywords are highlighted in-text to improve both attention and retention of critical terms and ease of returning to review them




The Electrophysiology and Layout of the Auditory Nervous System


Book Description

This volume contains a brief account of the principles underlying the organization and functions of the auditory nervous system, and is a continuation of a previous study, The Anatomy and Physiology of the Peripheral Hearing Mechanism, which takes the reader up to, but does not include, the first-order neuron. These volumes, with the addition of a third, Psychoacoustics, are designed as texts for a one-semester course on the ear and hearing. A recommended preliminary for the student using these texts is a semester of experimental or, preferably, physiological psychology, or a minimum of one semester of introductory speech pathology/audiology, including the elementary principles of neurophysiology. The student may find a few titles helpful in this respect listed in the Suggested Readings at the back of this volume.




Human Auditory Evoked Potentials


Book Description

This book reviews how we can record the human brain's response to sounds, and how we can use these recordings to assess hearing. These recordings are used in many different clinical situations--the identification of hearing impairment in newborn infants, the detection of tumors on the auditory nerve, the diagnosis of multiple sclerosis. As well they are used to investigate how the brain is able to hear--how we can attend to particular conversations at a cocktail party and ignore others, how we learn to understand the language we are exposed to, why we have difficulty hearing when we grow old. This book is written by a single author with wide experience in all aspects of these recordings. The content is complete in terms of the essentials. The style is clear; equations are absent and figures are multiple. The intent of the book is to make learning enjoyable and meaningful. Allusions are made to fields beyond the ear, and the clinical importance of the phenomena is always considered.




Auditory Evoked Potentials


Book Description

Written by experts with extensive clinical and scientific experience, this comprehensive textbook presents the state of the art in auditory evoked potentials. Opening chapters explain the nature of electrical fields that generate surface recorded potentials, summarize the imaging modalities that complement evoked potential studies, and review acoustics and instrumentation. Major sections examine the anatomy and physiology of the auditory periphery, brainstem, and cortex and the principles and clinical applications of auditory, myogenic, visual, somatosensory, and vestibular evoked potentials. Chapters present hands-on laboratory exercises and clinical case studies. A full-color insert includes 3D images from multi-channel evoked potentials and functional imaging.







Auditory System


Book Description

after heated and often bitter debates, SIEBENMANN'S opinion finally prevailed, i. e. , a contribution to cochlear lesions due to vibrations of the floor transmitted via bone conduction could not be demonstrated. For one thing, it was hard to see how appreciable amounts of energy could reach the ears in this manner, considering the attenuation that is bound to occur across each of the many joints along the pathway involved. In some older audiological surveys conducted in industry (e. g. , TEMKIN, 1933), groups of workmen were found who displayed signs of apical-turn lesions, i. e. , low-tone hearing losses for air and for bone. Such lesions could not be expected to results from exposure to air-borne sounds because of the low-frequency attenu ation of the middle ear. Although WITTMAACK'S explanation, which was frequently invoked in such reports, does no longer appear tenable, such apical-turn lesions could conceivably be caused by bone conduction components of high-intensity noise in the sense of BEKESY (1948). - As far as I am aware of, no newer studies have been conducted in this problem area, and the older experiments and/or surveys were done at times before signal parameters could be precisely controlled or measured. A detailed, critical review of the older studies on the potential contribution of bone-conducted energy to industrial hearing loss and its underlying pathology may be found in Werner (1940) who, incidently, favored SIEBENMANN'S point of VIew.




Assessment and Management of Central Auditory Processing Disorders in the Educational Setting


Book Description

This book takes a comprehensive look at the basic principles underlying central auditory processing disorders (CAPD) and the screening, assessment, and management of these disorders in school-age children. It focuses on the practical application of scientific theory in an easy to read, clinically applicable format. It also includes step-by-step assessment tips, normative data, methods of test interpretation, development and implementation of management plans, and integration of central auditory information. Learning and communication profiles are also included to provide a comprehensive picture of CAPD assessment and management.




Auditory Information Processing


Book Description

This book explains neural function at the level of ion channels and membrane excitability in neurons along the ascending auditory pathway. Airborne sound information is captured by the ears, transformed to neural electrical signals, and then processed in the brain. Readers will find full descriptions of these processes of signal transduction and transformation. First, it is described how, at the level of hair cells, the receptor cells in the cochlea, the sound-evoked vibration is transduced to electrical signals and transmitted to the auditory nerve fibers. In the second section it is explained how the electrical activity of these fibers is processed at the cochlear nucleus in order to extract the temporal and level information of sound separately and then transmitted to the third nucleus for processing of the interaural differences, such as the interaural time difference and the interaural level difference. The third section summarizes the transformation of auditory temporal information to the rate of neural firing activity in the midbrain and the higher nuclei, including the cortex, based on in vivo results. Finally, emerging new technologies to investigate auditory signal processing are reviewed and discussed.
