Book Description
The basic measure of an animal's hearing is the behavioral, pure-tone audiogram, which shows an animal's sensitivity to pure tones throughout its hearing range. Because obtaining a behavioral audiogram on an animal can take months, the tone-evoked auditory brainstem response (ABR) is often used instead to obtain thresholds. Although the tone-evoked ABR is obtained quickly and with relative ease, it does not accurately reflect an animal's behavioral sensitivity to pure tones. Because several lines of evidence suggested that using narrow-band noise to evoke the ABR might give a more accurate measure, ABR thresholds evoked by one-octave noise bands and short-duration tones (tone pips) were compared in rats to determine which most closely estimated the animals' behavioral, pure-tone thresholds. The results indicated that although the ABR thresholds evoked by octave-band noise (noise-evoked ABR) were a closer match to behavioral thresholds than those evoked by tone pips (tone-evoked ABR), absolute thresholds still did not provide a sufficiently close estimate of the behavioral audiogram. However, when corrected for the mean difference between the noise-evoked ABR and behavioral thresholds, the noise-evoked ABR did show the potential for estimating high-frequency hearing sensitivity. It should be noted, this finding was a post hoc observation, and requires replication. Three additional findings of this study were: (1) an improved behavioral measure of low-frequency hearing in the laboratory rat, (2) the unexpected finding that damage to the middle ear portion of one ear resulted in transient increased behavioral thresholds for high frequencies in the other ear, and (3) signs of age-related, high-frequency hearing loss that occurred between 14 and 19 months of age.

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.

Book Description
Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

Book Description
Written for auditory clinicians and researchers alike, this is the first monograph on this important area of auditory science that traces the international research effort from its origins in the 1970s to the present day. Comprising contributions from experts in a range of disciplines including auditory physiology, engineering, medicine and audiology, the book presents comprehensive and authoritative coverage of the generation and recording of the ASSR and the clinical applications of the response.

Book Description
Some well-known age-related neurological diseases include Parkinson's disease, Alzheimer's disease, deafness, and blindness. Even more common are the problems of aging which are not due to disease but to more subtle impairments in neurobiological systems, including impairments in vision, memory loss, muscle weakening, and loss of reproductive functions, changes in body weight, and sleeplessness. As the average age of our society increases, diseases of aging continue to become more common, and conditions associated with aging need more attention by doctors and researchers. In 1991, patients over the age of 65 saw their doctors an average of eight times per year. Research funding is provided by the Neuroscience and Neuropsychology of Aging (NNA) Program, which is run by the National Institute on Aging. This book offers a comprehensive overview of all topics related to functional impairments which are related to the aging brain and nervous system. It is organized according to four general functions: movement, senses, memory, and neuroendocrine regulation. Written by the leading researchers in the field, this comprehensive work addresses both impairments associated with diseases and not associated with diseases, making it easier to understand the mechanisms involved. Functional Neurobiology of Aging is an important reference for professionals and students involved in aging research, as well as physicians who need to recognize and understand age-related impairments. Organized by function, making it easy to find and understand the material Addresses impairments both associated with diseases and not associated with diseases Written by leading researchers in the field Most comprehensive source of information on the neurobiology of aging
