The Auditory Brainstem Response


Book Description




Evoked Potential Manual


Book Description

J.P.C. de Weerd Evoked potentials are the electrical voltage fluctuations which can be recorded from parts of the nervous system in response to stimulation of sensory modalities. One may distinguish between evoked potentials from the peripheral and the central nervous system. For the latter type a further subdivision can be made into spinal, brainstem, and cortical evoked potentials, according to the (assumed) structures from which the responses derive. Another possible subdivision can be made with respect to the specific sensory ffiodality which is stimulated. Accordingly, one has auditory, somatosensory, visual, gustatory and olfactory evoked potentials. At the present time, the former three types of evoked potentials are the ones that are commonly measured in diagnostic procedures. Yhe corresponding sensory systems are relatively easy to stimulate, for example by means of an acoustic click, abrief electrical shock or a reversing light pattern. In contrast, stimulation of the olfactory and gustatory systems has proven to be technically and physiologically difficult and research in these areas is still in an early stage.







The Aging Auditory System


Book Description

This volume brings together noted scientists who study presbycusis from the perspective of complementary disciplines, for a review of the current state of knowledge on the aging auditory system. Age-related hearing loss (ARHL) is one of the top three most common chronic health conditions affecting individuals aged 65 years and older. The high prevalence of age-related hearing loss compels audiologists, otolaryngologists, and auditory neuroscientists alike to understand the neural, genetic and molecular mechanisms underlying this disorder. A comprehensive understanding of these factors is needed so that effective prevention, intervention, and rehabilitative strategies can be developed to ameliorate the myriad of behavioral manifestations.







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.







The Auditory System in Sleep


Book Description

The Auditory System in Sleep presents for the first time a view of a sensory system working in a different state-that of the sleeping brain. The auditory system is always "open receiving information from the environment and the body itself (conscious and unconscious data). Even during sleep the auditory information is processed, although in a different way. This book draws information from evoked potentials, fMRI, PET, SPECT, lesions, etc., together with electrophysiological online data in order to depict how the auditory system single unit activity, recorded during sleep, revealed the possibility of sensory information participation in sleep processes. - Presents diverse experimental viewpoints from the beginning of classical electroencephalography to the more recent imaging, single units, electro-magneto-encephalography studies, etc. - Includes classic data as well as new data based in the existing literature and on the long scientific research lines (auditory and sleep) developed by the author and coworkers on this subject since 1963




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.
