Book Description
[Truncated abstract] The mammalian inner ear is innervated by the efferent olivocochlear system which is divided into medial and lateral systems. In anaesthetised animals, medial olivocochlear (MOC) axons can be electrically stimulated at the floor of the IVth ventricle. MOC stimulation suppresses the spontaneous activity and sound-evoked responses of primary afferents by its actions on outer hair cells. Effects of MOC stimulation have been also reported on responses of neurons in the cochlear nucleus, the first central auditory center receiving cochlear input. However, very little is known about the net results of MOC effects in higher order neurons. This issue was investigated by electrically stimulating MOC axons at the IVth ventricle and recording extracellular single unit activities in the central nucleus of the inferior colliculus (CNIC) of anaesthetised guinea pigs. For the first part of the study, anatomical and neurophysiological studies were carried out to establish that the focal midline MOC stimulation can selectively stimulate MOC axons without any current spread to adjacent ascending fibers. The MOC stimulation and CNIC recordings were then carried out in a series of experiments that included normal hearing animals, animals treated acutely with gentamicin (in which the acetylcholine-mediated peripheral suppression of the olivocochlear efferents is selectively eliminated) and partially deafened animals. ... However, in other CNIC neurons, effects could not be so explained, showing either additional suppression or even marked excitatory effects. (4) MOC stimulation also suppressed the spontaneous activity of CNIC neurons in normal hearing animals. When similar efferent stimulation was carried out in partially deafened animals, the abnormally high spontaneous activity of some CNIC neurons in the deafened frequency regions was also transiently suppressed by MOC shocks. The results from this study clearly demonstrate that the MOC system can modulate the responses of midbrain neurons in a more complex manner compared to the effects seen in the periphery. The more complex effects seen for responses to tones in quiet and in noisy background are likely to result from a complex interplay between altered afferent input in the cochlea and central circuitry. In addition, the ability of MOC efferents in suppressing the normal and abnormal spontaneous activity in the midbrain also could have implications for the role of the descending system in the pathophysiology and treatment of tinnitus.

Book Description
Connecting the auditory brain stem to sensory, motor, and limbic systems, the inferior colliculus is a critical midbrain station for auditory processing. Winer and Schreiner's The Inferior Colliculus, a critical, comprehensive reference, presents the current knowledge of the inferior colliculus from a variety of perspectives, including anatomical, physiological, developmental, neurochemical, biophysical, neuroethological and clinical vantage points. Written by leading researchers in the field, the book is an ideal introduction to the inferior colliculus and central auditory processing for clinicians, otolaryngologists, graduate and postgraduate research workers in the auditory and other sensory-motor systems.

Book Description
There has been substantial progress in understanding the contributions of the auditory forebrain to hearing, sound localization, communication, emotive behavior, and cognition. The Auditory Cortex covers the latest knowledge about the auditory forebrain, including the auditory cortex as well as the medial geniculate body in the thalamus. This book will cover all important aspects of the auditory forebrain organization and function, integrating the auditory thalamus and cortex into a smooth, coherent whole. Volume One covers basic auditory neuroscience. It complements The Auditory Cortex, Volume 2: Integrative Neuroscience, which takes a more applied/clinical perspective.

Book Description
This volume represents edited material that was presented at a conference on brainstem modulation of spinal nociception held in Beaune, France during July, 1987. Pain Modulation, Volume 77 in the series Progress in Brain Research reviews, analyses and suggests new research strategies on several relevant topics including: the endogenous opioid peptides; sites of action of opiates; the role of biogenic animes and non-opioid peptides in analgesia; dorsal horn circuitry; behavioural factors in the activation of pain modulating networks and clinical studies of nociceptive modulation.

Book Description
Knowledge about the structure and function of the inner ear is vital to an understanding of vertebrate hearing. This volume presents a detailed overview of the mammalian cochlea from its anatomy and physiology to its biophysics and biochemistry. The nine review chapters, written by internationally distinguished auditory researchers, provide a detailed and unified introduction to sound processing in the cochlea and the steps by which the ensuing signals are prepared for the central nervous system.

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.
