Book Description
A detailed report of research on localization of sound in space after transection of auditory pathways in the tectum is given. The ability to localize sound in space was measured in a series of patients who had parts of the temporal lobe removed unilaterally and in patients with removal of cortex of the frontal lobes. One patient, had a right hemispherectomy. Three of the patients with temporal lobe ablation made poorer scores than normal subjects or patients with frontal lobe damage. The others made scores as good as some normal subjects. The patient with right hemispherectomy localized a noise source with surprising accuracy, an average error (for light spot placed at estimated source of sound) of about 5 degrees. There was some tendency for localization to be poorer in the auditory field opposite the side of lesion. An attempt was made to discover the areas of association cortex of the temporal lobes that are involved in learning auditory and visual discriminations. In the cat, isolation of auditory areas AI, AII, and Ep from insular-temporal and from other cortex by ablating a band of insular-temporal and from other cortex by ablating a band of surrounding cortical tissue does not affect pattern discrimination. There is no temporary amnesia for the learned habit. In the monkey, new experiments confirmed the finding of earlier experiments that auditory pattern discrimination is impaired but can be relearned after bilateral removal of the anterior part of the superior surface of the superior temporal convolution, a region of cortex that receives projection from the dorsal posterior portion of the lateral geniculate body.

nerve; subsequently, however, they concluded that the recordings had been from aberrant cells of the cochlear nucleus lying central to the glial margin of the VIII nerve (GALAMBOS and DAVIS, 1948). The first successful recordmgs from fibres of the cochlear nerve were made by TASAKI (1954) in the guinea pig. These classical but necessarily limited results were greatly extended by ROSE, GALAMBOS, and HUGHES (1959) in the cat cochlear nucleus and by KATSUKI and co-workers (KATSUKI et at. , 1958, 1961, 1962) in the cat and monkey cochlear nerve. Perhaps the most significant developments have been the introduction of techniques for precise control of the acoustic stimulus and the quantitative analysis of neuronal response patterns, notably by the laboratories of KIANG (e. g. GERSTEIN and KIANG, 1960; KIANG et at. , 1962b, 1965a, 1967) and ROSE (e. g. ROSE et at. , 1967; HIND et at. , 1967). These developments have made possible a large number of quanti tative investigations of the behaviour of representative numbers of neurons at these levels of the peripheral auditory system under a wide variety of stimulus conditions. Most of the findings discussed herein have been obtained on anaesthetized cats. Where comparative data are available, substantially similar results have been obtained in other mammalian species (e. g. guinea pig, monkey, rat). Certain significant differences have been noted in lizards, frogs and fish as would be expect ed from the different morphologies of their organs of hearing (e. g.

The Human Auditory Cortex

ISBN: 1461423139

Languages : en
Pages : 404
Book Description
We live in a complex and dynamically changing acoustic environment. To this end, the auditory cortex of humans has developed the ability to process a remarkable amount of diverse acoustic information with apparent ease. In fact, a phylogenetic comparison of auditory systems reveals that human auditory association cortex in particular has undergone extensive changes relative to that of other species, although our knowledge of this remains incomplete. In contrast to other senses, human auditory cortex receives input that is highly pre-processed in a number of sub-cortical structures; this suggests that even primary auditory cortex already performs quite complex analyses. At the same time, much of the functional role of the various sub-areas in human auditory cortex is still relatively unknown, and a more sophisticated understanding is only now emerging through the use of contemporary electrophysiological and neuroimaging techniques. The integration of results across the various techniques signify a new era in our knowledge of how human auditory cortex forms basis for auditory experience. This volume on human auditory cortex will have two major parts. In Part A, the principal methodologies currently used to investigate human auditory cortex will be discussed. Each chapter will first outline how the methodology is used in auditory neuroscience, highlighting the challenges of obtaining data from human auditory cortex; second, each methods chapter will provide two or (at most) three brief examples of how it has been used to generate a major result about auditory processing. In Part B, the central questions for auditory processing in human auditory cortex are covered. Each chapter can draw on all the methods introduced in Part A but will focus on a major computational challenge the system has to solve. This volume will constitute an important contemporary reference work on human auditory cortex. Arguably, this will be the first and most focused book on this critical neurological structure. The combination of different methodological and experimental approaches as well as a diverse range of aspects of human auditory perception ensures that this volume will inspire novel insights and spurn future research.

Languages : en
Pages : 438
Book Description
The Springer Handbook of Auditory Research presents a series of com prehensive and synthetic reviews of the fundamental topics in modern auditory research. It is aimed at all individuals with interests in hearing research including advanced graduate students, postdoctoral researchers, and clinical investigators. The volumes will introduce new investigators to important aspects of hearing science and will help established inves tigators to better understand the fundamental theories and data in fields of hearing that they may not normally follow closely. Each volume is intended to present a particular topic comprehensively, and each chapter will serve as a synthetic overview and guide to the literature. As such, the chapters present neither exhaustive data reviews nor original research that has not yet appeared in peer-reviewed journals. The series focusses on topics that have developed a solid data and con ceptual foundation rather than on those for which a literature is only beginning to develop. New research areas will be covered on a timely basis in the series as they begin to mature.
Primate Audition

Pages : 333
Book Description
Bringing together the knowledge of world experts on different aspects of primate auditory function, this book bridges the epistemological gap between primate ethologists and auditory neurobiologists. Leading ethologists, comparative psychologists, and neuroscientists who have developed new experimental approaches apply their methods to a variety of issues dealing with primate vocal behavior and the neurobiology of the primate auditory system. The synthesis of ethological and neurobiological approaches to primate vocal behavior presented in this book will yield a rich understanding of the acoustic and neural bases of primate audition and shed light on the evolutionary precursors to speech.
