This book was released on 2014 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: One way of structuring the huge amount of sound input reaching the human ear, is extracting sound objects, which are formed by stimuli having a certain regularity in common. Mismatching stimuli are detected pre-attentively and can trigger an involuntary attention switch towards them. The auditory-event related potential which reflects the process of detecting mismatching sounds is called mismatch negativity (03N), usually peaks at 150 to 250 ms from stimulus onset and has bilateral sources in auditory and prefrontal cortex. 03N is elicited by deviants violating auditory regularities, like in a simple "oddball paradigm", which is composed of unchanging repetitive "standard" sounds and rare, randomly occurring, deviating sounds (so called deviants), as well as by violations of more complex auditory regularities. Recently it has been shown that also the middle latency response (MLR), which is an earlier auditory evoked potential (AEP), reflects the occurrence of deviating sounds in an oddball paradigm. The objective of the present thesis was to examine the role of the middle latency response in the auditory deviance detection system. The first study showed that lower intensity deviants of an oddball paradigm elicited a slight negativity at the transition from the Na to the Pa wave, in comparison to the response elicited by physically identical standard stimuli. In addition, an 03N was elicited. In the second study a hypercomplex invariance, more concretely, a feature-conjunction paradigm with two types of standard stimuli, each with a distinct combination of stimulus frequency and stimulus source location, and two types of deviant stimuli, each with the frequency of one standard stimulus, and the location of the other, were presented. In order to compare the results with MLRs elicited by stimuli of a simple auditory regularity, an additional simple oddball paradigm with frequency deviants was presented. The Nb wave of the MLR was enhanced in response to frequency deviants compared to standard stimuli of the simple oddball paradigm. However, comparison of the MLRs to deviants and standards of the feature-conjunction paradigm yielded no differences. An 03N was elicited in both paradigms. In the third study the application of a variation of the multi-feature paradigm for MLR studies and the MLR in response to frequency-intensity double deviants were probed. Frequency-intensity double deviants elicited a significant enhancement of the MLR, which was as large as the sum of the enhancements elicited by the frequency and intensity single deviants. The results of the present thesis suggest that the early deviance detection at the level of the MLR occurs only for simple auditory regularities, as in the case of feature repetitions in the simple oddball paradigm, or in the multi-feature paradigm, where formation of the standard trace does not require extracting feature-combinations. Furthermore, the results suggest that deviations in frequency and intensity are processed independently from each other. Based on evidence from the present thesis and from other studies, we conclude that the regularity encoding and deviance detection of stimuli presented in more complex auditory regularities than the simple oddball or the multi-feature paradigm require higher-order brain mechanisms than those reflected in the MLR. This goes in line with the hypothesis of a hierarchically organized auditory novelty system. Concerning the cellular mechanisms underlying auditory deviance detection, it has been proposed that stimulus-specific adaptation (SSA) to stimulus probabilities observed in animal auditory subcortical and cortical structures could be the single neuron correlate of the deviance-related activity in the human AEP due to its similar characteristics to 03N. However, since the latencies of the MLR better match the latencies of SSA, it is probable that the deviance-related modulations in the MLR represent a more direct correlate of the early cellular SSA, than 03N.

This book was released on 2010-03-23 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the 15th International Symposium on Hearing (ISH), which was held at the Hotel Regio, Santa Marta de Tormes, Salamanca, Spain, between 1st and 5th June 2009. Since its inception in 1969, this Symposium has been a forum of excellence for debating the neurophysiological basis of auditory perception, with computational models as tools to test and unify physiological and perceptual theories. Every paper in this symposium includes two of the following: auditory physiology, psychoph- ics or modeling. The topics range from cochlear physiology to auditory attention and learning. While the symposium is always hosted by European countries, p- ticipants come from all over the world and are among the leaders in their fields. The result is an outstanding symposium, which has been described by some as a “world summit of auditory research. ” The current volume has a bottom-up structure from “simpler” physiological to more “complex” perceptual phenomena and follows the order of presentations at the meeting. Parts I to III are dedicated to information processing in the peripheral au- tory system and its implications for auditory masking, spectral processing, and c- ing. Part IV focuses on the physiological bases of pitch and timbre perception. Part V is dedicated to binaural hearing. Parts VI and VII cover recent advances in und- standing speech processing and perception and auditory scene analysis. Part VIII focuses on the neurophysiological bases of novelty detection, attention, and learning.

Download or read book Auditory Temporal Processing and its Disorders written by Jos J. Eggermont and published by OUP Oxford. This book was released on 2015-04-30 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Auditory temporal processing' determines our understanding of speech, our appreciation of music, our ability to localize a sound source, and even to listen to a person in a noisy crowd. Sound is dynamic and as such has temporal and spectral content. In disorders such as auditory neuropathy and MS, problems can occur with these temporal representations of sound, leading to a mismatch between auditory sensitivity and speech discrimination. In dyslexia, specific language impairment, and auditory processing disorders, similar problems occur early in life and set up additional cognitive speech processing problems. It has also been found that in disorders such as autism, schizophrenia and epilepsy, temporal processing deficits can occur. This book reviews comprehensively the mechanisms for temporal processing in the auditory system, looking at how these underlie specific clinical disorders, with implications for their treatment. Written by a prolific researcher in auditory neuroscience, this book is valuable for auditory neuroscientists, audiologist, neurologists, and speech language pathologists.

Download or read book The Oxford Handbook of the Auditory Brainstem written by Karl Kandler PhD and published by Oxford University Press. This book was released on 2019-08-22 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Oxford Handbook of The Auditory Brainstem provides an introduction as well as an in-depth reference to the organization and function of ascending and descending auditory pathways in the mammalian brainstem. Individual chapters are organized along the auditory pathway beginning with the cochlea and ending with the auditory midbrain. Each chapter provides an introduction to the respective area, and summarizes our current knowledge before discussing disputes and challenges the field currently faces. A major emphasis throughout this book is on the numerous forms of plasticity that are increasingly observed in many areas of the auditory brainstem. Several chapters focus on neuronal modulation of function and synaptic, neuronal, and circuit plasticity, especially under circumstances when they occur most prominently: during development, aging, and following peripheral hearing loss. In addition, the book addresses the role of trauma-induced maladaptive plasticity with respect to its contribution in generating central hearing dysfunction such as hyperacusis and tinnitus. The book is intended for students and postdocs starting in the auditory field, and researchers of related fields who wish to get an authoritative and up-to-date summary of the current state of auditory brainstem research. For clinical practitioners in audiology, otolaryngology, and neurology, the book is a valuable resource of information about the neuronal mechanisms that are major candidates for the generation of central hearing dysfunction.

Download or read book Human Auditory Evoked Potentials written by Terence W. Picton and published by Plural Publishing. This book was released on 2010-09-01 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Human Auditory Cortex written by David Poeppel and published by Springer Science & Business Media. This book was released on 2012-04-12 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2010-01-21 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 1: The Ear (edited by Paul Fuchs) Volume 2: The Auditory Brain (edited by Alan Palmer and Adrian Rees) Volume 3: Hearing (edited by Chris Plack) Auditory science is one of the fastest growing areas of biomedical research. There are now around 10,000 researchers in auditory science, and ten times that number working in allied professions. This growth is attributable to several major developments: Research on the inner ear has shown that elaborate systems of mechanical, transduction and neural processes serve to improve sensitivity, sharpen frequency tuning, and modulate response of the ear to sound. Most recently, the molecular machinery underlying these phenomena has been explored and described in detail. The development, maintenance, and repair of the ear are also subjects of contemporary interest at the molecular level, as is the genetics of hearing disorders due to cochlear malfunctions.
