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.
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 Age related Changes in Auditory Temporal Processing written by Jacqueline Alexandra Overton and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Age-related hearing loss (ARHL) is the third most prevalent cause of disability in adults over age 65. However, we still do not have an adequate understanding of the mechanisms underlying ARHL. The primary complaint of those with ARHL is a difficulty comprehending speech, particularly in challenging listening environments. This can lead to social isolation, depression and contribute to cognitive decline. Importantly, impairments in speech processing and comprehension occur even in the absence of measurable changes in hearing thresholds. Similarly, speech comprehension difficulties are often not corrected with hearing aids. Understanding age-related changes in temporal processing in the central auditory system is critical to understanding the neural mechanisms of speech processing deficits associated with ARHL. This is the central question of my thesis.There are five chapters in this dissertation. In Chapter 1, I introduce the thesis with an overview of ARHL, and a review of the literature covering age related changes in speech and temporal processing, and age-related changes in the central auditory pathway. In Chapter 2, I present single-unit electrophysiology data recorded from primary auditory cortex (A1) in older rhesus macaque monkeys in response to amplitude modulated (AM) broadband noise presented across a range of modulation frequencies, and compare those data with the results from younger monkeys reported previously in Yin and colleagues (2011). This was the first study of age-related changes in cortical auditory temporal processing in the macaque. I found that neurons from older monkeys show dramatic changes in their responses to AM noise as measured by their ability to phase-lock to the envelope and by their overall firing rate. Several measures of tuning were correlated in young monkeys, but these relationships were either reversed, or lost in units from older monkeys. Underlying these changes was a decrease in the ability of older neurons to phase-lock to the envelope of an AM stimulus, and dramatically increased spontaneous and evoked firing rates (replicated from previous studies). These data, however, were collected under passive stimulus presentation conditions, so it is unclear how these changes affect the ability to accurately represent the stimulus. The logical follow-up to the study presented in Chapter 2, is to record from single units in macaque A1 while they are performing a task that requires them to attend to and make decisions regarding a specific attribute of the AM stimulus (in this case modulation frequency). I, therefore, designed a two-alternative forced choice (2AFC) AM frequency discrimination task for this purpose. How modulation frequency discrimination ability may change with age had not been tested previously. Hence, in Chapter 3, I present psychophysical data from a cross-sectional sample of 33 human participants ranging in age from 25 to 80 years, and compare those data to results from one 16-year old macaque. I found an age-related decline in AM frequency discrimination at the highest AM frequencies measured, but no age-related difference in performance at lower frequencies. Importantly, age-related changes in discrimination ability were not related to hearing thresholds, further supporting that age-related temporal processing deficits are due to changes in the central auditory system independent of peripheral changes. Comparison to monkey data showed that human subjects’ discrimination ability was more acute overall, and extended to temporal frequencies beyond the monkey’s upper limit of AM frequency discrimination. This result suggests a perceptual specialization in humans for fine changes in temporal frequency that is likely to be relevant to speech processing. This section of the thesis is concluded in Chapter 4, where I discuss the implications of results presented in the previous two chapters in the context of the introductory chapter, and offer directions for future research. Cranial implants are a necessary component of neurophysiological investigation of nonhuman primates. In Chapter 5, I present a methodology for implanting nonhuman primates with custom-fitted acrylic-free headposts and recording cylinders using biocompatible materials. Each titanium headpost was hand-form to fit a 3D-printed replica of the animal’s skull, which was created from CT data. I provide a timeline and detail each step of the process, including information for converting DICOM data to a 3D-printable format. Furthermore, I discuss issues of biocompatibility of materials, and suggest procedures for promoting osseointegration of titanium implants. Overall, these methods have proven to reduce implant surgery times up to 70%. All implanted headposts remained intact and free of infection for the experimental life of each animal (four years and counting).

Download or read book Auditory Spectral Processing written by Manuel S. Malmierca and published by Gulf Professional Publishing. This book was released on 2005-11-23 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: All natural auditory signals, including human speech and animal communication signals, are spectrally and temporally complex, that is, they contain multiple frequencies and their frequency composition, or spectrum, varies over time. The ability of hearers to identify and localize these signals depends on analysis of their spectral composition. For the overwhelming majority of human listeners spoken language is the major means of social communication, and this communication therefore depends on spectral analysis. Spectral analysis begins in the cochlea, but is then elaborated at various stages along the auditory pathways in the brain that lead from the cochlea to the cerebral cortex. The broad purpose of Auditory Spectral Processing is to provide a comprehensive account of the way in which spectral information is processed in the brain and the way in which this information is used by listeners to identify and localize sounds. Examines spectral processing mechanisms at different levels along the auditory neuraxis, from the cochlear nucleus to the cortex Reviews in detail psychophysical and neurophysiological evidence on the way in which spectral information is processed within and across frequency channels Presents information on the nature of the spectral information required for speech and music perception Examines a series of issues that relate to the role of spectral analysis in higher order/cognitive aspects of hearing and in clinical and applied contexts

Download or read book Neural Correlates of Auditory Cognition written by Yale E. Cohen and published by Springer Science & Business Media. This book was released on 2012-10-20 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hearing and communication present a variety of challenges to the nervous system. To be heard and understood, a communication signal must be transformed from a time-varying acoustic waveform to a perceptual representation to an even more abstract representation that integrates memory stores with semantic/referential information. Finally, this complex, abstract representation must be interpreted to form categorical decisions that guide behavior. Did I hear the stimulus? From where and whom did it come? What does it tell me? How can I use this information to plan an action? All of these issues and questions underlie auditory cognition. Since the early 1990s, there has been a re-birth of studies that test the neural correlates of auditory cognition with a unique emphasis on the use of awake, behaving animals as model. Continuing today, how and where in the brain neural correlates of auditory cognition are formed is an intensive and active area of research. Importantly, our understanding of the role that the cortex plays in hearing has the potential to impact the next generation of cochlear- and brainstem-auditory implants and consequently help those with hearing impairments. Thus, it is timely to produce a volume that brings together this exciting literature on the neural correlates of auditory cognition. This volume compliments and extends many recent SHAR volumes such as Sound Source Localization (2005) Auditory Perception of Sound Sources (2007), and Human Auditory Cortex (2010). For example, in many of these volumes, similar issues are discussed such as auditory-object identification and perception with different emphases: in Auditory Perception of Sound Sources, authors discuss the underlying psychophysics/behavior, whereas in the Human Auditory Cortex, fMRI data are presented. The unique contribution of the proposed volume is that the authors will integrate both of these factors to highlight the neural correlates of cognition/behavior. Moreover, unlike other these other volumes, the neurophysiological data will emphasize the exquisite spatial and temporal resolution of single-neuron [as opposed to more coarse fMRI or MEG data] responses in order to reveal the elegant representations and computations used by the nervous system.

Download or read book Temporal Processing in Primate Auditory Cortex written by Daniel Bendor and published by LAP Lambert Academic Publishing. This book was released on 2011-03 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cornerstone of the human auditory system is its ability to recognize and appreciate music and speech. At its most basic level, music is made up of melodies and rhythms, which are the relative changes in pitch and temporal rates, respectively, for a series of musical notes. Speech is also composed of sequences of different pitches and temporal rates, however pitch changes carry prosody information (for non-tonal languages), while semantic information in contained in the temporal rate. How is an acoustic signal's temporal rate and pitch encoded in the auditory system? For my dissertation, I have investigated the neural coding of a sound's temporal properties by single neurons in the auditory cortex of the marmoset.
