Available in PDF, EPUB and Kindle. Book excerpt: Purpose: This study was designed to investigate (1) the effects of age and hearing loss on auditory neural coding, (2) interrelationships between auditory evoked potentials (AEP) taking place at early and later stage of auditory processing, and (3) electrophysiological correlates of age-related declines in speech-in-noise perception. Methods: 30 young normal-hearing adults (YNH, M=21 years), 26 older adults with near-normal hearing (ONH, M=63.9 years) and 26 older adults with hearing loss (OHL, M=72.8 years) participated in the study. AMLR Pa and N1, P2 and N2 of ALLRs were recorded using two-channel electrode system. 500 Hz tone burst and syllable /ba/ were presented in quiet and in babble at the level of 90 Leq (dBA), accompanied by babble at the level of 65 Leq (dBA). Revised Speech Perception in Noise (R-SPIN) test was conducted to measure speech-in-noise perception. Results: ONH listeners demonstrated significantly enhanced Pa and N1 amplitudes and significantly prolonged Pa, P2 and N2 latencies compared with YNH listeners, indicating the effects of aging. OHI group demonstrated significantly prolonged N2 latencies compared with ONH group, indicating the effects of hearing loss. OHI listeners demonstrated significantly enhanced amplitudes and significantly prolonged latencies across all AEP components compared with YNH listeners, indicating that the combined effects may have stronger impacts on age-related changes in AEP morphology. Significant correlations between the amplitudes of Pa and each component of ALLRs were found in ONH and OHI groups, indicating that enhanced Pa amplitudes correspond with enhanced amplitudes of cortical responses in older listeners. Significant correlations between latencies of Pa and each component of ALLRs were found in all groups, indicating that prolonged Pa latencies correspond with prolonged latencies of cortical responses in all listeners. In both ONH and OHI groups, lower R-SPIN-LP scores are significantly correlated with enhanced Pa, P2, and N2 amplitudes and prolonged N2 latencies, particularly for syllable /ba/. Discussion and Conclusions: Interplay between effects of aging and hearing loss may have stronger impacts on morphological changes in the AEP waveforms. Amplitude-based interrelationships reflect age-related changes in a transfer of neural information between subcortical and cortical auditory network. Latency-based interrelationships indicate the association between neural timings at subcortical and cortical levels. Age-related enhancements of Pa, P2 and N2 amplitudes and age-related prolongations of N2 latencies may serve as electrophysiological correlates of age-related declines in SIN perception.

This book was released on 2019-01-03 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Auditory Brain and Age-Related Hearing Impairment provides an overview of the interaction between age-related hearing impairments and cognitive brain function. This monograph elucidates the techniques used in the connectome and other brain-network studies based on electrophysiological methods. Discussions of the manifestations of age-related hearing impairment, the causes of degradation of sound processing, compensatory changes in the human brain, and rehabilitation and intervention are included. There is currently a surge in content on aging and hearing loss, the benefits of hearing aids and implants, and the correlation between hearing loss, cognitive decline and early onset of dementia. Given the changing demographics, treatment of age-related hearing impairment need not just be bottom-up (i.e., by amplification and/or cochlear implantation), but also top-down by addressing the impact of the changing brain on communication. The role of age-related capacity for audio-visual integration and its role in assisting treatment have only recently been investigated, thus this area needs more attention. Relates the techniques used in the connectome and other brain-network studies to the human auditory-cortex and age-related hearing loss research findings Examines the side effects of age-related hearing impairment and their impact on the quality of life for the elderly Evaluates the importance of multi-modal means in the rehabilitation of the elderly with hearing aids and cochlear implants Discusses the role of neurostimulation and various training procedures to halt, or potentially reverse, cognitive decline in the elderly

Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Models for Human Aging is designed as the only comprehensive work available that covers the diversity of aging models currently available. For each animal model, it presents key aspects of biology, nutrition, factors affecting life span, methods of age determination, use in research, and disadvantages/advantes of use. Chapters on comparative models take a broad sweep of age-related diseases, from Alzheimer's to joint disease, cataracts, cancer, and obesity. In addition, there is an historical overview and discussion of model availability, key methods, and ethical issues. - Utilizes a multidisciplinary approach - Shows tricks and approaches not available in primary publications - First volume of its kind to combine both methods of study for human aging and animal models - Over 200 illustrations
Download or read book Handbook of the Neuroscience of Aging written by Patrick R. Hof and published by Academic Press. This book was released on 2010-05-22 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: A single volume of 85 articles, the Handbook of the Neurobiology of Aging is an authoritative selection of relevant chapters from the Encyclopedia of Neuroscience, the most comprehensive source of neuroscience information assembled to date (AP Oct 2008). The study of neural aging is a central topic in neuroscience, neuropsychology and gerontology. Some well-known age-related neurological diseases include Parkinson's and Alzheimer's, but even more common are problems of aging which are not due to disease but to more subtle impairments in neurobiological systems, including impairments in vision, memory loss, muscle weakening, and loss of reproductive functions, changes in body weight, and sleeplessness. As the average age of our society increases, diseases of aging become more common and conditions associated with aging need more attention by doctors and researchers. This book offers an overview of topics related to neurobiological impairments which are related to the aging brain and nervous system. Coverage ranges from animal models to human imaging, fundamentals of age-related neural changes and pathological neurodegeneration, and offers an overview of structural and functional changes at the molecular, systems, and cognitive levels. Key pathologies such as memory disorders, Alzheimer's, dementia, Down syndrome, Parkinson's, and stroke are discussed, as are cutting edge interventions such as cell replacement therapy and deep brain stimulation. There is no other current single-volume reference with such a comprehensive coverage and depth. Authors selected are the internationally renowned experts for the particular topics on which they write, and the volume is richly illustrated with over 100 color figures. A collection of articles reviewing our fundamental knowledge of neural aging, the book provides an essential, affordable reference for scientists in all areas of Neuroscience, Neuropsychology and Gerontology. - The most comprehensive source of up-to-date data on the neurobiology of aging, review articles cover: normal, sensory and cognitive aging; neuroendocrine, structural and molecular factors; and fully address both patholgy and intervention - Chapters represent an authoritative selection of relevant material from the most comprehensive source of information about neuroscience ever assembled, (Encyclopedia of Neuroscience), synthesizing information otherwise dispersed across a number of journal articles and book chapters, and saving researchers the time consuming process of finding and integrating this information themselves - Offering outstanding scholarship, each chapter is written by an expert in the topic area and over 20% of chapters feature international contributors, (representing 11 countries) - Provides more fully vetted expert knowledge than any existing work with broad appeal for the US, UK and Europe, accurately crediting the contributions to research in those regions - Fully explores various pathologies associated with the aging brain (Alzheimer's, dementia, Parkinson's, memory disorders, stroke, Down's syndrome, etc.) - Coverage of disorders and key interventions makes the volume relevant to clinicians as well as researchers - Heavily illustrated with over 100 color figures
