Book Description
Efficient auditory processing requires the rapid integration of transient sensory inputs. This is exemplified in human speech perception, in which long stretches of a complex acoustic signal are typically processed accurately and essentially in real-time. Spoken language thus presents listeners’ auditory systems with a considerable challenge even when acoustic input is clear. However, auditory processing ability is frequently compromised due to congenital or acquired hearing loss, or altered through background noise or assistive devices such as cochlear implants. How does loss of sensory fidelity impact neural processing, efficiency, and health? How does this ultimately influence behavior? This Research Topic explores the neural consequences of hearing loss, including basic processing carried out in the auditory periphery, computations in subcortical nuclei and primary auditory cortex, and higher-level cognitive processes such as those involved in human speech perception. By pulling together data from a variety of disciplines and perspectives, we gain a more complete picture of the acute and chronic consequences of hearing loss for neural functioning.

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.

Book Description
We live in an aging world. Illnesses that are prevalent and cause significant morbidity and mortality in older people will consume an increasing share of health care resources. One such illness is depression. This illness has a particularly devastating impact in the elderly because it is often undiagnosed or inadequately treated. Depression not only has a profound impact on quality of life but it is associated with an increased risk of mortality from suicide and vascular disease. In fact for every medical illness studied, e.g. heart disease, diabetes, cancer, individuals who are depressed have a worse prognosis. Research has illuminated the physiological and behavioral effects of depression that accounts for these poor outcomes. The deleterious relationship between depression and other illnesses has changed the concept of late-life depression from a "psychiatric disorder" that is diagnosed and treated by a psychiatrist to a common and serious disorder that is the responsibility of all physicians who care for patients over the age of 60. This is the first volume devoted to the epidemiology, phenomenology, psychobiology, treatment and consequences of late-life depression. Although much has been written about depressive disorders, the focus has been primarily on the illness as experienced in younger adults. The effects of aging on the brain, the physiological and behavioral consequences of recurrent depression, and the impact of other diseases common in the elderly, make late-life depression a distinct entity. There is a compelling need for a separate research program, specialized treatments, and a book dedicated to this disorder. This book will be invaluable to psychiatrists, gerontologists, clinical psychologists, social workers, students, trainees, and others who care for individuals over the age of sixty.

Book Description
The field of Binaural Hearing involves studies of auditory perception, physiology, and modeling, including normal and abnormal aspects of the system. Binaural processes involved in both sound localization and speech unmasking have gained a broader interest and have received growing attention in the published literature. The field has undergone some significant changes. There is now a much richer understanding of the many aspects that comprising binaural processing, its role in development, and in success and limitations of hearing-aid and cochlear-implant users. The goal of this volume is to provide an up-to-date reference on the developments and novel ideas in the field of binaural hearing. The primary readership for the volume is expected to be academic specialists in the diverse fields that connect with psychoacoustics, neuroscience, engineering, psychology, audiology, and cochlear implants. This volume will serve as an important resource by way of introduction to the field, in particular for graduate students, postdoctoral scholars, the faculty who train them and clinicians.

Book Description
It has become accepted in the neuroscience community that perception and performance are quintessentially multisensory by nature. Using the full palette of modern brain imaging and neuroscience methods, The Neural Bases of Multisensory Processes details current understanding in the neural bases for these phenomena as studied across species, stages of development, and clinical statuses. Organized thematically into nine sub-sections, the book is a collection of contributions by leading scientists in the field. Chapters build generally from basic to applied, allowing readers to ascertain how fundamental science informs the clinical and applied sciences. Topics discussed include: Anatomy, essential for understanding the neural substrates of multisensory processing Neurophysiological bases and how multisensory stimuli can dramatically change the encoding processes for sensory information Combinatorial principles and modeling, focusing on efforts to gain a better mechanistic handle on multisensory operations and their network dynamics Development and plasticity Clinical manifestations and how perception and action are affected by altered sensory experience Attention and spatial representations The last sections of the book focus on naturalistic multisensory processes in three separate contexts: motion signals, multisensory contributions to the perception and generation of communication signals, and how the perception of flavor is generated. The text provides a solid introduction for newcomers and a strong overview of the current state of the field for experts.

Book Description
The loss of hearing - be it gradual or acute, mild or severe, present since birth or acquired in older age - can have significant effects on one's communication abilities, quality of life, social participation, and health. Despite this, many people with hearing loss do not seek or receive hearing health care. The reasons are numerous, complex, and often interconnected. For some, hearing health care is not affordable. For others, the appropriate services are difficult to access, or individuals do not know how or where to access them. Others may not want to deal with the stigma that they and society may associate with needing hearing health care and obtaining that care. Still others do not recognize they need hearing health care, as hearing loss is an invisible health condition that often worsens gradually over time. In the United States, an estimated 30 million individuals (12.7 percent of Americans ages 12 years or older) have hearing loss. Globally, hearing loss has been identified as the fifth leading cause of years lived with disability. Successful hearing health care enables individuals with hearing loss to have the freedom to communicate in their environments in ways that are culturally appropriate and that preserve their dignity and function. Hearing Health Care for Adults focuses on improving the accessibility and affordability of hearing health care for adults of all ages. This study examines the hearing health care system, with a focus on non-surgical technologies and services, and offers recommendations for improving access to, the affordability of, and the quality of hearing health care for adults of all ages.

Book Description
The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Book Description
Dementia, technically defined as cognitive impairments sufficiently pervasive and severe enough that they disrupt independent life, is one of the most devastating symptoms of neurologic disease. While Alzheimer's disease (AD) is the most common neurodegenerative disease that causes it, more than 50 medical, psychiatric, and neurological conditions are associated with dementia. Well organized and expertly planned, this text provides new concepts of patient management that have come about through recent neuroscience research. This volume, reviewing the dementias with the needs of the clinician in mind, is unique in that the section dealing with disease mechanisms reviews the exciting recent scientific advance in regard to Alzheimer disease, whereas the clinical section(section A) focuses not on Alzheimer disease but upon related disorders, the less common dementing syndromes due to other neurodegenerative disorders. The editors of this Blue Book have brought together an extraordinary group of experts to define the scientific advances primarily in Alzheimer's disease (section B) and new treatments (section C) being developed. * Written for non-expert general neurologists and residents * Provides new concepts of patient management discovered in neuroscience research * Includes unique coverage of recent scientific advances in Alzheimer's Disease
