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
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
At a level for doctoral or medical students in neurosciences, audiology, or physiology, Physiology of the Ear, 2E has brought together in a complete and concise manner a compilation of articles written by experts in their specialty and addressing clinical and basic science aspects of ear physiology. The text begins with a history of the discovery of the anatomy and physiology of the ear and works systematically from the external, middle, and inner ear to the brain. Easy to read and understand, this text can be used as a resource or as a tool for study and review. It covers topics such as sound and bone conduction mechanisms, signal processing, stimulus coding in the auditory system, blood circulation of the cochlea, and auditory brain mapping. It highlights the application of new research findings to the management problems encountered in everyday practice, and covers important aspects of nonauditory physiology such as skin migration in the ear canal.

Book Description
Connecting the auditory brain stem to sensory, motor, and limbic systems, the inferior colliculus is a critical midbrain station for auditory processing. Winer and Schreiner's The Inferior Colliculus, a critical, comprehensive reference, presents the current knowledge of the inferior colliculus from a variety of perspectives, including anatomical, physiological, developmental, neurochemical, biophysical, neuroethological and clinical vantage points. Written by leading researchers in the field, the book is an ideal introduction to the inferior colliculus and central auditory processing for clinicians, otolaryngologists, graduate and postgraduate research workers in the auditory and other sensory-motor systems.

Book Description
For many individuals afflicted with tinnitus, the condition causes substantial distress. While there is no known cure for tinnitus, cognitive behavioral therapy (CBT) can offer an effective strategy for managing the symptoms and side effects of chronic tinnitus. Cognitive Behaviorial Therapy for Tinnitus is the first book to provide comprehensive CBT counseling materials specifically developed for the management of tinnitus. This valuable professional book has two primary purposes: to provide clinical guidelines for audiologists who are offering CBT-based counseling for tinnitus and to provide self-help materials for individuals with tinnitus. In addition, these materials may be of interest to researchers developing evidence-based therapies for tinnitus. The book is structured into three sections. Section A provides background information about the theoretical aspects of CBT and some practical tips on how to use this book. Section B provides the CBT counseling, or self-help materials, which can be used by both audiologists and those with tinnitus. Finally, Section C provides some supplementary materials for clinicians that can aid monitoring and engagement of individuals experiencing tinnitus during the course of intervention. Key Features: * The CBT materials contained in this text have been tested in numerous clinical trials across the globe (Australia, Germany, Sweden, United Kingdom, and the United States) both as self-help book chapters and self-help materials delivered via the Internet. * The counseling materials are presented at minimum reading grade level (U.S. 6th grade level) to maximize reader engagement. * The authors of this book have extensive experience in the management of tinnitus, offering useful insights for clinicians and those with tinnitus. * Includes expert advice videos for each chapter to facilitate its adoption to clinical practice.

Book Description
This book systematically discusses the pathogenesis, prevention, and the current and potential clinical treatment of hearing loss, as well as the latest advances in hearing research. Hearing loss is a prevalent sensory disorder, which according to a 2015 World Health Organization (WHO) report affected 9% of the global population in 2015. As populations continue to age, more and more people are suffering from the condition, with 60% of those aged between 65 and 75 affected. Hearing loss seriously affects patients’ ability to work ability and quality of life, and as such deafness has become an increasingly urgent social problem around the globe. Sensorineural hearing loss is mainly caused by damage to the hair cells (HCs), and the subsequent loss of spiral ganglion neurons (SGNs). Damage to the HCs in the inner ear can result from exposure to loud noises and environmental and chemical toxins as well as genetic disorders, aging, and certain medications. This book provides ENT specialists and researchers, as well as individuals affected a comprehensive introduction to the field of hearing loss.
