The Role of Internal Noise in Self-Motion Perception


Book Description

In this study, vestibular-based motion perception was investigated. The vestibular system, located in the inner ear, is responsible for sensing translational and rotational motion. A previous study carried out at the University of Toronto found that motion discriminability degraded with increasing motion intensity. Namely, difference thresholds were observed to grow when the amplitude of stimuli increased, suggesting internal noise effects. The current work served as a follow-up to this study and developed a simulation framework to reproduce the results. Analysis of the experiment confirmed that trends in thresholds did not arise due to external motion base noise. Signal detection theory was used as a framework to model the discrimination task and a particle filter perception model was modified to permit the estimation of noise in the otolith, the organ responsible for detecting specific force. Given the limited dataset, simulations successfully reproduced the experimental findings while quantifying the contributions of the internal noise source.




Hearing Loss


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.




Inner Speech


Book Description

Inner Speech focuses on a familiar and yet mysterious element of our daily lives. In light of renewed interest in the general connections between thought, language, and consciousness, this anthology develops a number of important new theories about internal voices and raises questions about their nature and cognitive functions.




Cognitive Behavioral Therapy for Tinnitus


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.

The Vestibular System


Book Description

The Vestibular System is an integrative loo takes an interactive look at the vestibular system and the neurobiology of balance. Written by eight leading experts and headed by Jay M. Goldberg, this book builds upon the classic by Victor Wilson and Geoffrey Melville Jones published over 25 years ago and takes a fresh new look at the vestibular system and the revolutionary advances that have been made in the field.




Vestibular System Part 1: Basic Mechanisms


Book Description

The details of the receptor mechanism are not yet fully understood for any sensory system. However, sufficient data are available (for the vestibular system and for other systems) to permit meaningful tracking of the sensory messages through the nervous system and via conscious experience. The reception, process ing, storage and output of information in man and other animals, as done by means of receptors, neurons, secretory cells and muscle fibers, are collectively referred to as mind. Sensory physiologists tend to disbelieve in extrasensory perception. Sensory physiology in general is an area upon which different sciences and methods converge. Anatomists, physiologists, psychologists, physicists, chemists, and engineers have made important contributions to sensory physiology. What is special about vestibular physiology is the fact that many research workers are clinicians, living under the constant pressure of their patient's demands. This is a disadvantage when it comes to writing handbooks, but an advantage for the pa tient, since research is guided by clinical practice and can be quickly applied. Modern methods, such as recording from single nerve units and the correlation of electrophysiological and psychophysical data, have greatly contributed to our knowledge, yet the study of lesions is still important, especially in the vestibular field.




Handbook of Space Pharmaceuticals


Book Description

This two-volume handbook, directed at medical professionals and students who are involved in developing the space industry or are academicians doing research in this area, covers current pharmaceutical knowledge about the difference in medication efficacy in space versus on Earth and includes trial results and best practices for the space research and travel industry. The well-known contributors come from an interdisciplinary background and address all aspects of the subject, from the physiological impact of spaceflight to the effects of radiation. As the commercial space industry expands its operations in industry and tourism, the field of space pharmaceuticals is growing commensurately. Existing pharmacological research from space is thoroughly covered in this book, and Earth applications are also described. Potential pharmacological solutions are posed along with the known challenges and examples from existing studies, which are detailed at length. This major reference work is a comprehensive and important medical resource for all space industry players.
