Book Description
The three manuscripts presented herein examine the use of vestibular perceptual thresholds to assess vestibular processing in health and disease. The first manuscript assesses linear motion perception, mediated by the otoliths in the vestibular system, in healthy vestibular function to identify factors influencing vestibular perception. Results suggested that orientation relative to gravity influenced perceptual sensitivity, as earth-vertical (i.e., motions parallel to gravity) thresholds were overall higher than earth-horizontal (i.e., motions perpendicular to gravity) thresholds and previously reported differences in thresholds on the basis of body orientation may largely capture the influence of orientation relative to gravity. Additionally, differences in motion perception on the basis of motion relative to the head were noted, as thresholds with predominant utricular contributions were significantly impacted by orientation relative to gravity and overall lower than thresholds with predominant saccular contributions. In the second manuscript, translation perception was assessed in two patients with complete bilateral vestibular loss in order to verify vestibular contributions to linear motion perception. In the absence of vestibular function, thresholds were overall elevated, suggesting predominant vestibular contributions to whole body direction recognition tasks. A significant elevation in earth-vertical thresholds was also identified, suggesting internal models of gravity are impaired secondary to peripheral vestibular dysfunction leading to decreases sensory precision. Finally, in the third manuscript, motion perception was assayed in persistent postural-perceptual dizziness (PPPD), a common cause of chronic dizziness. Overall, results suggested that motion perception was largely preserved in PPPD as vestibular thresholds were undistinguishable from age-matched controls. However, elevated roll tilt thresholds, which are reliant on canal-otolith integration, were identified in a subset of patients suggesting impaired intra-vestibular integration. Overall, vestibular perceptual thresholds provide unique insights into motion processing and are capable of identifying changes in peripheral and central vestibular function.

Book Description
An introductory reference on balance function testing for clinicians and technicians who assess patients with balance system disorders. Part I provides a historical framework for understanding the evolution of balance function testing. Part II begins with an overview of the anatomy and physiology of the vestibular system and principles of electro-oculography, then focuses on subtests comprising the ENG test battery. Parts III and IV describe rotational and CDP test techniques, and Part V addresses special issues such as medical and surgical treatment and assessment. Includes bandw diagrams.

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.

Book Description
Vertigo, dizziness, and imbalance rank amongst the most common presenting symptoms in neurology, ENT, geriatric medicine, and general practice. These symptoms can originate from many different organs and systems, such as the inner ear, general medical conditions, neurological and psychological disorders. The Oxford Textbook of Vertigo and Imbalance provides an up-to-date summary of the scientific basis, clinical diagnosis, and management of disorders leading to dizziness and poor balance. This textbook is conceptually divided into three sections, detailing the scientific basis, general clinical issues, and specific diseases diagnosed in clinical practice that are responsible for complaints of dizziness and imbalance. Individual chapters address benign paroxysmal positional vertigo, vestibular migraine, vestibular neuritis, stroke, and Ménière's disease. Additional chapters follow a syndrome-based approach and cover multiple conditions, including cerebellar disorders, bilateral vestibular failure and gait, and psychological disorders. The print edition is complemented by an online version, which allows access to the full content of the textbook, contains links from the references to primary research journal articles, allows full text searches, and provides access to figures and tables that can be downloaded to PowerPoint. It serves a useful clinical reference for neurologists, otorhinolaryngologists, audio-vestibular physicians, and senior trainees in those specialties.

Book Description
Robert Arking's Biology of Aging is an introductory text to the biology of aging which gives advanced undergraduate and graduate students a thorough review of the entire field. The mass of data related to aging is summarized into fifteen focused chapters, each dealing with some particular aspect of the problem. His prior two editions have also served admirably as a reference text for clinicians and scientists. This new edition captures the extraordinary recent advances in our knowledge of the ultimate and proximal mechanisms underlying the phenomenon of aging.

Book Description
The second edition of this well-received text is at least 50% larger than its predecessor, with most of the additional pages devoted to clinical diagnosis and treatment of a wide range of common neuro-otologic disorders. Algorithms and tables guide the practitioner confronted with a patient complaining of dizziness or related symptoms. Newer tests are discussed, and the chapter on the evaluation of hearing has been significantly expanded. The highly praised sections on basic neurophysiology reflect the latest research. This edition features 87 new illustrations including tables, diagnostic charts, and MRI and CT scans.
