The Novartis Foundation Series is a popular collection of the proceedings from Novartis Foundation Symposia, in which groups of leading scientists from a range of topics across biology, chemistry and medicine assembled to present papers and discuss results. The Novartis Foundation, originally known as the Ciba Foundation, is well known to scientists and clinicians around the world.
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.
The membranous labyrinth lies enclosed in the very hard petrous part of the temporal bone and, as the name implies, its structure is extremely complex. This may explain why our knowledge of this organ and the vestibular sensory regions within it, is not yet satisfactory. In recent years the rapid development of space research has provided a power ful stimulus to our interest in the vestibular apparatus. This has found expression in annual symposia, in which the role of the vestibular organs in the exploration of space is discussed. However, little is known as yet about the influence upon the equilibrial apparatus, during space flight, of weightlessness and other related conditions. The inner ear has also acquired increased significance from an otosurgical point of view. Operations are today performed in regions previously inaccessible to surgery. This requires exact knowledge of anatomical details and of relations between the different structures in the inner ear.

THE BEST-SELLING BOOK ON THE TOPIC! The third edition of Balance Function Assessment and Management, the leading textbook on the subject, continues to comprehensively address the assessment and treatment of balance system impairments through contributions from top experts in the areas of dizziness and vertigo. Designed for use in graduate audiology programs and by practicing audiologists, this is also a valuable text for those in the fields of physical therapy, otolaryngology, and neurology. New to the Third Edition: * Reorganized with the expertise of four additional Editors: Kamran Barin, PhD, Robert F. Burkard, PhD, Kristen Janky, AuD, PhD, and Devin L. McCaslin, PhD * Three new chapters: An Historical Perspective of the Perception of Vertigo, Dizziness, and Vestibular Medicine (Zalewski); Vestibular Balance Therapy for Children (Christy); and Challenging Cases (Shepard) * All existing chapters have been revised and updated * An effort has been made to make the text more concise * Three new helpful appendices covering the pathophysiology behind dizziness, coding and billing, and an overview of Interprofessional Education (IPE) and Interprofessional Practice (IPP) Disclaimer: Please note that ancillary content (such as documents, audio, and video, etc.) may not be included as published in the original print version of this book.
No detailed description available for "Differential Diagnosis of Vertigo / Die Differentialdiagnose des Schwindels /Diagnostico diferencial de las enfermedades con mareo / Le diagnostic différential du vertige".
The focus of this volume differs from what is suggested by the series title, for it is on muscle contraction and movement rather than on behavior. The lone overnight flight of a ruby-throated hummingbird across the Gulf of Mexico is a migratory behavior mediated through an incredibly lengthy, repetitive series of wing move ments, each movement being produced by a complex sequence of muscle contrac tions. It is significant that these same movements may be used to mediate other behaviors, and that these same muscle contractions, in different sequence, may be used to produce other movements. The immense journey of white-bearded gnus across the Serengeti plains to suitable calving grounds is likewise a migratory behavior mediated through rather more varied, yet repetitive, limb movements, each produced by a complex sequence of muscle contractions. Again, these same movements may be used to mediate other behaviors, and again, the details of each limb movement may be varied through variations in the strength and the sequence of muscle contractions. A laboratory rat may learn to perform an escape behavior in a shuttle box, bringing its performance to a high level of efficiency by modifying its movement on successive trials. After intraperitoneal injection of pentobarbital sodium in an amount sufficient to render the animal severely incoordinated, the escape behavior is still performed, albeit through a different sequence of move ments, even to "rolling" out of the compartment in response to the warning signal.
