Whatever you may say about Professor Samii, his take on neurosurgery cannot be ignored. In this book readers will find pieces that express the philosophy of the most well-known 'Neurosurgical School'. International experts present Professor Samii's teaching and philosophy in dealing with the most difficult neurosurgical pathologies as well as future developments. Basic concepts in neurosurgical sciences, modern surgical techniques and cutting-edge technology are presented in detail.
Speech Production: Models, Phonetic Processes and Techniques brings together researchers from many different disciplines - computer science, dentistry, engineering, linguistics, phonetics, physiology, psychology - all with a special interest in how speech is produced. From the initial neural program to the end acoustic signal, it provides an overview of several dominant models in the speech production literature, as well as up-to-date accounts of persistent theoretical issues in the area. A particular focus is on the evaluation of information gleaned from instrumental investigations of the speech production process, including MRI, PET, ultra-sound, video-imaging, EMA, EPG, X-ray, computer simulation - and many others. The research presented in this volume considers questions such as: the feed-back vs. feed-forward control of speech; the acoustic/auditory vs. articulatory/somato-sensory domains of speech planning; the innateness of human speech; the possible architecture of a speech production model; and the realization of prosodic structure in speech. Leaders in speech research from around the world have contributed their most recent work to this volume.
This book covers stereotactic principles as well as functional stereotaxis, covering the history and uses of the techniques, treatments for specific conditions, and future developments. Includes a DVD demonstrating surgical procedures.
Einige tausend Menschen sind weltweit an einer Leitungsunterbrechung des Hörnerven im Hirnstamm erkrankt. Dies führt in vielen Fällen zum Verlust des Hörens, d.h. zur Taubheit. Inzwischen ist es möglich, im Rahmen einer Gehirnoperation alltagsrelevante Teile des Hörvermögens wieder herzustellen. Dies geschieht durch Elektroden, die im Mittelhirn eingesetzt werden und die mit einem implantierten Mikroprozessor verbunden sind. Im vorliegenden Buch werden hierzu einige grundsätzliche Überlegungen, Laborstudien, sowie erstmalig klinische Ergebnisse dargestellt. Diese mikroskopische Implantation im akkustischen Teil des Gehirns ist das erfolgreichste Beispiel der neuroprothetischen Wiederherstellung eines zerstörten Sinnesorganes. Die vorgestellte Studie wurde im Rahmen einer Habilitationsarbeit angefertigt. Förderung erfolgte (2001) durch Mittel der Deutschen Forschungsgemeinschaft (DFG), der Max-Kade Stiftung, sowie durch ein Reisestipendium der Weltgesundheitsorganisation (WHO).

Mathematical models are being increasingly used to estimate the concentrations of a wide range of substances in the environment for a variety of reasons, including government control and legislation, and risk and hazard estimation. Exposure assessment has to be performed for many types of substances, including pesticides, industrial chemicals, pollutants, accidental discharges, etc. The interpretation of the results of model equations should always bear in mind the purpose for which the model used was built in the first place. Further, models are always an abstraction of reality, requiring simplifying assumptions to keep the models within the restraints posed by computer performance and/or scientific knowledge. The present book treats the theme of modelling chemical exposure and risk in terms of four main topics: model characteristics, applications, comparison of estimated with measured concentrations, and modelling credibility.
“Practical Handbook of Neurosurgery” invites readers to take part in a journey through the vast field of neurosurgery, in the company of internationally renowned experts. At a time when the discipline is experiencing a (detrimental) tendency to segment into various subfields and scatter in the process, it can be worthwhile to collect a number of practical lessons gleaned from experienced and leading neurosurgeons. The book also aims to present numerous important figures in the neurosurgical community, with a brief overview of the vitae and main contributions for each. We must confess that we were sad that some of the most active members were unable to participate, likely due to time cons...
This text provides a comprehensive and contemporary overview of surgical approaches to lesions of the posterior fossa. It will serve as a resource for neurosurgeons and otologists who treat patients with tumors and vascular diseases of the posterior fossa. It provides a concise review of surgical strategies that address the most important pathologies affecting the posterior fossa. It is richly illustrated with photographs and illustrations of the surgical strategies covered. All chapters are written by experts with world-wide recognition for their contributions in their respective subspecialty. Skull Base Surgery of the Posterior Fossa will be of great utility to Neurosurgeons, Otolaryngologists, and Radiation Therapists with an interest in diseases that affect the posterior fossa, as well as Senior Residents in Neurosurgery and Otolaryngology, and Fellows of Skull Base Surgery and Otology.
This book demonstrates an integrated perspective of trends and challenges in sustainable river science and management, as presented by experts in the fields that form its foundations - ecology, economy and sociology. Their contributions integrate current knowledge of the structure, functioning and management of ‘living rivers’. Also included are data and experiences concerning the rivers Allier, Meuse, Rhine, Sava and Tagliamento in Europe and the Illinois River in the USA.
