Significant progress has been made in the development of neural prostheses to restore human functions and improve the quality of human life. Biomedical engineers and neuroscientists around the world are working to improve design and performance of existing devices and to develop novel devices for artificial vision, artificial limbs, and brain–machine interfaces. This book, Implantable Neural Prostheses 1: Devices and Applications,ispart one of a two-book series and describes state-of-the-art advances in techniques associated with implantable neural prosthetic devices and their applications. Devices covered include sensory prosthetic devices, such as visual implants, cochlear implants, auditory midbrain implants, and spinal cord stimulators. Motor prosthetic devices, such as deep brain stimulators, Bion microstimu- tors, the brain control and sensing interface, and cardiac electro-stimulation devices are also included. Progress in magnetic stimulation that may offer a non-invasive approach to prosthetic devices is introduced. Regulatory approval of implantable medical devices in the United States and Europe is also discussed.

Neural prostheses have been used for centuries as structural replacements, in particular for injuries to the cranium. And today, neural prostheses are designed to restore a broad range of nervous system functions previously lost due to trauma or disease. While their complexity may vary from nerve conduits to prosthetic brain implants, neural devices have improved the lives of patients and broadened the scope of disabilities that can be treated. Neural Prostheses is the first comprehensive book to look at the history and recent, state-of-the-art developments of neural prostheses. Dr. Maciunas has gathered the country's leading experts in structural and functional protheses development to provide a look at the history, current use and the future of prostheses in the areas of: Spinal instrumentation as implanted neural prostheses Cranial reconstruction Angioplasty and stenting The use of indwelling of radioisotopes Chemodes Slow-release polymers for chemotherapy Cell transplantation for movement disorders Gene therapy for the treatment of CNS disease Microelectrode prostheses Cochlear implants -The use of robotics (Distributed by Thieme for the American Association of Neurological Surgeons)

WINNER 2009 CHOICE AWARD OUTSTANDING ACADEMIC TITLE! Nanotechnology is no longer a subdiscipline of chemistry, engineering, or any other field. It represents the convergence of many fields, and therefore demands a new paradigm for teaching. This textbook is for the next generation of nanotechnologists. It surveys the field’s broad landscape, exploring the physical basics such as nanorheology, nanofluidics, and nanomechanics as well as industrial concerns such as manufacturing, reliability, and safety. The authors then explore the vast range of nanomaterials and systematically outline devices and applications in various industrial sectors. This color text is an ideal companion to Introduction to Nanoscience by the same group of esteemed authors. Both titles are also available as the single volume Introduction to Nanoscience and Nanotechnology Qualifying instructors who purchase either of these volumes (or the combined set) are given online access to a wealth of instructional materials. These include detailed lecture notes, review summaries, slides, exercises, and more. The authors provide enough material for both one- and two-semester courses.

Changes in the statistical properties of neural signals recorded at the brain machine interface (BMI) pose significant challenges for accurate long-term control of prostheses interfaced directly with the brain by continuously altering the relationship between neural responses and desired action. In this thesis, we develop and test an adaptive decoding algorithm that can recover from changes in the statistical properties of neural signals within minutes. The adaptive decoding algorithm uses a Kalman filter as part of a dual-filter design to continuously optimize the relationship between the observed neural responses and the desired action of the prosthesis. Performance of the algorithm was evaluated by simulating the encoding of arm movement by neurons in the primary motor cortex under stationary conditions as well as nonstationary conditions depicting loss and/or replacement of neurons in the population. The time taken for the system to fully recover (3-12 minutes) was faster than other adaptive systems (Rotermund et al 2006) and resulted in errors that were well matched to the initial system performance. The algorithm adapts to the local properties of the stimulus and is able to decode movements with high accuracy outside the trained movement space. This implementation lends itself favorably toward a portable, robust long-term decoding approach at the brain machine interface capable of providing accurate real-time decoding of neural signals over periods of weeks to months without outside intervention.

Neural prosthetics are systems or devices implanted in or connected to the brain that influence the input and output of information. They modulate, bypass, supplement, or replace regions of the brain and its connections to parts of the body that are damaged, dysfunctional, or lost, whether from congenital conditions, brain injury, limb loss, or neurodegenerative disease. Neural prosthetics can restore sensory, motor, and cognitive functions in people with these conditions and enable them to regain functional independence and improve their quality of life. This book explores the neuroscientific and philosophical implications of neural prosthetics. Neuroscientific discussion focuses on how neural prosthetics can restore brain and bodily functions to varying degrees, looking at auditory and visual prosthetics, deep brain and responsive neurostimulation, brain-computer interfaces, brain-to-brain interfaces, and memory prosthetics. Philosophical discussion then considers the degree to which people with these prosthetics can benefit from or be harmed by them. Finally, it explores how these devices and systems can lead to a better understanding of the brain-mind relation, mental causation, and agency. This is an essential volume for anyone invested in the current and future directions of neural prosthetics, including neuroscientists, neurologists, neurosurgeons, neural engineers, psychologists, and psychiatrists, as well as philosophers, bioethicists, and legal theorists.

Cochlear implants are currently the standard treatment for profound sensorineural hearing loss. In the last decade, advances in auditory science and technology have not only greatly expanded the utility of electric stimulation to other parts of the auditory nervous system in addition to the cochlea, but have also demonstrated drastic changes in the brain in responses to electric stimulation, including changes in language development and music perception. Volume 20 of SHAR focused on basic science and technology underlying the cochlear implant. However, due to the newness of the ideas and technology, the volume did not cover any emerging applications such as bilateral cochlear implants, combined acoustic-electric stimulation, and other types of auditory prostheses, nor did it review brain plasticity in responses to electric stimulation and its perceptual and language consequences. This proposed volume takes off from Volume 20, and expands the examination of implants into new and highly exciting areas. This edited book starts with an overview and introduction by Dr. Fan-Gang Zeng. Chapters 2-9 cover technological development and the advances in treating the full spectrum of ear disorders in the last ten years. Chapters 10-15 discuss brain responses to electric stimulation and their perceptual impact. This volume is particularly exciting because there have been quantum leap from the traditional technology discussed in Volume 20. Thus, this volume is timely and will be of real importance to the SHAR audience.
