This volume provides up-to-date information concerning new applications of brain imaging to the study of Parkinson’s disease (PD). The chapters, written by experts in this field, focus on the various imaging methodologies that have recently been used to study the natural history of the disease with emphasis on each of the distinctive clinical features that characterize the disorder (e.g., bradykinesia, rigidity, tremor and gait disturbance). Individual chapters also address the role of imaging in differential diagnosis, and in the evaluation of cognitive dysfunction/dementia in parkinsonian patients. Considerable emphasis is placed on potential applications of neuroimaging in clinical trials to assess new pharmacologic and surgical treatment strategies for PD, including deep brain stimulation (DBS), cell transplantation, and gene therapy. In-depth discussion is provided on advanced imaging applications, including rest-state and activation fMRI, volumetric MR, PET assessment of dopaminergic and cholinergic neurotransmission, and echosonography. Additional topics cover recent developments in the use of brain imaging to assess disease mechanisms including neuroinflammation, protein aggregation, and disordered brain network organization in PD.

The study of brain aging has been revolutionized through advances in molecular neuroscience, cognitive neuroscience, and brain imaging. The application of new concepts and techniques has permitted investigators to explore the changes in structure, function, and biochemistry in living humans in order to unravel mechanisms that underlie both age-related cognitive decline and preservation of cognition into old age. This book reviews both the basic science and clinical applications of brain imaging in the study of brain aging. Topics reviewed include technical issues associated with imaging studies in older brains, pathology of brain aging, structural changes in the aging brain, changes in dopamine function, and mechanisms of brain reserve and plasticity. The use of genetics in combination with brain imaging and the use of animal models are also explored. Clinical applications include the diagnosis and prediction of cognitive decline using a variety of different imaging approaches as well as a detailed description of amyloid imaging using PET scanning. Other topics include functional MRI studies in aging, the use of imaging in therapeutic monitoring and drug development, and the role of large-scale databases. The volume contains information both for those involved in brain imaging research and for those new to the field who are in need of a systematic overview.

This new edition covers advances in understanding immunological and inflammatory responses in the nervous system, research driven by the potential to use knowledge of the molecules and mechanisms involved to intervene in, and arrest, neurodegenerative disease processes. This book covers developmental aspects of immune/inflammatory responses in the central nervous system (CNS), basic aspects of glial function, as well as inflammatory mediators, their mechanisms of action, clinical importance, and sites of infection. There is also coverage of the major diseases of the CNS, including stroke, brain injury, multiple sclerosis, and Alzheimer's disease. Throughout, the focus is on the underlying basic neuroscience, clinical relevance, and the potential for therapeutic interventions. The book will be useful for improving the diagnosis of neuroimmune diseases and determining therapeutic measures.

This book evaluates the progress of schizophrenia science by summarizing what is known about how patients with the illness differ from healthy people. The tools of meta-analysis are first explained and then employed to make the strength and consistency of these differences explicit. Beginning with the study of symptoms, then moving through the search for objective disease markers, findings on the cognitive functions, structure, physiology, chemistry, and development of the brain, this book is a journey into the enigma of madness and its science. Schizophrenia emerges as an illness that reveals itself most strongly in thought processes, not biology. Schizophrenia is an anomaly at the frontier of mind and brain, and this book points the way to its solution.

The study of conscious experience has seen remarkable strides in the last ten years, reflecting important technological breakthroughs and the enormous efforts of researchers. Although still embroiled in debate, scientists are now beginning to find common ground in their understanding of consciousness, which may pave the way for a unified explanation of how and why we experience and understand the world around us. This book brings the subject to life with a metaphor that has been used to understand consciousness since the time of Aristotle—the mind as theater. Here consciousness is seen as a “stage” on which our sensations, perceptions, thoughts, and feelings play to a vast, silent audience (the immensely complicated inner-workings of the brain's unconscious processes). Behind the scenes, silent context operators shape conscious experience; they include implicit expectations, self systems, and scene setters. Using this framework, the book presents compelling evidence that human consciousness rides on top of biologically ancient mechanisms. In humans it manifests itself in inner speech, imagery, perception, and voluntary control of thought and action. Topics like hypnosis, absorbed states of mind, adaptation to trauma, and the human propensity to project expectations on uncertainty, all fit into the expanded theater metaphor.

This book provides an overview by international authorities, spanning the disciplines of neuroscience, psychology, ophthalmology, optometry, and paediatrics, of normal and pathological infant visual development. It covers the development of retinal receptors; infant sensitivity to detail, colour, contrast, and movement; binocularity, eye movements, and refraction; and cognitive processing. Childrens' visual deficits, including amblyopia and cataract, are covered.

Key thoughts leaders and practitioners in personalized medicine distil its current status, future directions, and recommendation for successful implementation of for brain disorders. This text is a summary of the “science to patient” continuum in and integrative neuroscience. Included are measures of genes using whole genome approaches and SNIPS, as well as BRAINmarkers of direct brain function such as brain imaging, biophysical changes and objective cognitive and behavioral measurements. The chapters provide a review of relevant literature; show the personalized diagnostic and treatment prediction solutions for patient care achieved through integrative neuroscience, providing a practical guide. This book provides a summary of the key translations from laboratory discoveries to patient and reimbursement issues, in personalized medicine.

This book offers a fundamental new theory of motor cortex organization: the rendering of the movement repertoire onto the cortex. The action repertoire of an animal is highly dimensional, whereas the cortical sheet is two-dimensional. Rendering the action space onto the cortex therefore results in a complex pattern, explaining the otherwise inexplicable details of motor cortex organization. This book includes a complete history of motor cortex research from its discovery to the present, a discussion of the major issues in motor cortex research, and an account of recent experiments that led to the book's “action map” view. Though focused on motor cortex, the book includes a range of topics from an explanation of how primates put food in their mouths, to the origins of social behavior such as smiling and laughing, to the mysterious link between movement disorders and autism.

This book provides a review of developments made in the understanding of cellular activation phenomena in striated muscle. Basic physical, mathematical, and physiological principles are covered. The book consistently draws correlations both with cellular and molecular biological information, and their physiological consequences and significance. It is accessible both as a survey of basic concepts and as an authoritative review of recent work in the field. The book succeeds in explaining complex biophysics in such a way that the non-expert reader obtains insights into the molecular mechanisms of muscle activation and their control mechanisms, as well as in providing the expert with the detailed mathematical and experimental evidence.
