Neutron Spin Echo in Polymer Systems
Neutron spin echo spectroscopy (NSE) provides the unique opportunity to unravel the molecular dynamics of polymer chains in space and time, covering most of the relevant length and time scales. This article reviews in a comprehensive form recent advances in the application of NSE to problems in polymer physics and describes in terms of examples expected future trends. The review commences with a description of NSE covering both the generic longitudinal field set-up as well as the resonance technique. Then, NSE results for homopolymers chains are presented, covering all length scales from the very local secondary J3-relaxation to large scale reptation. This overview is the core of the review. Thereafter the dynamics of more complex systems is addressed. Starting from polymer blends, diblock copolymers, gels, micelles, stars and dendrirners, rubbery electrolytes and biological macromolecules are discussed. Wherever possible the review relates the NSE findings to the results of other techniques, in particular emphasizing computer simulations.

Neurotransmitter Interactions and Cognitive Function
Cognitive function involves the participation of many different neurotransmitter systems in a variety of brain areas. The centerpiece of investigation regarding cognitive function has classically been the cholinergic system, but it has become increasingly clear that other transmitter systems interact with cholinergic systems to provide the neural basis for cognitive function. This book brings together cutting edge research to determine how the transmitter interactions form the mechanistic bases for attention, learning and memory. This research on transmitter interactions not only provides a more accurate, though complex, picture of how the brain works to provide cognitive function, it also provides important new levels of understanding about the mechanisms of cognitive dysfunction and novel avenues for therapeutic treatment. The researchers who contributed to this volume both reviewed the latest findings but also point to the directions of advancement of the field of neurotransmitter interactions and cognitive function.

Neurology Oral Boards Review : A Concise and Systematic Approach to Clinical Practice
Rapid recall of vast amounts of factual material is the key to success in both the Neurology Oral Board examination and in everyday patient care. In Neurology Oral Boards Review: A Concise and Systematic Approach to Clinical Practice, Eroboghene E. Ubogu offers a comprehensive review of relevant topics and examination strategies needed to pass the American Board of Psychiatry and Neurology (ABPN) Part II (Oral) exam, complete with up-to-date, evidence-based guidelines on diagnosis and management in clinical neurology. The author has written the book specifically to satisfy the requirements of the ABPN, with clinical case vignettes designed to allow the examinee to localize the plausible disease process, to indicate which investigations may help in establishing a diagnosis, to deduce treatment plans, and to make a prognosis, including patient and family counseling. The emergency cases test the ability to think critically when faced with a neurological emergency, putting a premium on resuscitation, patient safety, and rapid high-yield investigations. The general neurology cases reflect the breadth of disorders experienced in hospital and outpatient settings. The author also provides a detailed description of the oral ABPN examination and suggests a study regimen that takes into account the difficulties of allotting time to prepare while in post-residency training or practice.
Neuroimmunology of Sleep
Neuroimmunology of Sleep provides an introduction to the interphase between sleep and neuroimmunology. Written both from basic and clinical perspectives, the volume contains useful information to many biomedical professionals and students of human biology.
Neurodevelopmental Disorders
The book comprises a number of topics related to psychosocial and motor development and is exemplary with regard to its comprehensiveness, as reviews of the topics presented are generally not available in a single publication. It starts with a timely and critical discussion of the genetics of attention deficit hyperactivity disorder by Dr. Buitelaar in which prospects and challenges of this approach are outlined. The next chapter by Drs. Nicolson and Fawcett deals with dyslexia and its relationship to cerebellar function providing a framework that can explain motor, speed, and phonological deficits in a unified approach. Diagnostic and treatment aspects of speech development disorders are the focus of Dr. Zorowka’s contribution in which, among other issues, the necessity of mul- professional cooperation is stressed. Dr. Sigmundsson then focuses on disorders of motor development. 6-10 % of children have motor competence well below the norm, which often persist.
Neuroblastoma
Neuroblastoma is a medical enigma. As a childhood neoplasm arising from neural crest cells, it is characterized by diverse clinical behaviors ranging from spontaneous remission to rapid tumor progression and death. Although clinical outcome can be predicted to a large extent by the stage of disease and the age at diagnosis, an in-depth understanding of its clinico-pathological behavior, now greatly aided by sophisticated molecular genetic profiling, will improve diagnostic precision and refine risk-based therapies. Comprehensive international efforts have advanced our understanding of tumor biology and improved the clinical management of children with neuroblastoma. This book reviews our current understanding of the genes and biological pathways that contribute to neuroblastoma pathogenesis, modern risk-based treatment approaches for these patients, and recent advances in biologically based therapy. It provides a concise up-to-date reference for practitioners, students, and researchers.
Neurobiology of Human Values
Man has been pondering for centuries over the basis of his own ethical and aesthetic values. Until recent times, such issues were primarily fed by the thinking of philosophers, moralists and theologists, or by the findings of historians or sociologists relating to universality or variations in these values within various populations. Science has avoided this field of investigation within the confines of philosophy. Beyond the temptation to stay away from the field of knowledge science may also have felt itself unconcerned by the study of human values for a simple heuristic reason, namely the lack of tools allowing objective study. For the same reason, researchers tended to avoid the study of feelings or consciousness until, over the past two decades, this became a focus of interest for many neuroscientists
Neurobiology : Methods and protocols
Serves as a guide for students in the field of neurobiology, and be a bridge between basic science researchers, doctors, and surgeons in clinical practice. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
Neuroanatomy for the Neuroscientist
Neurology, more than any other system of medicine, is rooted in the firm knowledge of basic science material (i.e., the anatomy, physiology, and pathology of the nervous system). This material enables students to readily arrive at diagnoses and to apply their knowledge at solving problems in clinical situations. Neuroanatomy for the Neuroscientist gives neuroscientists the tools to teach this material at levels appropriate for students at several levels of study, including undergraduate, graduate, dental, and medical school. The text also provides an updated approach to lesion localization in neurology, utilizing the techniques of computerized axial tomography (CT scanning), magnetic resonance imaging (MRI), and magnetic resonance angiography (MRA). Multiple illustrations demonstrating the value of these techniques in clinical neurology and neuroanatomical localization has been provided.
Neuroanatomical Tract-Tracing : Molecules, Neurons, and Systems
"The content of the book also serves to emphasize that neuroanatomy is, perhaps more than ever, a thriving and important part of the neurosciences...Most contributions have in common the combination of modern tract-tracing methods with other means of characterizing neural tissue, and thus the book also serves to highlight the gradual disappearance of borders between traditional neuroanatomy and other approaches to the study of the nervous system...this book should continue to be a useful source of information, and deserves to be available in all laboratories applying or considering to apply neuroanatomical methods."
Neuroactive Steroids in Brain Function, Behavior and Neuropsychiatric Disorders : Novel Strategies for Research and Treatment
Over the past few decades the involvement of neurosteroids in brain function and mental health has attracted much interest, not only from a neuroscience perspective, but also from clinical and therapeutic aspects. In recent years, much of the research has focused on the multifunctional position of neurosteroids in the nervous system. The areas that have been explored, in particular, are the cellular and molecular mechanisms involved in the activity of neurosteroids in the brain, the role of neurosteroids in brain development, neurodegeneration and neuroplasticity, and their pharmacological properties. The large increase in the number of publications highlights this amplified interest in neurosteroids. Over the last 7 years at least 400 papers have been published describing the putative role of neurosteroids in the modulation of basic brain function and in the etiology and treatment of psychiatric and neurological disorders.
Neuroacanthocytosis Syndromes
Neuroacanthocytosis Syndromes is the first comprehensive review of a field that has not yet received the attention it deserves. Affecting the brain as well as the circulating red cells, these multi-system disorders in the past had often been mistaken for Huntington's disease. Recent breakthroughs have now identified the molecular basis of several of these. This volume grew out of the first international scientific meeting ever devoted to neuroacanthocytosis and provides in-depth information about the state of the art. Its thirty chapters were written by the leading authorities in the field to cover the clinical as well as the basic science perspective, including not only molecular genetics but also experimental pharmacology and cell membrane biology, among others. The book vehemently poses the question of how the membrane deformation of circulating red blood cells relates to degeneration of nerve cells in the brain, the basal ganglia, in particular. It provides a wealth of data that will help to solve an intriguing puzzle and ease the suffering of those affected by one of the neuroacanthocytosis syndromes.
Neural networks and deep learning
Covers both classical and modern models in deep learning. The primary focus is on the theory and algorithms of deep learning. The theory and algorithms of neural networks are particularly important for understanding important concepts, so that one can understand the important design concepts of neural architectures in different applications. Why do neural networks work? When do they work better than off-the-shelf machine-learning models? When is depth useful? Why is training neural networks so hard? What are the pitfalls? The book is also rich in discussing different applications in order to give the practitioner a flavor of how neural architectures are designed for different types of problems.
