The spinal cord is comprised of four types of neurons: motor neurons, pre-ganglionic neurons, ascending projection neurons, and spinal interneurons. Interneurons are neurons that process information within local circuits, and have an incredible ability for neuroplasticity, whether due to persistent activity, neural injury, or in response to disease. Although, by definition, their axons are restricted to the same structure as the soma (in this case the spinal cord), spinal interneurons are capable of sprouting and rewiring entire neural circuits, and contribute to some restoration of disrupted neural communication after injury to the spinal cord (i.e., “bypassing the lesion site). Spinal Interneurons provides a focused overview of how scientists classify interneurons in general, the techniques used to identify subsets of interneurons, their roles in specific neural circuits, and the scientific evidence for their neuroplasticity. Understanding the capacity for neuroplasticity and identity of specific spinal interneurons that are optimal for recovery, may help determine cellular candidates for developing therapies. Spinal Interneurons provides neuroscientists, clinicians, and trainees a reference book exclusively concentrating on spinal interneurons, the techniques and experiments employed to identify and study these cells as part of normal and compromised neural circuits, and highlights the therapeutic potential of these cells by presenting the relevant pre-clinical and clinical work to date. People in industry will also benefit from this book, which compiles the latest in therapeutic strategies for targeting spinal interneurons, what considerations there are for the development and use of treatments, and how such treatments can not only be translated to the clinic, but how existing treatments should be appropriately reverse-translated to the bench. Comprehensive overview of techniques used to identify, characterize, and classify spinal interneurons and their role in neural circuits Description of the role that spinal interneurons play in mediating plasticity after compromise to spinal neural networks In-depth discussion of therapeutic potential of spinal interneurons for spinal cord injury and/or disease
Edited and authored by a wealth of international experts in neuroscience and related disciplines, this key new resource aims to offer medical students and graduate researchers around the world a comprehensive introduction and overview of modern neuroscience. Neuroscience research is certain to prove a vital element in combating mental illness in its various incarnations, a strategic battleground in the future of medicine, as the prevalence of mental disorders is becoming better understood each year. Hundreds of millions of people worldwide are affected by mental, behavioral, neurological and substance use disorders. The World Health Organization estimated in 2002 that 154 million people globally suffer from depression and 25 million people from schizophrenia; 91 million people are affected by alcohol use disorders and 15 million by drug use disorders. A more recent WHO report shows that 50 million people suffer from epilepsy and 24 million from Alzheimer’s and other dementias. Because neuroscience takes the etiology of disease—the complex interplay between biological, psychological, and sociocultural factors—as its object of inquiry, it is increasingly valuable in understanding an array of medical conditions. A recent report by the United States’ Surgeon General cites several such diseases: schizophrenia, bipolar disorder, early-onset depression, autism, attention deficit/ hyperactivity disorder, anorexia nervosa, and panic disorder, among many others. Not only is this volume a boon to those wishing to understand the future of neuroscience, it also aims to encourage the initiation of neuroscience programs in developing countries, featuring as it does an appendix full of advice on how to develop such programs. With broad coverage of both basic science and clinical issues, comprising around 150 chapters from a diversity of international authors and including complementary video components, Neuroscience in the 21st Century in its second edition serves as a comprehensive resource to students and researchers alike.
Jasper's Basic Mechanisms, Fourth Edition, is the newest most ambitious and now clinically relevant publishing project to build on the four-decade legacy of the Jasper's series. In keeping with the original goal of searching for "a better understanding of the epilepsies and rational methods of prevention and treatment.", the book represents an encyclopedic compendium neurobiological mechanisms of seizures, epileptogenesis, epilepsy genetics and comordid conditions. Of practical importance to the clinician, and new to this edition are disease mechanisms of genetic epilepsies and therapeutic approaches, ranging from novel antiepileptic drug targets to cell and gene therapies.
This volume focuses on the interplay of mind and motion-the bidirectional link between thought and action. In particular, it investigates the implications that this coupling has for decision making. How do we anticipate the consequences of choices and how is the brain able to represent these choice options and their potential consequences? How are different options evaluated and how is a preferred option selected and implemented? This volume addresses these questions not only through an extensive body of knowledge consisting of individual chapters by international experts, but also through integrative group reports that pave a runway into the future. The understanding of how people make decisions is of common interest to experts working in fields such as psychology, economics, movement science, cognitive neuroscience, neuroinformatics, robotics, and sport science. So far, however, it has mainly been advanced in isolation within distinct research disciplines; in contrast, this book results from a deliberate assembly of multidisciplinary teams. It offers intense, focused, and genuine interdisciplinary perspective. It conveys state-of-the-art and outlines future research directions on the hot topic of Mind and Motion (or embodied cognition). It includes contributions from psychologists, neuroscientists, movement scientists, economists, and others.
Spinal Muscular Atrophy: Disease Mechanisms and Therapy provides the latest information on a condition that is characterized by motoneuron loss and muscle atrophy, and is the leading genetic cause of infant mortality. Since the identification of the gene responsible for SMA in 1995, there have been important advances in the basic understanding of disease mechanisms, and in therapeutic development. This book provides a comprehensive accounting of recent advances in basic and clinical research that covers SMA clinical features and standards of care, multifaceted aspects of SMN protein functions and SMA disease pathology, various animal models, and biomarkers, as well as current therapeutic development. This title is ideal for graduate students/postdocs and principal investigators who are already in the SMA field and need to keep updated on recent findings and approaches, and for those who are new to, or would like to join, the field. Likewise, users will find an excellent source of reading for biotech/pharma scientists, clinical researchers, and practitioners, regulators, and patients and their advocacy organizations. Furthermore, this book is a handy reference for researchers and clinicians who may want to apply the research strategies and therapeutic approaches in SMA to other rare diseases.

In this, the post-genomic age, our knowledge of biological systems continues to expand and progress. As the research becomes more focused, so too does the data. Genomic research progresses to proteomics and brings us to a deeper understanding of the behavior and function of protein clusters. And now proteomics gives way to neuroproteomics as we beg
Studies of human movement have proliferated in recent years, and there have been many studies of spinal pathways in humans, their role in movement, and their dysfunction in neurological disorders. This comprehensive reference surveys the literature related to the control of spinal cord circuits in human subjects, showing how they can be studied, their role in normal movement, and how they malfunction in disease states. Chapters are highly illustrated and consistently organised, reviewing, for each pathway, the experimental background, methodology, organisation and control, role during motor tasks, and changes in patients with CNS lesions. Each chapter concludes with a helpful resume that can be used independently of the main text to provide practical guidance for clinical studies. This will be essential reading for research workers and clinicians involved in the study, treatment and rehabilitation of movement disorders.
Even though spinal cord research has expanded enormously during the past decades, we still lack a precise understanding of how spinal interneuron networks perfectly integrate sensory feedback with motor control, and how these neuron circuits give rise to specific functions. The present study thus has three basic aims: (1) to investigate propriospinal interneurons connecting rostral and caudal lumbar spinal cord in the rat; (2) to investigate input properties of identified spinal interneurons interposed in different pathways; (3) to investigate cholinergic terminals in the ventral horn of adult rat and cat. There was no evidence to support the presence of vesicular glutamate transporters in motoneuron axon terminals of either species. In addition, there was no obvious relationship between motoneuron terminals and R2 subunit of the AMPA receptor (GluR2). However, a population of cholinergic terminals in lamina VII, which did not originate from motoneurons, was found to be immunoreactive for VGLUT2 and formed appositions with GluR2 subunits. These terminals were smaller than motoneuron terminals and, unlike them, formed no relationship with Renshaw cells. The evidence suggests that glutamate does not act as a cotransmitter with acetylcholine at central synapses of motoneurons in the adult cat and rat. However, glutamate is present in a population of cholinergic terminals which probably originate from interneurons where its action is via an AMPA receptor. In conclusion, the present studies add to the understanding of the organization of neuronal networks involved in sensorimotor integration. Propriospinal interneurons located within the lumbar segments have extensive intra-segmental projections to motor nuclei. First order interneurons interposed in reflex pathways and descending pathways receive a significantly different pattern of inputs. A similar proportion of monosynaptic excitatory input from primary afferents has been found in both excitatory and inhibitory interneurons and these two types of cells are subject to presynaptic inhibitory control of this input.
The neurology of sex and bladder disorders requires specialized knowledge and represents a challenge for clinical neurologists focused on the neurological condition. Sex and bladder disorders are often related to more general neurological disorders like Parkinson’s disease and multiple sclerosis, and often the sex and bladder disorders are passed to specialists in urology. Neurology of Sexual and Bladder Disorders: Handbook of Clinical Neurology is a focused, yet comprehensive overview that provides complete tutorial reference to the science, diagnosis and treatment of sex and bladder disorders from a neurologic perspective. Comprehensive coverage of the neurology of sex and bladder disorders Details the latest techniques for the study, diagnosis and treatment of sex and bladder dysfunction from a neurological perspective A focused reference for clinical practitioners and neurology research communities
Advances in itch research have elucidated differences between itch and pain but have also blurred the distinction between them. There is a long debate about how somatic sensations including touch, pain, itch, and temperature sensitivity are encoded by the nervous system. Research suggests that each sensory modality is processed along a fixed, direct-line communication system from the skin to the brain. Itch: Mechanisms and Treatment presents a timely update on all aspects of itch research and the clinical treatment of itch that accompanies many dermatological conditions including psoriasis, neuropathic itch, cutaneous t-cells lymphomas, and systemic diseases such as kidney and liver disease and cancer. Composed of contributions from distinguished researchers around the world, the book explores topics such as: Neuropathic itch Peripheral neuronal mechanism of itch The role of PAR-2 in neuroimmune communication and itch Mrgprs as itch receptors The role of interleukin-31 and oncostatin M in itch and neuroimmune communication Spinal coding of itch and pain Spinal microcircuits and the regulation of itch Examining new findings on cellular and molecular mechanisms, the book is a compendium of the most current research on itch, its prevalence in society, and the problems associated with treatment.
