Book Description
Traumatic brain injury (TBI) remains a significant source of death and permanent disability, contributing to nearly one-third of all injury related deaths in the United States and exacting a profound personal and economic toll. Despite the increased resources that have recently been brought to bear to improve our understanding of TBI, the developme

Book Description
In two freestanding volumes, the Textbook of Neural Repair and Rehabilitation provides comprehensive coverage of the science and practice of neurological rehabilitation. Revised throughout, bringing the book fully up to date, this volume, Neural Repair and Plasticity, covers the basic sciences relevant to recovery of function following injury to the nervous system, reviewing anatomical and physiological plasticity in the normal central nervous system, mechanisms of neuronal death, axonal regeneration, stem cell biology, and research strategies targeted at axon regeneration and neuron replacement. New chapters have been added covering pathophysiology and plasticity in cerebral palsy, stem cell therapies for brain disorders and neurotrophin repair of spinal cord damage, along with numerous others. Edited and written by leading international authorities, it is an essential resource for neuroscientists and provides a foundation for the work of clinical rehabilitation professionals.

Book Description
This book provides current information about the three areas mentioned in the title: Neuronal Migration and Development, Degenerative Brain Diseases, and Neural Plasticity and Regeneration. The chapters about brain development examine the cellular and molecular mechanisms by which neurons are generated from the ventricular zone in the forebrain and migrate to their destinations in the cerebral cortext. This description of cortical development also includes a discussions of the Cajal-Retzius cell. Another chapter provides insight about the development of another forebrain region, the hypothalamus. The remaining chapters of this section examine the clinical relevance of brain development in certain disease states in humans: neural tube defects and the normal and abnormal development of human electroencephalographic recordings during the first year of age.The second section on degenerative disorders of the brain begins wtih details about the dopaminergic neurons in the substantia niger and their loss in Parkinson's disease. Two subsequent chapters describe changes in brain aging, including changes in the numbers of myelinated axons. Other chapters in this section describe important cellular and molecular changes found in Alzheimer's disease and human epilepsy. Together, these chapters summarize much of our current knowledge about the major molecular and cellular changes found in several degenerative diseases of the brain.The last section addresses the issues of brain plasticity and regeneration in the adult brain and begins with a chapter on how the brain's own stem cells provide newly generated neurons to the hippocampal dentate gyrus and how these neurons become integrated into neural circuitry. The following two chapters examine some of the neuroplastic changes that take place in motor and sensory cortices of awake behaving primates. The concluding two chapters address the issue of regeneration in the injured spinal cord and the factors that may contribute to its success.

Book Description
Degeneration and Regeneration in the Nervous System brings together an international team of contributors to produce a series of critical reviews appraising key papers in the field. The pace of research on brain and spinal cord injury quickened considerably in the last ten years and there is much that is new and important that is covered in this book. However, there is still a long way to go before our knowledge will explain fully why the central nervous system has such a limited capacity for regeneration, and before experimental solutions can be applied to the patient. With emphasis on actual and therapeutic importance of the work reviewed, Degeneration and Regeneration in the Nervous System is a useful overview for graduate students, their teachers and researchers working in this field.

Book Description
A compilation of innovative findings and new directions in neurological recovery After decades of focusing on how to alleviate and prevent recurrence of acute CNS injuries, the emphasis has finally shifted towards repairing such devastating events and rehabilitation. This development has been made possible by substantial progress in understanding the scientific underpinnings of recovery as well as by novel diagnostic tools, and most importantly, by emerging therapies awaiting clinical trials. In this publication, several international experts introduce novel areas of neurological reorganization and repair following CNS damage. Principles and methods to monitor and augment neuroplasticity are explored in depth and supplemented by a critical appraisal of neurological repair mechanisms and possibilities to curtail disability using computer or robotic interfaces. Rather than providing a textbook approach of CNS restoration, the editors selected topics where progress is most imminent in this labyrinthine domain of medicine. Moreover, the varied background and origins of the contributors lend this book a truly global perspective on the current state of affairs in neurological recovery.

Book Description
Central nervous system trauma, which encompasses stroke, subarachnoid hemorrhage, head injury, and spinal cord injury, is a leading cause of death in developed countries. In the search for underlying mechanisms, membrane involvement has been the common link. This fourth volume in the Membrane-Linked Diseases series is therefore dedicated to research on CNS trauma. Focusing on the mechanism of membrane damage, Central Nervous System Trauma: Research Techniques presents a variety of experimental techniques to study the mechanism of CNS trauma. Animal and tissue culture models provide the bulk of the research findings in this area. Possible pharmacological interventions are analyzed. This volume offers numerous illustrative examples, including full color figures. This book serves as a valuable resource for students and researchers, assisting in the comprehension of current trends in CNS trauma and helping to stimulate the discovery of new research areas.

Book Description
Spinal cord injury induces anatomical plasticity throughout the nervous system, including distant locations in the brain. Several types of injury-induced plasticity have been identified, such as neurite sprouting, axon regeneration and synaptic remodeling. However, the molecular mechanisms involved in anatomical plasticity after injury are unclear, as is the extent to which injury-induced plasticity in the brain is conserved across vertebrate lineages. Here, I used lampreys to identify the molecular mechanisms in mediating anatomical plasticity, because lampreys undergo anatomical plasticity and functional recovery after a complete spinal cord transection. Due to their robust roles in neurite outgrowth during neuronal development, I examined synapsin and synaptotagmin for their potential involvement in anatomical plasticity after injury. I found increased synapsin I mRNA throughout the lamprey brain as well as increased protein levels of synapsin I, phospho-synapsin (Ser 9) and synaptotagmin in the lamprey hindbrain after injury, suggestive of anatomical plasticity. Anatomical plasticity was confirmed at the ultrastructural level, where I found increased neurite density in the lamprey hindbrain after injury. Other molecular mechanisms that promote anatomical plasticity have been previously identified, such as cyclic AMP (cAMP). However, the cellular mechanisms and the molecular targets of cAMP in mediating anatomical plasticity are unclear. My investigation of cAMP revealed that cAMP enhanced the number of regenerated axons beyond the lesion site in lampreys after injury. For the first time in a spinal cord injury model, I found cAMP prevented the death of axotomized neurons that normally have a high tendency to die after injury. In addition, cAMP promoted more regenerating axons to re-grow in straighter paths rather than turning rostrally towards the brain stem. At the molecular level, I found cAMP increased synaptotagmin protein level at the regenerating axon tips, suggestive of enhanced axon elongation. Taken together, my results show that neurite sprouting in the brain and the cAMP-enhanced axon regeneration are conserved responses in vertebrates after spinal cord injury. In addition, my results suggest that at least some developmental pathways are activated during injury-induced and cAMP-enhanced anatomical plasticity. Further understanding of these pathways will provide insights for improving recovery after spinal cord injury.
