Book Description
Experimental methods for the mapping of nervous pathways are based partlyon the study of retrograde processes in the perikaryon, partlyon the demonstration of degenerative processes along the peripheral part of a transected axon. For this purpose, the Marchi method by which a selective staining of degenerating myelin is obtained has been extensively used. However, when this method is used the non-myelinated terminals of the transected axons are not stained. The introduction, about two decades ago, of silver impregnation as a means of tracing degenerating axons (especially the Glees and Nauta methods) by which also terminal boutons can be demonstrated, led therefore to revolutionary progress in the investigation of interneuronal connections. Notwithstanding, there are weH known difficulties involved in this kind of research. The capriciousness of the silver methods not seldom results in failure of impregnation with loss of valuable experimental animals. But even when well impregnated sections are used, other fundamental difficulties exist. One of the major problems is to prove beyond doubt that the impregnated structures are degenerating boutons and not merely fragments of non-terminal fibres passing the area under examination. Furthermore, only on occasion will silver impregnation permit one to accurately define the specific part of the receiving neuron on which the impregnated fibres end, i. e. , whether the bouton makes contact with soma, dendrite or spine.

Book Description
This book is a collection of classical as well as innovative methods used to investigate axon degeneration with a particular focus on addressing the common challenges encountered while performing these procedures. Particular attention is devoted to the study of axon loss in several model organisms, as each poses unique challenges and provides powerful advantages. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Axon Degeneration: Methods and Protocols is an ideal guide for facilitating the application and further development of these protocols, which will help the scientific community tackle important questions regarding axon degeneration. Chapters 2, 3, and 20 are available Open Access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Book Description
The axon, interposed between the cell body and the synaptic terminals in most neurons, plays a crucial role in connecting neurons and acting as a conduit for the transmission of information between them. This book provides a comprehensive and up-to-date compendium that brings together chapterson the structure, function, and pathophysiology of axons in both the PNS and CNS. Carefully written, well-illustrated with superb illustrations, and generously referenced, the 33 chapters and introduction have been authored by 49 world-renowned authorities. Recent advances in the molecularneurobiology of axons are carefully reviewed, and new areas, such as the molecular biology of ion channels and myelination, the role of calcium in pathophysiology and regeneration, cell adhesion molecules and their roles in axo-glial interactions and axonal guidance, and optical recording methods,are highlighted. This book will provide an essential reference for neuroscientists as well as clinicians such as neurologists, neurosurgeons, and clinical electrophysiologists interested in axons.

Book Description
This book provides a practical guide to the field of neuromuscular pathology including muscle, peripheral nerve, and skin biopsies with biopsy interpretation. Divided into three parts, the book begins with introductory chapters that review muscle, nerve, and skin biopsy indications and procedures, normal muscle and nerve histology, and common muscle and nerve pathology. The 28 myopathy case chapters in Part 2 and 11 neuropathy case chapters in Part 3 illustrate the clinical and pathological features of many neuromuscular diseases, demonstrate the indications and utilities of biopsies, discuss clinical and pathological differential diagnosis, update the individual disease management, and summarize pertinent clinical and pathology pearls for each case. A Case-Based Guide to Neuromuscular Pathology will function as an indispensable reference for neurologists and pathologists looking to understand the utility of muscle, nerve, and skin biopsies. This book will also aid neurology residents, neuromuscular fellows and neuropathology fellows in preparing for questions related to the muscle and nerve pathology in their in-service and board exams.
