About the book: Standing alone as the first definitive and comprehensive book on the subject, this guide describes the most recent studies on the brain-gut connection and psychosocial issues related to patients experiencing visceral pain. Bringing together leading experts from the top-tiers of the science, this source provides 33 engaging chapters and spans basic concepts in pharmacology, neurobiology, physiology, and psychology to provide a practical approach to the treatment of chronic pain. Examining a condition that affects up to 25% of the general U.S. population, this source is the only book on the subject to cover both clinical syndromes and neurobiology and ranges from basic mechanisms to diagnosis and clinical treatment of specific syndromes including inflammatory bowel disease, functional abdominal pain, dyspepsia, non-cardiac chest pain, and pelvic pain syndromes; analyses the latest scientific advances including the role of functional imaging in patient care; integrates fundamental scientific concepts with a practical clinical approach; and; supplies 250 figures, and more than 16 color photographs. About the editors: P.Jay Pasricha is Chief, Division of Gastroenterology research that includes pain and motility disorders. Dr. Pasricha has served on numerous national gastroenterological committees and on NIH panels. He holds several patents related to gastrointestinal diagnostics and therapeutics and is a consultant to many companies.

As stated in the preface to the first edition, the goal of this monograph is to provide an overview of current thought about the spinal cord mechanisms responsible for sensory processing. We hope that the book will be of value to both basic neuroscientists and clinicians. The organization of the monograph has followed the original plan in most respects, although the emphasis has changed with respect to many topics because of recent advances. In particular, a substantial increase in the number of investigations of the dorsal root ganglion has led us to devote a chapter to this topic. The treatment of chemical neuroanatomy in the dorsal horn, as well as the relevant neuropharmacology, has also been expanded considerably. Another major emphasis is on the results of experiments employing microneurography in human subjects. We thank Margie Watson and Lyn Schilling for their assistance with the typing and Griselda Gonzales for preparing the illustrations.

The third edition of this monograph continues to have the goal of providing an overview of current thought about the spinal cord mechanisms that are responsible for sensory processing. We hope that the book is of value to both basic and clinical neuroscientists. Several changes have been made in the presentation, as well as additions because of the research advances that have been made during the past decade. Chapters 3 and 4 in the previous edition have been subdivided, and now the morphology of primary afferent neu rons of the dorsal root ganglia is described in Chapter 3 and the chemical neuroanatomy of these neurons in Chapter 4. The description of the dorsal horn in the previous Chapter 4 is now included in Chapter 5, and the chemical neuroanatomy of the dorsal horn in Chapter 6. Furthermore, discussions of the descending control systems have now been consolidated at the end of Chapter 12. The authors would like to express their appreciation for the help provided by several individuals. R.E.C. wishes to acknowledge the many things he learned about primary afferent neurons from conversations with Dr S. N. Lawson. He also thanks Lyn Shilling for her assistance with the typing. WDW thanks Dr Nada Lawand for her critical reading of parts of the manuscript, Rosaline Leigh for help with the manuscript, and Griselda Gonzales for preparing the illustrations.

The spinal cord has a characteristic structure and functions that are distinct from those of the brain. Its functions are tremendously important since it modulates the peripheral sensory inputs to the dorsal horn, and it gives rise to the ascending pathways transmitting peripheral afferent inputs to the brain, and conveys the descending pathways from the brain both to the lower motor neurons, the final common pathway, and to dorsal horn sensory neurons. In spite of these vital functions, the spinal cord constitutes only a small percent age of the mass of the human central nervous system and is located far from the skin surface, which has obstructed the recording of its electrical activity. Recently, however, important advances have been made in several recording techniques, including epidural recording or averaging methods, allowing both sensory and motor evoked spinal cord potentials in man to be recorded. This volume is based on the papers presented at the Fourth International Symposium on Spinal Cord Monitoring and Electrodiagnosis. Each of these international symposia has brought together many of the specialists involved in this research, with an important increase in the number of participants since the first symposium was held in Toyko in 1981. At the past symposia several attempts were made to standardize data, techniques, and clinical applications and to integrate the new findings into patient care."

This text provides an historical and contemporary overview of an active field of neuroscience research on somato-visceral sensation. Medical (and indirectly veterinary) implications are emphasized. Extensive revisions have been made since the last edition, including the addition of two chapters. Many significant literature citations have been added for the period since the last edition. The illustrations have been substantially expanded, including a number that emphasize newly applied techniques.
