This is the first book devoted exclusively to examining the role of neuropeptides in the spinal cord. Great progress has been made recently in our understanding of the role of neuropeptides in neurotransmission. New tools have been developed to help study the function of endogenous neuropeptides in health and disease. Because the general organization of the spinal cord is well conserved among species and neuropeptides appear to have a major role in spinal neurotransmission, this book is a timely compendium of recent research in this field. The volume will help to stimulate further research in the field of neuropeptides which will lead to better understanding of this role in health and disease.
