Techniques using evoked spinal cord potentials (SCPs) have become important clinical tools for monitoring spinal cord surgery and diagnosing spinal cord diseases. This book surveys the neurophysiological and neuropharmacological bases of evoked SCPs with reference to animal studies and to recording those potentials mainly from the spinal epidural space. Generous use of illustrations promotes understanding of the neurophysiological and neuropharmacological backgrounds of monitoring spinal cord functions, and case studies provide additional insight into the monitoring and diagnosis of spinal cord dysfunction and disease. The book is especially useful for students and those new to the fields of clinical neurophysiology, neurosurgery, neurology, orthopedics, and neuroanesthesia. No other text sets forth the terminology of the components of evoked SCPs as clearly as this volume does with its careful use of lucid explanations and illustrations.
