    Summary: As a single-source volume on intraoperative neurophysiological monitoring (IOM), previous editions of this celebrated resource amounted to a mission statement from the pioneer generation in intraoperative neurophysiology, converting insights, techniques, and perspectives into tools providing clinical utility for the assessment of the nervous system in patients who could not be assessed by a standard neurological examination. Now directed by a new generation of experts, this thoroughly illustrated Third Edition is updated with new case material, images, videos, practice guidelines, references, and technologies, and is intended for those who encounter IOM in the operating room and intensive care unit, including anesthesiologists, technologists, neurophysiologists, surgeons, and nurses, as well as graduate students and trainees. Offering topical, applicable information, this accessible reference and teaching tool provides practical knowledge to help students, trainees, and team members better understand one anothers roles, thereby improving patient safety and care.
