This book is a primer on clinical neurophysiology centering on EEG and evoked potentials. Its goal is to introduce learners to the engineering, physiological, and clinical underpinnings of EEG and evoked potentials. Chapters follow a case-based format and offer a visual schematic or a patient-derived example, followed by a clear teaching point that's reinforced by a series of questions by which the student can self-test. "Fundamental" chapters provide basic elements of engineering or physiology; "Cases" illustrate disease entities or their mimics. Pearls of EEG will be of interest to a variety of subspecialists, including EEG technologists, medical students, neurology residents, and fellows in clinical neurophysiology, epilepsy, neuro-critical care, pediatrics, neonatologists, neurological hospitalists, or sleep.
