From the reviews: Normal findings, abnormal findings and artifacts seen in electroencephalography (EEG) studies during polysomnography are presented in this atlas. The book is written for physicians trained in internal medicine, otolaryngology, neurology, pediatrics, psychiatry, and pulmonary medicine who go on to practice clinical sleep medicine. This is a much needed resource. The text is concise and the images are relevant. The information is presented well and will likely be helpful to those who are not formally trained in EEG.
