EEG interpretation remains an art as well as a science, grounded in not just knowl­edge of electronics and neurophysiology, but also in the ability to recognize patterns that consist of both visual and clinical data. This collection is not intended to be ency­clopedic, but rather practical, highlighting the clinical role of EEG interpretation, and the need to consider and rule out artifacts of various types EEG interpretation is best learned in the context of real cases. The atlas includes 80 case studies, illus­trated as screenshots, as they may present in daily practice; they encompass a wide spectrum, ranging from common situations found on routine recordings, to under-rec­ognized or exceptional patterns seen in ICU patients, including newborns. The form is that of a quiz: in the first part the images are preceded by a brief clinical description to orient the interpretation. After analyzing each case, the reader may confront his/her guess with the corresponding description found in the second part. In particular, this book will help with the in­terpretation of uncommon normal variants, features of unknown significance, and dif­ferent sorts of artifacts; some practical tips are also scattered in the text.
