Preface

This primer is written as a brief introduction to EEG that can be read on the first day as someone is exposed to an EEG for the first time. It is not meant to be a comprehensive text. There are many textbooks available that go into much more detail. The goal is to review the principles of EEG and give examples of EEG findings encountered on a routine day of EEG reading. Therefore, subjects such as neonatal EEG and full treatment of EEG interictal and ictal patterns are not included.
