Electroencephalography (EEG) is one of the oldest neurophysiological techniques used to evaluate brain activity and is a cornerstone of technical diagnostics in neurology. The technical advancement of electroencephalography in the last few decades, however, asks for a new approach to EEG reading. This textbook and atlas provides a systematic approach to normal and abnormal EEG patterns, serving as an instructional guide for the beginner in EEG and an essential reference for the experienced EEG reader. Containing about 400 figures illustrating typical EEG patterns which are also available online in reformatted referential and bipolar montages, this book covers how electrical waves are generated into the brain, the equipment required to record electrical brain waves (including the set-up of EEG machines, electrodes, and procedures), biological and non-biological disturbances called artifacts in EEG recordings, and differentiation of normal and abnormal patterns in EEG. The reader will be introduced to a systematic analysis of EEG interpretation by defining the characteristics of the EEG patterns (polarity, localization, frequency, modulation etc.) and their clinical meaning, making this an essential text that should be on the bookshelf of every medical professional using EEG.
