This practical handbook covers all the key aspects of EEG interpretation. Arranged in an easy-to-use format, the text covers the value of EEG, practical tips on interpretation, specific areas where EEG is most useful, pitfalls to avoid, how to report the findings, and explanations of the most prominent EEG phenomena. And, it provides readers with a comprehensive mini-atlas of EEG tracings.
