The aim of this extensively illustrated atlas is to better the

knowledge of visual analysis of EEGs for neurologists,

neuropediatricians, and other specialists who use

electroencephalography, as well as EEG technologists. The

first volume of this series of atlases covers the scope of the

main features of physiological EEG wake and sleep

activities in children and adults, activation procedures and

the most commonly found artifacts. Indeed, a more

thorough knowledge of these elements is necessary so as

not to misinterpret them as pathological traits. Pathological

traits will be focused on in the coming volumes. So that this

atlas can also be user-friendly for initial and advanced self-study,

the EEG plates are full-size and the characteristic

elements are reviewed and discussed in detail. Each chapter

begins with a review of technical features and a description

of physiological EEG patterns. After that, these patterns are

illustrated with a large number of EEG plates. The first

chapter indicates how to carry out visual analysis of the

usual and unusual rhythms observed in wake EEGs. The

second chapter focuses on activation procedures and

responses to hyperventilation or intermittent photic

stimulation. The third chapter deals with visual analysis of

sleep EEGs at different stages and visual analysis of their

characteristic physiological or unusual figures. The last

chapter focuses on the most common physiological and

nonphysiological artifacts.
