The normal EEG in an adult

Abstract

When an experienced electroencephalographer sits down to review an EEG, whether obtained on a pen/ink-based analog machine or from the cathode ray tube screen of a digital device, a number of mental integrations take place seamlessly. This chapter addresses the normal EEG observed in people older than 18 yr of age. Topics to be covered include the normal waking background rhythm (alpha rhythm); beta activity; mu, theta, and lambda waves; activation effects on the EEG; and features of normal sleep. © 2007 Humana Press Inc.
