Normal Awake Adult EEG

  • Chapter
Clinical Electroencephalography

Abstract

In the first part of this chapter, the principal characteristics of electroencephalographic (EEG) signals (morphology, amplitude, location, rhythmicity, symmetry, etc.) and the wide spectrum of EEG frequencies, grouped in bands, are described. In the second part, the physiological rhythms and the normal graphoelements of the waking adult EEG are detailed, with particular reference to the alpha and mu rhythms. Finally, the intra- and interindividual variability, the aging effects on EEG and the concept of EEG normality are briefly discussed.
