Electroencephalography, Evoked Potentials, and Event-Related Potentials

Abstract

This chapter aims to provide background knowledge necessary to understand electroencephalography (EEG) technique and its applications. First, the information about how EEG, evoked potentials (EPs), and event-related potentials (ERPs) are generated and obtained are summarized. Next, a brief overview of EPs and ERPs is provided, and classical EP and ERP components that are applied in clinical and neuroscience studies are also described, with an emphasis on different sensory modalities through which the stimuli are presented. Finally, the pitfalls and promise in EP and ERP studies are discussed.
