Types Of Eventrelated Potentials

Model-based source localization, computational decomposition of complex responses, and quantitative estimates of the activation time courses of identified brain regions are all relatively new tools for the analysis of event-related neural electromagnetic data. However, 50 years of macroscopic electrophysiologi-

cal study ofneurological, psychological, cognitive, and behavioral processes of the human brain have produced a rich legacy of experimental observations and interpretation. Many of these results are based on the analysis of features in the response waveform, often averaged across many sensor locations and sometimes across many individual subjects. A comprehensive summary of such results is well beyond the scope of this article. Excellent review articles and even entire volumes have been devoted to small corners of the field. We will briefly review some of the major classes of event-related responses that have been identified and characterized.
