Abstract
The topography of event-related potential (ERP) maps reflects the intracranial distribution of neural activity. Map topography can be quantified by spatial features, such as the locations of map maximum and minimum potentials, the locations of the centroids of the positive and the negative scalp sites versus the average reference, or the parameters of equivalent dipoles. Such spatial features usually offer significant data reduction compared to the original maps and retain their robust topographic characteristics. Space-oriented ERP map analysis (Lehmann and Skrandies, 1984) is based on the extraction of such spatial map descriptors. The method can provide critical evidence about the nature of the ERP changes, and can distinguish whether brain activity patterns are altered, attenuated, or delayed (e.g., Brandeis and Lehmann, 1989; Brandeis, Naylor, Halliday, Callaway, and Naylor, 1992).
