Abstract

This article reviews several approaches that historically have been used to identify the generators of auditory evoked potential (AEP) peaks. Then, various imaging modalities are reviewed, which include source localization of multichannel AEP recordings, functional magnetic resonance imaging (fMRI), and positron emission tomography (PET). The strengths and weaknesses of these imaging modalities are considered. The role of source localization, fMRI, and PET in the identification of AEP peak generators is entertained. We review some evidence that includes modeling data, as well as empirical evidence, using both PET and source localization approaches. We conclude that source-localization and/or functional-imaging approaches will not help substantively in the identification of AEP generators, at least using current approaches.
