Dipole source analysis. Linking scalp potentials to their generating neuronal structures.
The spatiotemporal approach of dipole source analysis is a crucial methodological advance in event-related potential research, as overlapping subcomponents of cortical evoked potentials can be separated and related to their generating structures. This enhances the reliability and validity of event-related potential parameters and facilitates the link to underlying neurochemical processes. The present paper presents methodological aspects of the dipole source analysis of auditory-evoked potentials to different stimulus intensities.
