Topographic mapping of brain electrical activity in the assessment of central auditory nervous system pathology.
Topographic mapping of brain electrical activity is a method of converting electrical measurements of brain activity (evoked potential and EEG) into quantitative data that then can be displayed as colored visual maps. In this article, we review the basic principles underlying the procedures involved and then discuss their use in the assessment of central auditory nervous system (CANS) pathology. Finally, we highlight some of the limitations of the procedures as presently used.
