ABSTRACT:
A method is disclosed for utilizing brain evoked potentials for characterizing brain pathology. A brain electrical activity map is prepared from a patient's evoked potential data, and the centers of gravity of peaks of the evoked potential are calculated for a sequence of frames of the map, and plotted in a single frame to provide a spatial trajectory which may then be compared to a patient norm in order to detect and characterize brain pathology.
