Abstract

A single dipole source was chosen as a model of the neurological generator of evoked potentials elicited by illuminated checker-board stimulation of halves and quadrants of the visual field, and a homogeneous sphere was chosen as a model for the head. Dipole locations and moments were calculated for the average evoked potentials and average dipole locations and moments were calculated for the preprocessed single evoked potentials. The average dipole locations for the single potentials appear to be more anatomically appropriate than the location due to the average evoked potentials. A relationship was demonstrated between the dipole parameters and polarity inversions in the average evoked potentials.
