Abstract

A method for the localization of dipoles evaluated by electrical evoked potentials (EEP) into a realistic head shape obtained by MRI is implemented. The EEP/MRI integration is achieved by fitting the reference sphere used during dipole calculation to the MRI volume. Results obtained from normal subjects after visual and somatosensory stimulation are presented.
