We have acquired fMRI and 32-channel EEG data simultaneously with a 3.0 Tesla MRI system. For the simultaneous data acquisition, we used an interleaved fMRI-EEG scheme with visual motion stimuli. The ballistocardiogram (BCG) artifacts in the EEG data have been removed by the correlative template subtraction technique. The EEG source localizations have been performed with the cortically constrained inverse BEM model. The temporal information from EEG source localization has been used to resolve the temporal behavior of fMRI. We found that the EEG source localization can be used to enhance the temporal performance of fMRI if activated regions are separated far apart.
