Mapping brain activity using event-related independent components analysis (eICA): Specific advantages for EEG-fMRI

► We describe an event-related independent components analysis (eICA). ► We analyse EEG-fMRI data from a group of benign rolandic epilepsy patients. ► Conventional event-related analysis of the data provided no group localisation. ► eICA provided localisation concordant with the presumed epileptogenic focus.
