Outline of Final Research Achievements

We aim to resolve the spatiotemporal changes in brain activation using simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) recordings. We proposed a method that employed whole scalp EEG data to generate regressors needed for the analysis of fMRI using the general linear model. Using simultaneous EEG-fMRI recordings from healthy subjects and patients with epilepsy, we obtained activation maps showing brain regions that were consistent with working memory task and suspected or confirmed sources of the epileptogenic activity. We also identified spatiotemporal activation patterns during epileptic spikes that include sequential activation of multiple brain regions involved, shifting location of the peak activation, and local spreading of activated regions. These findings demonstrated the efficacy of the method in resolving rapidly changing activation patterns with sub-second temporal resolution observed during cognitive task and epileptic spikes.
