Investigation of Physiological and Pathological Brain Activity using EEG-Correlated fMRI

Since it has become possible to acquire EEG und fMRI data simultaneously (EEG-correlated fMRI, EEG/fMRI), this technique has been applied mainly to four fields: 1) mapping of fMRI activation associated with interictal epileptiform discharges (IED) in patients with epilepsy, 2) mapping of fMRI activation associated with physiological EEG activity, like alpha rhythm; 3) monitoring vigilance and sleep stages during fMRI experiments; and 4) simultaneous acquisition of fMRI data and evoked potentials. Here, EEG/fMRI studies of IED and alpha- and beta-rhythm are presented. Several studies have shown that EEG-correlate…
