  Simultaneous acquisition of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) aims to combine the strength of both methods by investigating brain activity with the high temporal resolution of the former and the good spatial precision of the later. However, simultaneous EEG-fMRI measurements are technically challenging because both methods interfere with the other modality. The main confounding factors are the pulse artefact (PA) caused by pulsatile motion linked to the cardiac cycle and the gradient artefact (GA) produced by the temporally varying magnetic fields required for MR imaging. Both of these artefacts are orders of magnitude larger than the neuronal activity of interest, but their inherent periodicity facilitates reasonable artefact correction by post-processing techniques such as average artefact subtraction (AAS), Optimal Basis Set (OBS).
