Here we present a method capable of suppressing motion-related EEG GA instabilities, induced EEG voltages and fMRI artefacts in simultaneous EEG-fMRI data. This correction method appeared to allow for the removal of harmonics associated with incomplete GA removal even in a moving subject. Therefore our findings might be helpful in improving both EEG quantification reliability and data quality in populations prone to movement e.g. children or for studying patients with epilepsy during seizures.
