There is no consensus regarding the optimal EEG source reconstruction algorithm, nor a systematic comparison between sets of fMRI-derived spatial priors to be included in the inversion models. We compared four inversion algorithms, each with three sets of fMRI-derived spatial priors consisting of task activation maps, resting-state networks and, for the first time, dynamic functional connectivity states. We found that combining a beamformer with these priors improves the reconstruction quality, especially in terms of the overlap with task-related brain regions of interest and RSN templates. Our results may guide more informatively the selection of the optimal EEG source reconstruction approach.
