The EEG/MEG-informed fMRI analysis rests on the fMRI analysis frameworks (e.g. the GLM analysis) while incorporating temporal- or frequency-specific information available in EEG/MEG. Such a multimodal strategy differs from the conventional fMRI analysis in its unique ability to selectively localize the fMRI correlates to specific neuronal events or rhythms. This ability directly benefits from the EEG/MEG measurements which reflect the mass neural responses, whereas the analysis based on fMRI alone relies on the timing of the stimuli or tasks. Note that the approaches in this category usually prefer EEG to MEG due to the highly desired simultaneous recordings of fMRI and electrophysiological signals.
