Figure 6. Future potential of M/EEG-fMRI fusion.
(A) M/EEG fMRI fusion may be applied in any field in which both M/EEG and fMRI are already applied in isolation. (B) M/EEG fMRI fusion may be combined with brain stimulation to reveal its effects and to establish causal relationships between neural responses and behavior. (C) Innovation in M/EEG and fMRI research can be directly harvested by fMRI fusion to reveal novel aspects of neural processing. For example, feed-forward and feedback information flow are associated with neural responses in distinct cortical layers and in distinct frequency bands. Thus, fusing M/EEG data resolved in different frequency bands with fMRI data resolved in cortical depth may reveal feed-forward and feedback information flow in the brain.
