EEG Source Imaging Guided by Spatiotemporal Specific fMRI: Toward an Understanding of Dynamic Cognitive Processes

Figure 5

Source imaging results comparing two EEG/fMRI integration approaches: time-invariant fMRI constraints ((a1), (a2); (b1), (b2); (c1), (c2)) and spatiotemporal fMRI constraints ((a3), (a4); (b3), (b4); (c3), (c4)) at two time instances to demonstrate visual activation ((a1), (a3); (b1), (b3); (c1), (c3)) and motor activation ((a2), (a4); (b2), (b4); (c2), (c4)). Source activity shown is color coded as a percentage of its maximum.
