Figure 9. — The projection of source power comodulation (SPoC) and common spatial patterns (CSP) components in source space confirms the link between emotional arousal and alpha oscillations in parieto-occipital regions. Colours represent the inversely modelled contribution of the cortical voxels to the respective spatial pattern yielded by SPoC or CSP (max: component maximizing power for epochs of high arousal; min: component minimizing power for epochs of high arousal). We applied the same normalization and averaging procedures as for the topoplots in Figure 6. Upper row: averaged across all subjects per condition (nomov, mov). Lower row: patterns of one individual (the same as in Figure 7).
