Figure 4

Spatial topological differences between unimodal and multimodal streams. The left insula and left anterior cingulate cortex (ACC) were selected as regions of interest (ROIs) and the Euclidean distance in the 3D anatomical space between ROI’s center of gravity and peak FC voxels was computed. Top panel: Euclidean distance did not report significant differences between unimodal and multimodal streams. Bottom panel: Significant differences were observed between the delta shift (Euclidean distance) of the left insula and the left ACC.
