L, left hemisphere; R, right hemisphere; BA, Brodmann area derived from sLORETA; a, b, refer to different centroid voxels of the same BA (see Table 2); r ₁, connectivity of the multi-domain group; r ₂, connectivity of the visuomotor group; r _s, the Spearman correlation (for both groups together) of the connectivity of the particular edge with performance. Connectivity values for each edge are based on instantaneous coherence measures. The network consists of 18 nodes and 20 edges. A threshold of t = 3.6 was applied
