Dorsal and ventral communities for Sadness-Working memory. (A) 3D-graphical representation of the networks, the ROIs are located according to real-world coordinates. Mean significant correlations are plotted; positive correlations in red lines and negative correlations in blue dashed lines, shading brain for schematic purposes. (B) Matrix of the mean correlations across subjects. The analysis identified two main modules (Fig. S2A), the dorsal and ventral communities separated by the dashed black line. In the ventral community, two sub-communities were found (separated by the red line), corresponding to the emotional areas in the cortex and the limbic system (subcortical areas). (C) Correlation distributions for all subjects. The correlations between dorsal and ventral modules (inter-modules), plotted in blue were mainly negative (mean ± SEM = −0.15 ± 0.004). The correlations within the dorsal module (intra-dorsal, plotted in orange, mean ± SEM = 0.089 ± 0.005) and the correlations within the ventral module (intra- ventral, plotted in red, mean ± SEM = 0.048 ± 0.009) were both positively biased.
