Figure 5. A summary of the findings of this study.

The shapes represent brain areas (MFG, insula and a putative intermediate brain area). The lines with two arrowheads represent FC. 5a corresponds to the pattern of the insular network of the amateurs in this study and in Cauda et al.'s study 5b corresponds to the pattern observed in the insular network of the experts. Note that 5b shows an expanded transitional subregion (the dotted line circle) and a direct connection between the MFG and posterior subregion (purple line).
