Figure 6.

Functional heterogeneity within functionally flexible regions. The figure shows cortical regions participating in multiple cognitive components of the 12-component estimate. Functionally flexible regions were mostly located in the frontal and parietal lobes. These functionally flexible regions are functionally heterogeneous. For example, the top 4 components activating an anterior insula/operculum (aIns/Oper) region (−34, 16, −2) were C8, C5, C12, and C7, with corresponding Pr(component | aIns/Oper) equal to 0.20, 0.19, 0.17, and 0.15, respectively. In contrast, the top 4 components activating an aIPS region (−45, −43, 43) were C9, C1, C4, and C6, with corresponding Pr(component | aIPS) equal to 0.23, 0.21, 0.16, and 0.13, respectively. There was heterogeneity even within a functionally flexible zone, for instance across the IPS. For example, in contrast to aIPS, the top 4 components activating a pIPS region (−26, −63, 45) were C9, C5, C6, and C4, with corresponding Pr(component | pIPS) equal to 0.36, 0.24, 0.20, and 0.08, respectively. The Desikan–Killiany atlas (Desikan et al. 2006) was used to guide the labeling of the regions aIns/Oper, aIPS, and pIPS.
