Voxel-level parcellation of the left anterior cingulate cortex (ACC) based on its functional connectivity in healthy individuals with other brain areas. The correlations (r) are the distance from the centre of the circular plot. The pregenual and subcallosal subdivision (1, green) has strong functional connectivity with the medial orbitofrontal cortex and connected areas (AAL2 areas from OLF to OFCpost). The supracallosal subdivision (2, red) has strong functional connectivity with the lateral orbitofrontal cortex area IFGorb and with adjacent inferior frontal gyrus areas (IFGtriang to IFGoperc). The parcellation was similar on the right. The AAL2 is the automated anatomical labelling atlas, which shows the abbreviations used (Rolls et al. 2015)
