PPI analysis of connectivity of the medial orbitofrontal cortex (mOFC). The mOFC as the seed shows increased negative connectivity with the right primary somatosensory cortex (SI) in the hand area contralateral to the stimulation site, the right rostral anterior insula (raINS), and the anterior-dorsal anterior cingulate cortex (adACC). Subdivision of the ACC according to Etkin et al. (2011); pd, posterior-anterior; pg perigenual; sg, subgenual. Images are displayed in neurological convention, i.e. right side of the brain is on the right. Statistical inference was based on a voxel-based threshold of z = 1.6 and cluster threshold of P < 0.05 within the regions of interest anterior insula, ACC, and SI (postcentral gyrus). Coordinates are given in MNI space.
