EaI, Empathy after Interoception; EaE, Empathy after Exteroception; PCC, posterior cingulate cortex; DMPFC, dorsomedial prefrontal cortex; SACC, supragenual anterior cingulate cortex; MPC, medial parietal cortex. The global height threshold was set to P < 0.001 uncorrected, the extent threshold to k = 5 voxels for all contrasts. The values in the table represent maximum z values with peak voxel coordinates in the MNI stereotactic space.
