Neural activity associated with own reward and empathic reward. (A) Neural activity associated with own reward (red, Δ neural activity correct-incorrect response) in the VS/mOFC and neural activity modulated by behavioural similarity in the vACC (orange, Δ similarity _LP-NLP x Δ neural activity goal-no goal _LP-NLP). Statistical parametric maps are thresholded at a voxel-wise height threshold of p = 0.001 and superimposed onto sections of a T1-weighted map of a standard brain (MNI). Functionally defined ROIs in the VS and mOFC (from which data in B,C were extracted) are shown in yellow. (B,C) Correlation between differences in behavioural similarity and differences in empathic-reward related neural activity in the left VS and mOFC. Each dot denotes a participant. Asterisks indicate significant effects (p < 0.05). LP, player who supposedly executed 75% of the shots; NLP, player who supposedly executed 25% of the shots. VS, ventral striatum, mOFC, medial orbitofrontal cortex, vACC, ventral anterior cingulate cortex.
