Regions that were significantly positively correlated with medial prefrontal cortex (mPFC) to a greater degree when participants made economic decisions as they interacted with others in the high sociality condition compared to the low sociality condition: r refers to the Pearson correlation coefficient relating neural activity in that cluster and mPFC activation coefficients at the group level.
