Model of brain regions involved in moral cognition: the frontal pole (yellow), rostral anterior cingulate cortex (red), left superior temporal sulcus (green), and precuneus/ posterior cingulate cortex (blue). Effective connectivity within a hypothetical neural network involved in the implicit recognition of moral issues (FP: frontal pole; rACC: rostral anterior cingulate cortex; STS: left posterior superior temporal sulcus; PCC: precuneus/posterior cingulate cortex). Circles highlight significant path coefficients.
