dmPFC:
"The most dorsal part of medial frontal cortex—the dmPFC—may have a specialized role in encoding key features of the structure of the social environment and the position of the decision maker within this social environment."
"In addition, we also expected that empathy for social exclusion would engage neural regions supporting mentalizing processes (e.g., DMPFC)."
"Observing exclusion (vs. inclusion) activated regions associated with mentalizing (dorsomedial prefrontal cortex, medial prefrontal cortex, precuneus), and highly empathic individuals activated both mentalizing regions and social pain-related regions (anterior insula, dorsal anterior cingulate cortex). Additionally, the empathy-related activity in the anterior insula and medial prefrontal cortex was associated with later prosocial behavior toward the victim, and exploratory mediation analyses indicated that medial prefrontal cortex activity, in particular, may support the link between trait empathy and prosocial behavior. Overall, findings suggest that empathy-related neural responses to social experiences may promote spontaneous prosocial treatment of those in need."
