The dorsal part of the anterior cingulate cortex is associated with cognitive tasks, while ventral and subgenual areas are activated by emotional valence in conflict tasks.

“So the dorsal part of the anterior cingulate seems to be kind of more of a pure cognitive, maybe obsessive compulsive disorder sort of area. Whereas when you start getting into mood sorts of triggers, like facial expression conflicts where you're supposed to, you know, there's an emotional Stroop task where you show the word happy and then you have a face of a person that looks mad, then that's another way of having the same sort of Stroop conflict. That seems to be more perigenual, subgenual areas, right?”
