cognitive conflict과 관련된 뇌 영역으로는 anterior cingulate cortex와 prefrontal cortex 가 주로 언급되어 왔다. Emotional conflict는 주로 어떤 영역과 어떻게 관련이 있을까? 최근연구는 아니지만, 2006년 Neuron에 실린 논문을 소개한다. amygdala와 prefrontal cortex가 emotional conflict와 관련이 있다는 결과와 함께 DCM을 사용하여!!!  amygdala와 cingulate 간의 causality 를 보았다.

Etkin A. et al. (2006). Resolving Emotional Conflict: A Role for the Rostral Anterior Cingulate Cortex in Modulating Activity in the Amygdala. Neuron 51, 1-12,

Effective mental functioning requires that cognition be protected from emotional conflict from interference by task-irrelevant emotionally salient stimuli. The neural mechanisms by which the brain detects and resolves emotional conflict are still largely unknown, however. Drawing on the classic Stroop conflict task, we developed a protocol that allowed us to dissociate the generation and monitoring of emotional conflict from its resolution. Using functional magnetic resonance imaging(fMRI), we find that activity in the amygdala and dorsomedial and dorsolateral prefrontal cortices reflects the amount of emotional conflict. By contrast, the resolution of emotional conflict is associated with activation of the rostral anterior cingulate cortex. Activation of the rostral cingulate is predicted by the amount of previous-trial conflict-related neural activity and is accompanied by a simultaneous and correlated reduction of amygdalar activity. These data suggest that emotional conflict is resolved through top-down inhibition of amygdalar activity by the rostral cingulate cortex.
