Bottom Line: The prefrontal cortex is responsible for emotional conflict resolution, and this control mechanism is affected by the emotional valence of distracting stimuli.Importantly, these visual areas negatively coupled with the dorsolateral prefrontal cortex (DLPFC).This study thus provides a plausible mechanism of emotional conflict resolution that the rapid pathway for negative emotion processing efficiently triggers control mechanisms to preventively resolve emotional conflict.

ABSTRACT
The prefrontal cortex is responsible for emotional conflict resolution, and this control mechanism is affected by the emotional valence of distracting stimuli. In the present study, we investigated effects of negative and positive stimuli on emotional conflict control using a face-word Stroop task in combination with functional brain imaging. Emotional conflict was absent in the negative face context, in accordance with the activation observed in areas regarding emotional face processing (fusiform face area, middle temporal/occipital gyrus). Importantly, these visual areas negatively coupled with the dorsolateral prefrontal cortex (DLPFC). However, the significant emotional conflict was observed in the positive face context, this effect was accompanied by activation in areas associated with emotional face processing, and the default mode network (DMN), here, DLPFC mainly negatively coupled with DMN, rather than visual areas. These results suggested that the conflict control mechanism exerted differently between negative faces and positive faces, it implemented more efficiently in the negative face condition, whereas it is more devoted to inhibiting internal interference in the positive face condition. This study thus provides a plausible mechanism of emotional conflict resolution that the rapid pathway for negative emotion processing efficiently triggers control mechanisms to preventively resolve emotional conflict.

PPI results for negative and positive face contexts.(A) In the negative face context: negative coupling patterns between the seed region (DLPFC) and brain regions associated with emotional conflict processing. (B) In the positive face context: negative coupling patterns between the seed region (DLPFC) and brain regions in DMN (PCC/precuneus, IPL), as well as MTG.

Mentions: One-sample t-test of PPI showed that during the negative face condition, the DLPFC negatively connected with the FFA (30, −45, −12), the AI (48, −24, 15), the MTG (48, 0, −30) and the MOG (−45, −75, −12) during the process of conflict control. In contrast, during the positive face condition, the DLPFC negatively coupled with the MTG (54, −6, −21), the PCC/precuneus (3, −48, 30), and the IPL (51, −45, 24). All the regions were remained significant at the level of P < 0.005, uncorrected. The results are presented in Fig. 4. In the meanwhile, Fig. 3B illustrated the plausible neural mechanism of emotional conflict control, of which negative emotions rapidly trigger DLPFC through the subcortical route, and then, DLPFC inhibited emotional conflict timely in the visual cortical areas.
