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.

Mentions: For the congruency effect, the activation of several voxles located in the right DLPFC (x = 48, y = 18, z = 27) (P < 0.05 SVC corrected) was observed; those voxels showed higher activation for incongruent trails compared with congruent trials. This result is displayed in Fig. 2A. For the effect of emotional face valence, no voxels showed significant activation for the contrast of negative minus positive at the level of P < 0.05, FWE corrected. The Paired t-test for the contrast of (P (i − c)−N (i − c)) resulted in several regions, including the posterior cingulate cortex (PCC) (−15, −75, 24), precuneus (−18, −72, 33), inferior parietal lobule (IPL) (−36, −45, 57), the fusiform gyrus (FFA) (30, −60, −12), middle occipital gyrus (MOG) and the middle temporal gyrus (MTG) (42, −75, 0). These regions were remained significant at a significance level of P < 0.05, FWE corrected. These results are presented in Fig. 2B1. In addition, activity patterns across four experimental conditions in areas associated with emotional faces processing were showed in Fig. 2B1 (the bottom panel). Other activation during the Paired t-test was found in the Table 1.
