Emotion regulation, which refers to the flexibility of responses to affective events, plays an important role in our daily social life. An appropriate regulation could benefit to our mental and physical well-being. The present study attempts to explore the neural substrates underlying the following three emotional regulation strategies: distraction, reappraisal and expressive suppression. Thirty-two young adults completed an emotion regulation task, which instructed participants to apply different strategies to regulate their emotional states when viewing negative, neutral and positive pictures during a fMRI scanning. Our findings revealed that when compared to reappraisal and suppression, distraction activated larger clusters of the inferior parietal cortex, the left superior parietal cortex, the right angular gyrus, the right middle frontal cortex, the SMA as well as partial right insula. While the dorsolateral, ventrolateral and dorsomedial prefrontal cortex (dlPFC, vlPFC, dmPFC), the orbitofrontal gyrus, the middle temporal cortex, the angular gyrus, the hippocampus, and the post cingulate gyrus were recruited in reappraisal as compared to distraction. However, only smaller clusters of the middle temporal cortex, the vlPFC and the left dmPFC were found as compared to suppression. Suppression showed increased activation of the dmPFC, the left dlPFC, the orbitofrontal gyrus, the middle and the superior temporal cortex as compared to distraction, but no significant differential activation was observed when compared to reappraisal. In general, these results suggest that reappraisal and expressive suppression recruited very similar emotion regulation networks in the prefrontal cortex, while distraction had a stronger correlation with activation of the parietal lobe.
