Studies exploring the neural correlates of the emotion regulation strategy called cognitive change (reappraisal) have been thoroughly discussed and synthesized. This is not the case for another emotion regulation strategy called response modulation. The aim of this thesis was to conduct a systematic review on the neural correlates of one specific emotion regulation technique in response modulation, called expressive suppression. Expressive suppression is the inhibition of emotion expressive behavior. Using a systematic search, screening, and selection process, out of the initial 557 articles eight studies were included for data extraction and discussion. The studies exposed participants to negative emotion-inducing stimuli and instructed participants to either suppress their emotional behavior or to watch the stimuli without regulating the emotion. All studies used functional magnetic resonance imaging (fMRI). Expressive suppression yielded increased activation in frontal and parietal regions, especially in the right dorsolateral prefrontal cortex and bilateral inferior parietal cortex, compared to a non-regulation condition. Results of amygdala activation were inconsistent with different studies showing an increase, decrease, or no difference in activation during expressive suppression versus the non-regulation contrast condition. The thesis ends with a discussion of methodological issues and future directions.
