Abstract: Theoretical perspectives suggest that the mirror neuron system (MNS) is an important neurobiological contributor to empathy, but empirical support is mixed. Here, we adopt a summary model for empathy, consisting of motor, emotional, and cognitive components of empathy. This review provides an overview of existing empirical studies investigating the relationship between putative MNS activity and empathy in healthy populations. 52 studies were identified that investigated the association between the MNS and at least one domain of empathy, representing data from 1044 participants. Our results suggests that emotional and cognitive empathy are moderately correlated with MNS activity, while motor empathy showed no relationship. Results varied across techniques used to acquire MNS activity (TMS, EEG, and fMRI). Overall, results provide some evidence for a relationship between the MNS and empathy. Our findings also highlight methodological variability in study design as an important factor in understanding this relationship. We discuss limitations regarding these methodological variations and important implications for clinical and community translations, as well as suggestions for future research.
