- Empathy by default: correlates in the brain at restPublication . Silva, Patrícia Oliveira; Maia, Liliana; Coutinho, Joana; Frank, Brandon; Soares, José Miguel; Sampaio, Adriana; Gonçalves, ÓscarBackground: Empathy, defi ned as the ability to access and respond to the inner world of another person, is a multidimensional construct involving cognitive, emotional and self-regulatory mechanisms. Neuroimaging studies report that empathy recruits brain regions which are part of the social cognition network. Among the different resting state networks, the Default Mode Network (DMN) may be of particular interest for the study of empathy since it has been implicated in social cognition tasks. Method: The current study compared the cognitive and emotional empathy scores, as measured by the Interpersonal Reactivity Index, with the patterns of activation within the DMN, through the neuroimaging methodology of resting-state functional magnetic resonance. Results: Results suggest a signifi cant positive correlation between cognitive empathy and activation of the bilateral superior medial frontal cortex nodes of the DMN. Contrastingly, a negative correlation was found between emotional empathy and the same brain region. Conclusions: Overall, this data highlights a critical role of the medial cortical regions of the DMN, specifi cally its anterior node, for both cognitive and emotional domains of the empathic process.
- Nodes of the default mode network implicated in the quality of empathic responses: a clinical perspective of the empathic responsePublication . Oliveira-Silva, Patrícia; Maia, Liliana; Coutinho, Joana; Moreno, Ana Filipa; Penalba, Lucia; Frank, Brandon; Soares, José Miguel; Sampaio, Adriana; Gonçalves, Óscar F.The ability to empathize with another person's inner experience is believed to be a central element of our social interactions. Previous research has focused on cognitive (e.g., theory of mind) and emotional (e.g., emotional contagion) empathy, and less on behavioral factors (i.e., the ability to respond empathically). Recent studies suggest that the Default Mode Network (DMN) mediates individual variability in distinct empathy-related behaviors. However, little is known about DMN activity during actual empathic responses, understood in this study as the ability to communicate our understanding of the others’ experience back to them. This study used an empathy response paradigm with 28 participants (22-37 years old) to analyze the relationship between the quality of empathic responses to 14 empathy-eliciting vignettes and patterns of attenuation in the DMN. Overall, the results suggest that high levels of empathic response, are associated with sustained activation of the DMN when compared with lower levels of empathy. Our results demonstrate that the DMN becomes increasingly involved in empathy-related behavior, as our level of commitment to the other's experience increases. This study represents a first attempt to understand the relation between the capacity for responding in a supportive way to others’ needs and the intra-individual variability of the pattern of the DMN attenuation. Here we underline the critical role that the DMN plays in high-level social cognitive processes and corroborate the DMN role in different psychiatric disorders associated with a lack of empathy.
