Abstract(in English) | It is assumed that the mirror neuron system (MNS) plays a fundamental role in understanding actions of other individuals, because it represents observed actions in the observer's brain. Recent studies have shown that the MNS areas (e.g., inferior frontal gyms [IFG]) are related to high-level action understanding such as understanding of goals and intentions. In the current study, we investigated whether the activity in the MNS areas is modulated by the differences in the context of the observed interactions between other individuals. We used movie clips depicting the interaction between two persons: one person (requester) requested the other person to pass one of two objects; the other person (responder) then passed the object that was congruent (congruent condition) or incongruent (incongruent condition) to the request. In the half of the clips, both the requester and the responder appeared on the screen (two condition), and in the other half of the clips, only the responder appeared (one condition). Participants were required to observe the clips from a third-person perspective and to judge whether the responder's actions were congruent or incongruent to the requests. Functional magnetic resonance imaging (fMRI) showed the interaction effect in the brain region including the left IFG (BA45); the magnitude of activation in the incongruent condition was significantly higher than that in the congruent condition, but this difference was found only in the two condition. These results suggest that the left IFG plays an important role in understanding of an action, depending on social contexts. |
