헛디딤 탐지의 신경 상관 : 기능적 자기공명 영상 연구 = Neural Correlates of Faux Pas Detection : An fMRI Study

국문 초록 (Abstract)

본 연구는 마음이론 능력 측정 과제의 하나인 헛디딤 탐지를 수행하는데 관여하는 신경상관 영역을 확인하려는 것이었다. 기능적 자기공명영상 기법을 이용하여 헛디딤 이야기 문장과 헛디딤을 포함하지 않는 통제 이야기 문장을 제시하였을 때 나타나는 뇌 활성화 영역을 비교하였다. 양 반구의 상전두회(BA 6/9)와 설전소엽(BA 7), 좌반구의 내전두회(BA 9), 상측두회(BA 38), 하측두회(BA 20)와 우반구의 하두정소엽(BA 40), 중심후회(BA 1), 설회(BA 18), 횡전두회(BA 41) 등의 영역에서 활성화가 나타났다. 헛디딤 탐지를 하는 동안 안와전두피질과 편도의 활성화는 나타나지 않았다. 이런 결과는 마음이론과 관련된 뇌 활성화는 과제가 이끌어내는 마음상태의 유형에 달려있음을 시사한다.

The aim of this study was to identify neural correlates underlying the detection of faux pas, a test of theory of mind (ToM), in Korean healthy adults. Using functional magnetic resonance imaging, we compared the brain activities associated with faux pas stories and the activities associated with control stories. Faux pas stories compared with the control stories produced activations bilaterally in the superior frontal gyrus (BA 9) and in the precuneus (BA 7). The left medial frontal gyrus (BA 9), the left superior temporal gyrus (BA 38), the left inferior temporal gyrus (BA 20) and the right inferior parietal lobule (BA 40), the right postcentral gyrus (BA 1), the right lingual gyrus (BA 18), the right transverse temporal gyrus (BA 41) were also activated. The orbitofrontal cortex and the amygdala were not found to be involved in the detection of faux pas. This result suggests that brain activations associated with ToM are dependent on the type of mental state drawn by the task.
