  • Objectives: In this functional magnetic resonance imaging study, we aimed to investigate the differences in brain activation between individuals with autism spectrum disorder (ASD) and typically developing (TD) individuals during perspective taking. We also examined the association between brain activation and empathic and interoceptive abilities. Methods: During scanning, participants from the ASD (n=17) and TD (n=22) groups were shown pain stimuli and asked to rate the level of the observed pain from both self- and other-perspectives. Empathic abilities, including perspective taking, were measured using an empathic questionnaire, and three dimensions of interoception were assessed: interoceptive accuracy, interoceptive sensibility, and interoceptive trait prediction errors. Results: During self-perspective taking, the ASD group exhibited greater activation in the left precuneus than the TD group. During other-perspective taking, relative hyperactivation extended to areas including the right precuneus, right superior frontal gyrus, left caudate nucleus, and left amygdala. Brain activation levels in the right superior frontal gyrus while taking other-perspective were negatively correlated with interoceptive accuracy, and those in the left caudate were negatively correlated with perspective taking ability in the ASD group. Conclusion: Individuals with ASD show atypical brain activation during perspective taking. Notably, their brain regions associated with stress reactions and escape responses are overactivated when taking other-perspective. This overactivity is related to poor interoceptive accuracy, suggesting that individuals with ASD may experience difficulties with the self-other distinction or atypical embodiment when considering another person's perspective.

  • 목적 : 본 연구의 목적은 내수용 감각(interoception)과 감각처리, 그리고 자율신경계의 균형을 반영하는 심박변이도와의 관계를 알아보는 것이다. 연구방법 : 젊은 성인을 대상으로 청소년/성인 감각프로파일(Adolescent/Adult Sensory Profile; AASP)과 다차원 내수용 자각 척도(Multidimensional Assessment of Interoceptive Awareness; MAIA)를 사용하여 감각처리와 내수용 감각을 평가하였다. 심박은 안정상태 심전도로 기록되었고, 심전도에서 심박표준편차(Standard Deviation of Normal to Normal interval; SDNN)를 추출하였다. AASP 감각영역과 MAIA 하위척도 간 상관을 분석하였고, 높은 SDNN과 낮은 SDNN 집단 간의 감각처리 및 내수용 감각의 차이를 비교하였다. 결과 : AASP 촉각 영역이 MAIA 하위척도와 상대적으로 강한 상관을 나타내었다. AASP 촉각 영역의 점수가 높을수록 MAIA 걱정하지 않음과 주의 조절 점수가 낮은 반면, 정서자각 점수는 높았다. 높은 SDNN 집단은 낮은 SDNN 집단과 비교하였을 때 내수용 감각이 높은 경향성을 나타냈다. 결론 : 본 연구는 촉각 처리와 내수용 감각의 관련성을 확인하였으며, 심박변이도가 높은 그룹은 내수용 자각이 높은 경향성이 있음을 제시하였다. 본 연구는 최근 작업치료와 감각통합에서 강조되는 내수용 감각에 대한 정보를 제공하고, 감각통합의 신경과학적 기전에 대한 이해를 심화시킨다.
