집중명상과 마음챙김명상이 뇌의 주의체계에 미치는 영향
Effect of Concentration and Mindfulness Meditation on Attention Systems of Brain
초록
본 연구는 집중명상과 마음챙김명상이 뇌의 주의체계(배측체계와 복측체계)에 미치는 영향을 알아보기 위해 수행되었다. 명상 수련경험이 평균 4.0년인 9명의 실험참가자들을 대상으로 했다. 뇌의 주의체계의 활성화를 측정하기 위해 EEG를 기록하고 이것을 sLORETA 분석을 하였다. 먼저, 기저선 2분을 측정하고 각각 5분간 집중명상과 마음챙김명상을 수행하는 동안 EEG를 기록하였다. 명상의 순서는 균형을 맞추었다. 연구의 결과에서 집중명상과 마음챙김명상 모두 대뇌의 활성화를 감소시켰다. 집중명상과 마음챙김명상과 각 기저선과의 차이에서 확인된 것은 마음챙김명상은 상대적으로 전측 대상회와 하전두회 그리고 안와전두회가 활성화되는 것을 확인하였고 집중명상의 경우는 안와전두회만 상대적으로 활성화되는 것을 확인하였다. 이 결과가 갖는 의미는 논의에서 논했다.

Abstract
The purpose of this research was to investigate the effect of concentration meditation and mindfulness meditation on attention systems of the brain. Subjects were 9 male and female experts of meditation, who trained for the mean of 4.0 years. EEG was recorded during a 5min concentration meditation and mindfulness meditation, with a 2min baseline, individually. In sLORETA analysis, both meditations suppressed the brain activity. Mindfulness meditation was relatively activated in the anterior cingulate, inferior frontal gyrus, and orbitofrontal cortex, when compared to that of the other areas of the brain. However, concentration meditation was relatively activated only in the orbitofrontal cortex compared to the of the areas of the brain. Implication for this result was discussed in the final section.
