Playing "Go," a board game created in China more than 2,500 years ago, improves cerebral function, sources reported, Sunday.

The discovery was confirmed by a research team led by Korean professor Kwon Jun-su from the Neuropsychiatry Department of Seoul National University Hospital.

Kwon's study was helped by 17 professional Go players (mean age 17, average years of playing 12.4) and 16 ordinary people having the same mean age.

After both groups took sufficient rest, their brains were studied using Functional Magnetic Resonance Imaging (fMRI). The imaging system shows brain cell activity rates by detecting changes in the number of hemoglobin which carries oxygen throughout cerebral blood flow.

The result found that the professional Go players' brains had control of emotional and intuitive assessments that were more linked to each other, allowing them to perform a task in a more synchronized fashion.

Such a performance boost was derived from a more active "amygdale" and "orbitofrontal cortex," parts of the brain responsible for emotional and intuitive cognition, as well as the "parietal lobe" that calculates spatial data.

"The recent discovery proposes a new way of looking at human brains," said Prof. Kwon. "It supports the already existing hypothesis that repetitive, long-term tasks alter the brain's functional foundation."

Kwon's study was published in the October edition of "Frontiers in Human Neuroscience."


뇌 기능 향상 '바둑' 한몫 한다

'바둑'이 두뇌의 기능 발달에 큰 영향을 미친다는 연구 결과가 국내 연구진에 의해 다시 한 번 확인됐다. 

5일 서울대병원 정신건강의학과 권준수 교수 연구팀에 따르면 장기간의 바둑훈련은 두뇌 기능을 발달시킨다. 

이번 연구는 평균 12.4년 바둑을 훈련한 바둑 전문가를 대상으로 뇌의 기능이 일반인들과 어떠한 차이가 있는지를 규명 하고자 실시했다. 

이번 연구에서는 17명의 바둑 전문가(비교군, 평균 연령 17세, 남: 14명, 여: 3명)와 16명의 일반인(대조군, 평균 연령 17세, 남: 12명, 여: 4명)을 대상으로 MRI 영상의 하나인 fMRI(기능적 자기 공명 영상)를 촬영했다. 

그 결과 비교군이 대조군에 비해 정서적 처리와 직관적 판단에 관여하는 편도체와 안와전두엽 부위의 기능이 활성화됐으며 공간적 위치정보를 처리하는 두정엽 부위에서도 같은 현상이 관찰됐다. 

즉 바둑 전문가는 일반인에 비해 정서적 처리, 직관적 판단을 처리하는 뇌 부위들이 서로 잘 연결돼 하나의 자극에 일련의 합목적적인 역할을 잘 수행할 수 있음을 의미한다. 

권준수 교수는 '이 발견은 인간의 뇌기능을 이해하는데 새로운 시각을 제공했다는 평가를 받고 있으며 장기간 반복된 수련을 통해 뇌기능이 변화할 수 있다는 기존 가설을 지지해주는 것으로 평가된다'고 말했다.
