Approach to brain mechanisms of "Sociality"-Roles of the monkey anterior cingulate cortex in the performance of competitive games

点击翻译按钮获取中文摘要

I focused on the anterior cingulate cortex (ACC), which is considered to be important for "Sociality". I recorded neuronal activity from the ACC while a monkey played competitive video shooting games with a rival. We found that differences in (1) competitive/noncompetitive situation, (2) identity or animacy of the rival, and (3) winning/losing of the game were represented at both behavioral and neuronal levels. These findings implicate the importance of ACC for "Sociality".
