美國賓夕法尼亞大學Wei Song Ong研究團隊在研究中取得進展。他們提出猴子戰略合作的神經元關聯。該研究於2020年11月23日發表於國際一流學術期刊《自然-神經科學》。
他們記錄了雄猴在玩類似「雞」遊戲過程中的神經活動,在該過程中中,他們決定合作還是不合作以獲得不同大小的獎勵。中上顳溝(mSTS)中的神經元(先前涉及社會知覺)傳達了重要的戰略信息,包括收益、另一位參與者的意圖、獎勵結果和對另一位參與者的預測。
此外,mSTS神經元的一個亞群選擇性地發出信號,表明合作獲得的獎勵。前扣帶回中的神經元先前涉及替代性強化和同理心,但攜帶的有關戰略變量(尤其是合作性獎勵)的信息較少。戰略信號無法還原為有關其他參與者或運動意外事件的感知信息。
這些結果表明,計算其他參與者模型的能力根源於靈長類動物的戰略性社會行為,並且前扣帶回和mSTS支持這些計算。

Abstract: We recorded neural activity in male monkeys playing a variant of the game 『chicken』 in which they made decisions to cooperate or not cooperate to obtain rewards of different sizes. Neurons in the middle superior temporal sulcus (mSTS)—previously implicated in social perception—signaled strategic information, including payoffs, intentions of the other player, reward outcomes and predictions about the other player. Moreover, a subpopulation of mSTS neurons selectively signaled cooperatively obtained rewards. Neurons in the anterior cingulate gyrus, previously implicated in vicarious reinforcement and empathy, carried less information about strategic variables, especially cooperative reward. Strategic signals were not reducible to perceptual information about the other player or motor contingencies. These findings suggest that the capacity to compute models of other agents has deep roots in the strategic social behavior of primates and that the anterior cingulate gyrus and the mSTS support these computations.
