人类合作行为的神经生物基础及脑模型

已有的脑成像研究表明,个体在社会博弈中的合作决策主要激活与认知控制、社会认知以及奖励加工有关的三类大脑神经网络.首先对上述三类大脑系统的功能及其相应的大脑结构和神经回路进行阐述,并对相关的脑成像研究进行回顾.对激素水平的研究发现,催产素能通过增加人们之间的信任来促进合作.在此基础上,介绍新近提出的关于合作的脑机制模型,最后指出这一领域已有研究存在的一些问题以及未来的研究方向.

Neural biological basis and brain models of human cooperative behaviors

Researches have investigated the neural mechanism of cooperative behavior, and made some progresses in this field. Existing studies in neuroeconomics have revealed that three brain systems are consistently recruited when people face social dilemmas. These are the neural networks dedicated to cognitive control, social cognition, and processing reward. The present review will introduce the involving brain structure of these three brain systems in detail, and overview relative brain imaging studies. The oxytocin system is involved in human social behavior and social cognition such as attachment, emotion recognition and mentalizing. The oxytocin system is involved in human social behavior and social cognition such as cooperative. Finally, we point some problems about current brain imaging research on cooperative behavior, and give some possible directions for future research.
