跨期决策基于大脑结构与功能连接的神经基础

The Neural Basis for Intertemporal Decision-making:Based on Structural and Functional Connections of the Brain

跨期决策指个体对发生在不同时间点的得益或损失进行的权衡与选择。目前,跨期决策主要有三类神经机制模型:双机制加工模型、单机制加工模型、自我控制模型。本文首先梳理了跨期决策的三个核心网络内部及网络之间的脑结构与功能连接的研究。再从全脑的视角总结了健康与病理性个体的跨期决策的脑结构与功能连接研究的进展。最后,本文提出未来研究应加强跨期决策领域的结构和功能网络的整合,多模态脑数据的融合,以及助推脑结构与功能连接的应用和病理研究。

Intertemporal decision-making involving tradeoffs among costs and benefits occurring at different times-are important and ubiquitous. Recently, with the further research and the development of brain analysis technology, researches emerge to pay attention to brain networks responsible for intertemporal decision-making. The current study firstly combed the brain functional and structural connections of intertemporal decision-making of three core networks-the valuation network, the cognitive control network and the imagery/prospection network. Future researches on intertemporal decision-making can further explore the core brain networks of intertemporal decision-making to sort out how three core networks interact. Secondly, future study needs to enhance the fusion of multimodal brain data research of intertemporal decision-making that will provide a more detailed exploration of the core and other brain regions involved in intertemporal decision-making.In addition, future researches would apply thecore brain networks of intertemporal decision-making to adolescent impulsiveness and neurodevelopmental disorders.
