高级大脑功能的一个标志是能够根据内部和外部线索快速灵活地调整行为反应。在这里，我们研究了允许决策和行动及时灵活展开的计算原理。我们采用动态系统的视角，并概述了如何通过操纵输入和初始条件来实现此类系统的时间灵活性。然后，我们回顾了非人类灵长类动物实验中支持这一解释的证据。最后，我们探讨了动力系统视角作为解决与运动时间控制以及学习和序列生成领域相关的开放性问题的通用框架的更广泛的效用和局限性。
A hallmark of higher brain function is the ability to rapidly and flexibly adjust behavioral responses based on internal and external cues. Here, we examine the computational principles that allow decisions and actions to unfold flexibly in time. We adopt a dynamical systems perspective and outline how temporal flexibility in such a system can be achieved through manipulations of inputs and initial conditions. We then review evidence from experiments in nonhuman primates that support this interpretation. Finally, we explore the broader utility and limitations of the dynamical systems perspective as a general framework for addressing open questions related to the temporal control of movements, as well as in the domains of learning and sequence generation.
