The dorsal frontoparietal network (dFPN) of the human brain assumes a puzzling variety of functions, including motor planning and imagery, mental rotation, spatial attention, and working memory. How can a single network engage in such a diversity of roles? We propose that cognitive computations relying on the dFPN can be pinned down to a core function underlying offline motor planning: action emulation. Emulation creates a dynamic representation of abstract movement kinematics, sustains the internal manipulation of this representation, and ensures its maintenance over short time periods. Based on these fundamental characteristics, the dFPN has evolved from a pure motor control network into a domain-general system supporting various cognitive and motor functions.

背侧额顶网络：模拟动作的核心系统

人脑的背侧额顶神经网络 (dFPN) 具有多种令人费解的功能，包括运动规划和意象、心理旋转、空间注意力和工作记忆。一个网络怎么能扮演如此多样化的角色？我们建议依赖 dFPN 的认知计算可以归结为离线运动规划的核心功能：动作仿真。仿真创建抽象运动运动学的动态表示，维持该表示的内部操作，并确保其在短时间内维护。基于这些基本特征，dFPN 已经从纯运动控制网络演变为支持各种认知和运动功能的域通用系统。
