认知神经科学中的一个基本问题是人类大脑如何自我组织来执行任务。这种自组织的多个帐户目前是有影响力的,在本文中,我们调查这些帐户之一。我们开始通过介绍任务控制的心理模型和它预测的几个神经影像信号。然后,我们讨论了这些信号在不同任务中的位置,重点是存在多个控制信号的大脑区域。然后,我们提出的结果来自自发的无任务的功能连接控制相关的区域之间的吻合与控制信号在这些区域中存在的区别,导致一个建议,有至少两个任务控制系统在大脑中。这促使人们考虑这种控制系统是否以及如何在全脑环境中将自己与其他大脑区域区分开来。我们从全脑网络中提出的证据表明,这种区别确实存在,并且控制系统包括人类大脑的一些基本系统级组织元素。最后,我们从全脑网络的观察,可能会建议简约之间的多个帐户的认知控制。
A fundamental question in cognitive neuroscience is how the human brain self-organizes to perform tasks. Multiple accounts of this self-organization are currently influential and in this article we survey one of these accounts. We begin by introducing a psychological model of task control and several neuroimaging signals it predicts. We then discuss where such signals are found across tasks with emphasis on brain regions where multiple control signals are present. We then present results derived from spontaneous task-free functional connectivity between control-related regions that dovetail with distinctions made by control signals present in these regions, leading to a proposal that there are at least two task control systems in the brain. This prompts consideration of whether and how such control systems distinguish themselves from other brain regions in a whole-brain context. We present evidence from whole-brain networks that such distinctions do occur and that control systems comprise some of the basic system-level organizational elements of the human brain. We close with observations from the whole-brain networks that may suggest parsimony between multiple accounts of cognitive control.
