参与认知任务通常涉及执行任务所需的心理资源的配置，从一个任务切换到另一个任务涉及这些资源的重新配置。据信，这种配置和重新配置需要大脑的前额叶皮层来促进参与任务执行的分布式大脑区域的激活，并使其他区域变得不方便。虽然易化和去易化可能发生在任务执行过程中，但我认为它们也可能在任务执行之前启动，并作为任务执行的准备。这一观点来自于对大脑功能的大规模分布式神经认知网络理解，该网络强调大脑中的任务准备和期望（或任务设置）过程以及感知和行动过程。简而言之，它要求区分任务配置过程和任务执行过程。本文提出并讨论了一些证据表明，前额叶皮层的感觉和运动脑区的自上而下的配置，以构建任务集，这种配置取决于自上而下的大脑过程中的β-频率范围内，资源配置可能发生在大脑在任务执行前休息。
Engagement in a cognitive task typically involves configuration of the mental resources needed to perform the task, and switching from one task to another involves the reconfiguration of those resources. It is believed that this configuration and reconfiguration require the prefrontal cortex of the brain to facilitate the activation of distributed brain areas that will be involved in task execution and defacilitate others. Although facilitation and defacilitation may occur during task execution, I consider here that they may also be initiated in advance of, and as preparation for, task execution. This point of view comes from a large-scale, distributed neurocognitive network understanding of brain function that emphasizes processes of task preparation and expectation (or task set) in the brain in addition to processes of perception and action. In short, it requires that a distinction be made between task configuration processes and task execution processes. This paper presents and discusses some convergent lines of evidence suggesting that the prefrontal cortex exerts top-down configuration of sensory and motor brain areas to construct task set, that this configuration depends on top-down brain processes in the beta-frequency range, and that resource configuration may occur when the brain is at rest prior to task execution.
