A critical aspect of cognitive control is the ability to select goal-relevant information in the face of competing distraction. A popular account is that common top-down selection processes underlie the ability to select among competing percepts and memories. We test the degree to which selective attention and memorial selection recruit the same neural resources. We demonstrate that both functions elicit largely overlapping networks within the dorsolateral prefrontal cortex (DLPFC), frontal eye fields (FEF), premotor cortex, and superior parietal lobule (SPL). Despite the close commonalities of selective attention and memorial selection, our results demonstrate that the SPL and FEF show preferential involvement in selective attention, whereas left ventrolateral prefrontal cortex (VLPFC) is uniquely associated with memorial selection. Thus, the two sorts of selection are not identical. We show further that variations in shared selection circuits are associated with differences in behavioral performance, suggesting that economy of control is beneficial to performance.
认知控制的一个关键方面是在面对竞争性干扰时选择与目标相关信息的能力。一种普遍的观点认为，常见的自上而下的选择过程是在相互竞争的感知和记忆中进行选择的能力的基础。我们测试了选择性注意和记忆选择调用相同神经资源的程度。我们证明，这两种功能在背外侧前额叶皮层（DLPFC）、额叶眼区（FEF）、运动前区皮层和顶上小叶（SPL）内引发的神经网络在很大程度上重叠。尽管选择性注意和记忆选择有密切的共性，但我们的结果表明，SPL和FEF在选择性注意中表现出优先参与，而左腹外侧前额叶皮层（VLPFC）则与记忆选择独特相关。因此，这两种选择并不相同。我们进一步表明，共享选择回路的变化与行为表现的差异相关，这表明控制的经济性有利于表现。
