已有大量文献证明，人类大脑中解剖学上独立的注意力网络在功能上相互作用以实现目标导向行为。通过将涉及定向网络的空间返回抑制（IOR）与一些执行功能任务（例如，Stroop和flanker任务），研究人员一致发现，与未提示位置相比，提示位置的干扰效应显著降低，表明两个注意网络之间存在功能性相互作用。然而，一个独特的，但一致的效果时，观察到空间IOR与西蒙效应相结合：西蒙效应是显着更大的线索比非线索的位置。为了探讨这种现象背后的神经基板，我们正交结合空间IOR与西蒙效应在本事件相关的功能磁共振成像研究。我们的行为数据重复了以前的结果，在线索位置显示更大的西蒙效应。在神经元水平上，我们发现空间IOR和Simon效应在双侧后顶叶皮层（PPC）有共同的空间表征系统，空间IOR特异性激活双侧上级顶叶皮层，Simon效应特异性激活双侧中额叶皮层。此外，左中央前回参与了空间IOR和西蒙效应之间的神经相互作用，在“线索一致”条件下显示出显着较高的神经活动。综上所述，我们的研究结果表明，由于PPC中共享的空间表征系统，当空间IOR和Simon效应依赖于相同的空间表征时，反应显着促进，即，在“线索一致”条件下。相应地，感觉运动系统在“线索一致”条件下显著参与，加快了反应，间接导致了线索位置的Simon效应增强。
It has been well documented that the anatomically independent attention networks in the human brain interact functionally to achieve goal-directed behaviors. By combining spatial inhibition of return (IOR) which implicates the orienting network with some executive function tasks (e.g., the Stroop and the flanker tasks) which implicate the executive network, researchers consistently found that the interference effects are significantly reduced at cued compared to uncued locations, indicating the functional interaction between the two attention networks. However, a unique, but consistent effect is observed when spatial IOR is combined with the Simon effect: the Simon effect is significantly larger at the cued than uncued locations. To investigate the neural substrates underlying this phenomenon, we orthogonally combined the spatial IOR with the Simon effect in the present event-related fMRI study. Our behavioral data replicated previous results by showing larger Simon effect at the cued location. At the neural level, we found shared spatial representation system between spatial IOR and the Simon effect in bilateral posterior parietal cortex (PPC); spatial IOR specifically activated bilateral superior parietal cortex while the Simon effect specifically activated bilateral middle frontal cortex. Moreover, left precentral gyrus was involved in the neural interaction between spatial IOR and the Simon effect by showing significantly higher neural activity in the “Cued_Congruent” condition. Taken together, our results suggest that due to the shared spatial representation system in the PPC, responses were significantly facilitated when spatial IOR and the Simon effect relied on the same spatial representations, i.e., in the “Cued_Congruent” condition. Correspondingly, the sensorimotor system was significantly involved in the “Cued_Congruent” condition to fasten the responses, which indirectly resulted in the enhanced Simon effect at the cued location.
