Goal-directed behavior seems to unfold effortlessly, but everyday experience tells us that goal-directed acting can become complicated when confronted with distracting information. Yet, the neural underpinnings of how distracting information affects response selection is still contentious, especially when taking the stance of theoretical frameworks on perception-action integration processes. We show that particularly theta band activity in a ventral stream-parietal network plays a key role in managing distracting information during response selection. While our findings demonstrate bidirectional interactions between these regions, they are consistent with the idea that theta-related communication may support the integration of distracting information across hierarchical processing levels. A decisive factor modulating this dynamic is the timing of distractor and response relevant information. It determines the patterning of cortical activity and how the information transfer between cortical regions is organized. The findings highlight the critical role of theta activity in the directed transfer of information between cortical regions for how distractions influence response selection, thereby offering new insights into the neural basis of perception-action integration.
目标导向行为似乎能轻松展开,但日常经验告诉我们,当面对干扰信息时,目标导向行为可能会变得复杂。然而,关于干扰信息如何影响反应选择的神经基础仍存在争议,尤其是从感知 - 行动整合过程的理论框架角度来看。我们表明,腹侧流 - 顶叶网络中特别是theta频段活动在反应选择过程中管理干扰信息方面起着关键作用。虽然我们的研究结果表明这些区域之间存在双向相互作用,但它们与theta相关通信可能支持跨层次处理水平整合干扰信息的观点一致。调节这种动态的一个决定性因素是干扰物和与反应相关信息的时间。它决定了皮层活动的模式以及皮层区域之间信息传递的组织方式。这些发现突出了theta活动在干扰如何影响反应选择时皮层区域间信息定向传递中的关键作用,从而为感知 - 行动整合的神经基础提供了新的见解。
