Attentional orienting and response inhibition have largely been studied separately. Each has yielded important findings, but controversy remains concerning whether they share any neurocognitive processes. These conflicting findings may originate from two issues: (1) at the cognitive level, attentional orienting and response inhibition are typically studied in isolation; and (2) at the technological level, a single neuroimaging method is typically used to study these processes. This article reviews recent achievements in both spatial and temporal neuroimaging, emphasizing the relationship between attentional orienting and response inhibition. We suggest that coordinated engagement, both top-down and bottom-up, serves as a common neural mechanism underlying these two cognitive processes. In addition, the right ventrolateral prefrontal cortex may play a major role in their harmonious operation.
注意力定向和反应抑制在很大程度上是分别进行研究的。二者均已得出重要研究成果，但关于它们是否共享任何神经认知过程仍存在争议。这些相互矛盾的研究结果可能源于两个问题：（1）在认知层面，注意力定向和反应抑制通常是孤立进行研究的；（2）在技术层面，通常使用单一的神经成像方法来研究这些过程。本文综述了空间和时间神经成像方面的最新成果，重点强调了注意力定向与反应抑制之间的关系。我们认为，自上而下和自下而上的协同参与是这两个认知过程共同的神经机制。此外，右侧腹外侧前额叶皮层可能在它们的协调运作中起主要作用。
