患者;奖励在增强反应抑制中起着至关重要的作用。虽然一般认为反应抑制过程包括注意捕获和动作停止，但尚不清楚这是否反映了奖励对反应抑制的直接影响，还是通过注意捕获的间接中介。在这里，我们采用了一个修改后的停止信号任务（SST），将这两个认知要素分开，包括一个继续信号，该信号需要与围棋试验中相同的运动反应，但也需要注意提示，就像停止试验一样。我们首先在停止和继续试验中证实了右额下回（IFG）的参与，这两种试验都需要对任务相关线索的注意捕获，但其中只有一种需要运动抑制。通过停止试验和继续试验的对比，辅助前运动区（pre - SMA）被特异性激活。结果表明，IFG在意外刺激下的注意捕获中起重要作用，而前SMA负责直接控制运动抑制。奖励可以改善SST的行为表现，而且奖励还会引起IFG活动的增加。此外，这种有利的奖励效应与前扣带皮层和IFG之间的连通性增强有关。这些结果表明，奖励促进效应对反应抑制的影响是间接的，通过注意加工的改变而发生。目前的数据证实了IFG和前SMA在反应抑制中的特定功能，并提供了直接的证据，证明奖励可以增加IFG中与注意捕获相关的激活，从而提高反应抑制的表现。
&NA; Reward plays a crucial role in enhancing response inhibition. While it is generally assumed that the process of response inhibition involves attentional capture and the stopping of action, it is unclear whether this reflects a direct impact of reward on response inhibition or rather an indirect mediation via attentional capture. Here, we employed a revised stop‐signal task (SST) that separated these two cognitive elements, by including a continue signal that required the same motor response as in go trials, but also attention to a cue, as in stop trials. We first confirmed the engagement of the right inferior frontal gyrus (IFG) during stop and continue trials, both of which required the attentional capture of the task‐relevant cue, but only one of which required motor inhibition. The pre‐supplementary motor area (pre‐SMA) was specifically activated by the contrast of the stop trials with the continue trials. The results indicated that the IFG played an important role in attentional capture by unexpected stimuli, while the pre‐SMA was responsible for the direct control of motor inhibition. Behavioral performance of the SST was improved by reward, and moreover, reward induced an increase in IFG activity. In addition, this advantageous reward effect was associated with enhanced connectivity between the anterior cingulate cortex and the IFG. These results indicated that the reward facilitation effect on response inhibition was indirect, occurring via a change in attentional processing. The present data confirm the specific function of the IFG and pre‐SMA in response inhibition and provide straightforward evidence that reward can increase attentional capture‐related activation in the IFG, which in turn improves the performance of response inhibition.
