神经科学和心理学中一个悬而未决的问题是，大脑如何监控表现来调节行为。前扣带回皮质(ACC)位于额叶内侧表面，通过检测错误对操作监控有重要作用。在这项研究中，事件相关功能磁共振成像被用来检测ACC的功能。结果证实，在错误反应过程中，该区域显示出活动。然而，在反应竞争加剧的条件下，在正确反应期间也在同一区域观察到活动。这表明ACC检测的是可能发生错误的条件，而不是错误本身。
An unresolved question in neuroscience and psychology is how the brain monitors performance to regulate behavior. It has been proposed that the anterior cingulate cortex (ACC), on the medial surface of the frontal lobe, contributes to performance monitoring by detecting errors. In this study, event-related functional magnetic resonance imaging was used to examine ACC function. Results confirm that this region shows activity during erroneous responses. However, activity was also observed in the same region during correct responses under conditions of increased response competition. This suggests that the ACC detects conditions under which errors are likely to occur rather than errors themselves.
