The capacity to evaluate the outcomes of our actions is fundamental for adapting and optimizing behavior and depends on an action-monitoring system that assesses ongoing actions and detects errors. The neuronal network underlying this executive function, classically attributed to the rostral cingulate zone, is poorly characterized in humans, owing to the limited number of direct neurophysiological data. Using intracerebral recordings, we show that the leading role is played by the supplementary motor area (SMA), which rapidly evaluates successful and erroneous actions. The rostral part of medial prefrontal cortex, driven by the SMA, was activated later and exclusively in the case of errors. This suggests a hierarchical organization of the different frontal regions involved in implementation of action monitoring and error processing.
评估我们行为结果的能力对于适应和优化行为至关重要，这取决于一个能够评估正在进行的行为并检测错误的行为监测系统。由于直接的神经生理学数据有限，因此人类中这种执行功能的神经网络（经典上归因于额前扣带区）特征描述得很差。使用脑内记录，我们表明，主导作用是由补充运动区（SMA）发挥的，它可以快速评估成功和错误的动作。由 SMA 驱动的内侧前额叶皮质的前部部分较晚且仅在出现错误的情况下被激活。这表明不同额前区域在实施行为监测和错误处理中存在层次结构组织。
