评估我们行动结果的能力是适应和优化行为的基础，并依赖于评估正在进行的行动和发现错误的行动监测系统。这种执行功能的神经元网络，传统上归因于喙扣带区，是穷人的特点，在人类中，由于数量有限的直接神经生理数据。使用脑内记录，我们表明，发挥主导作用的补充运动区（SMA），迅速评估成功和错误的行动。内侧前额叶皮层的吻侧部分，由SMA驱动，被激活后，专门在错误的情况下。这表明，在执行行动监测和错误处理所涉及的不同额叶区域的层次组织。
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.
