日常操作通常需要快速有效的错误检测和错误纠正。为此，大脑必须尽快积累错误的证据。本研究使用事件相关电位的多变量模式分类技术来跟踪在做出明显反应之前错误相关脑活动的积累。在一个数字侧翼任务中即将发生的错误可以预测后，一个错误的运动反应的启动，类似于90毫秒前的响应执行。运动和顶枕皮层通道是最重要的错误预测，这表明正在进行的感知分析和比较发起和适当的运动程序。与正确试验相比，观察到错误试验的响应力较低，这表明该早期错误信息用于在做出明显响应之前尝试纠正错误。总之，我们的研究结果表明，早期的，自动积累的错误相关的信息，提供输入快速校正过程。(C)2014爱思唯尔有限公司版权所有。
Everyday actions often require fast and efficient error detection and error correction. For this, the brain has to accumulate evidence for errors as soon as it becomes available. This study used multivariate pattern classification techniques for event-related potentials to track the accumulation of error-related brain activity before an overt response was made. Upcoming errors in a digit-flanker task could be predicted after the initiation of an erroneous motor response, similar to 90 ms before response execution. Channels over motor and parieto-occipital cortices were most important for error prediction, suggesting ongoing perceptual analyses and comparisons of initiated and appropriate motor programmes. Lower response force on error trials as compared to correct trials was observed, which indicates that this early error information was used for attempts to correct for errors before the overt response was made. In summary, our results suggest an early, automatic accumulation of error-related information, providing input for fast correction processes. (C) 2014 Elsevier B.V. All rights reserved.
