表现监测的主要神经生理学原理尚不清楚。错误检测神经系统是否参与行为控制和适应是当前认知神经科学中的一个争论。这样的系统应该产生特定于错误的信号，但它们的存在受到了观察的质疑，即正确和不正确的反应可能会引发类似的神经电势。应用一种基于事件相关大脑电位时频分解的新方法，从人类经典的错误相关消极性（Ne）和正确反应相关消极性（Nc）中提取隐藏的子成分。仅针对 Ne 揭示了来自 delta（1.5-3.5 Hz）频带的独特错误特定子组件，该子组件与整体性能监控级别的错误检测相关。来自 theta 频段 (4-8 Hz) 的子组件与运动响应执行相关，但该子组件还区分了错误与正确反应，指示运动监控级别的错误检测。事实证明，大脑中确实存在特定于错误的信号。更重要的是，错误检测可能发生在不同行为控制级别并行运行的多个功能系统中。 (C) 2004 Elsevier Inc. 保留所有权利。
Major neurophysiological principles of performance monitoring are not precisely known. It is a current debate in cognitive neuroscience if an error-detection neural system is involved in behavioral control and adaptation. Such a system should generate error-specific signals, but their existence is questioned by observations that correct and incorrect reactions may elicit similar neuroelectric potentials. A new approach based on a time-frequency decomposition of event-related brain potentials was applied to extract covert sub-components from the classical error-related negativity (Ne) and correct-response-related negativity (Nc) in humans. A unique error-specific sub-component from the delta (1.5-3.5 Hz) frequency band was revealed only for Ne, which was associated with error detection at the level of overall performance monitoring. A sub-component from the theta frequency band (4-8 Hz) was associated with motor response execution, but this sub-component also differentiated error from correct reactions indicating error detection at the level of movement monitoring. It is demonstrated that error-specific signals do exist in the brain. More importantly, error detection may occur in multiple functional systems operating in parallel at different levels of behavioral control. (C) 2004 Elsevier Inc. All rights reserved.
