误差相关负波(ERN)是通过对theta频段的脑电振荡进行相位重置而产生的。本研究评估了一组分析方法，这些方法最近被用来为这一假设提供证据。为了评估这些方法，我们将它们分别应用于两个模拟数据集：一个集包括theta相位重置，另一个集包括嵌入脑电噪声中的相位峰。结果表明，这些分析方法不能有效区分两个模拟数据集。具体地说，从相位峰值构建的模拟数据集虽然不包含正在进行的EEG活动的同步，但展示了先前被解释为支持ERN的同步振荡帐户的属性。这些发现表明，所提出的分析方法不能提供明确的证据，证明ERN是由正在进行的振荡的相位重置产生的。
It has been proposed that the error-related negativity (ERN) is generated by phase resetting of theta-band EEG oscillations. The present research evaluates a set of analysis methods that have recently been used to provide evidence for this hypothesis. To evaluate these methods, we apply each of them to two simulated data sets: one set that includes theta phase resetting and a second that comprises phasic peaks embedded in EEG noise. The results indicate that the analysis methods do not effectively distinguish between the two simulated data sets. In particular, the simulated data set constructed from phasic peaks, though containing no synchronization of ongoing EEG activity, demonstrates properties previously interpreted as supporting the synchronized oscillation account of the ERN. These findings suggest that the proposed analysis methods cannot provide unambiguous evidence that the ERN is generated by phase resetting of ongoing oscillations.
