摘要:

脑连接可以通过对脑电图(EEG)数据进行大量分析来估计。然而,在连接方法的实现中存在大量的异质性。连接性测量、数据收集或数据预处理概念化中的异质性可能与测量稳健性的可变性相关。虽然很难比较使用不同EEG连通性测量的研究结果,但处理和报告的标准化可能会促进这项任务。我们讨论了如何因素,如参考,历元长度和数量,控制量传导,伪影去除,和多重比较的统计控制影响EEG连接估计连接措施,以及可以做些什么来控制与这些因素相关的潜在混淆。根据以往文献报道的结果,本文提出了建议和一种新的检查表开发的质量评估脑电图连接的研究。这份清单及其建议是为了提请注意可能影响连通性估计的因素和需要在未来研究中改进的因素。标准化的程序和EEG连接的报告可能会导致EEG连接的研究,使更多的综合性和可比性,尽管在方法的基础连接估计的变化。

英文摘要:

Brain connectivity can be estimated through a wide number of analyses applied to electroencephalographic (EEG) data. However, substantial heterogeneity in the implementation of connectivity methods exist. Heterogeneity in conceptualization of connectivity measures, data collection, or data pre-processing may be associated with variability in robustness of measurement. While it is difficult to compare the results of studies using different EEG connectivity measures, standardization of processing and reporting may facilitate the task. We discuss how factors such as referencing, epoch length and number, controls for volume conduction, artefact removal, and statistical control of multiple comparisons influence the EEG connectivity estimate for connectivity measures, and what can be done to control for potential confounds associated with these factors. Based on the results reported in previous literature, this article presents recommendations and a novel checklist developed for quality assessment of EEG connectivity studies. This checklist and its recommendations are made in an effort to draw attention to factors that may influence connectivity estimates and factors that need to be improved in future research. Standardization of procedures and reporting in EEG connectivity may lead to EEG connectivity studies to be made more synthesisable and comparable despite variations in the methodology underlying connectivity estimates.
