Electroencephalographic (EEG) and magnetoencephalographic (MEG) recordings during language processing can provide relevant insights on neuroplasticity in clinical populations (including patients with aphasia). To use EEG and MEG in a longitudinal way, the outcome measures should be consistent across time in healthy individuals. Therefore, the current study provides a review on the test-retest reliability of EEG and MEG measures elicited during language paradigms in healthy adults. PubMed, Web of Science and Embase were searched for relevant articles based on specific eligibility criteria. In total, 11 articles were included in this literature review. The test-retest reliability of the P1, N1 and P2 is systematically considered to be satisfactory, whereas findings are more variable for event-related potentials/fields occurring later in time. The within subject consistency of EEG and MEG measures during language processing can be influenced by multiple variables such as the stimulus presentation mode, the offline reference choice and the required amount of cognitive resources during the task. To conclude, most of the available results are favourable regarding the longitudinal use of EEG and MEG measures elicited during language paradigms in healthy young individuals. In view to the use of these techniques in patients with aphasia, future research should focus on whether the same findings apply to different age groups.
脑电图 (EEG) 和脑磁图 (MEG) 在语言处理过程中的记录可以为临床人群 (包括失语症患者) 的神经可塑性提供相关见解。为了以纵向方式使用 EEG 和 MEG，健康个体的测量结果应该在整个时间内保持一致。因此，本研究综述了健康成年人在语言范式中诱发的 EEG 和 MEG 测量的重测信度。根据特定的入选标准，在 PubMed、Web of Science 和 Embase 上搜索了相关文章。共有 11 篇文章纳入本文献综述。P1、N1 和 P2 的重测信度被系统地认为是令人满意的，而对于在时间上发生较晚的事件相关电位/场的发现则更为多变。语言处理过程中 EEG 和 MEG 测量的个体内一致性可能会受到多种变量的影响，例如刺激呈现模式、离线参考选择以及任务期间所需的认知资源量。总之，关于在健康年轻人中使用语言范式诱发的 EEG 和 MEG 测量的纵向使用，大多数现有结果都是有利的。考虑到这些技术在失语症患者中的应用，未来的研究应重点关注这些发现是否适用于不同的年龄组。
