Abstract:
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.
摘要:
语言处理过程中的脑电图(EEG)和脑磁图(MEG)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。为了纵向使用EEG和MEG,在健康个体中,结果测量应跨时间保持一致。因此,本研究对健康成年人在语言范式中引起的EEG和MEG测量的重测可靠性进行了综述。PubMed,根据特定的资格标准,搜索了WebofScience和Embase的相关文章。总的来说,这篇文献综述包括11篇文章。系统认为P1、N1和P2的重测可靠性令人满意,而对于事件相关的电位/场,发现的变化更大。语言处理期间EEG和MEG测量的受试者内一致性可以受到多个变量的影响,例如刺激呈现模式,离线参考选择和任务期间所需的认知资源量。最后,对于健康年轻人在语言范例中引起的EEG和MEG测量的纵向使用,大多数可用结果都是有利的。鉴于这些技术在失语症患者中的运用,未来的研究应该关注相同的发现是否适用于不同的年龄组.
