Abstract：
Recent advances in cognitive neurosciences suggest that intrinsic brain networks dynamics are associated with cognitive functioning. Despite this emerging perspective, limited research exists to validate this hypothesis. This Registered Report aimed to specifically test the relationship between intrinsic brain spatio-temporal dynamics and executive functions. Resting-state EEG microstates were used to assess brain spatio-temporal dynamics, while a comprehensive battery of nine cognitive function tasks was employed to evaluate executive functions in 140 participants. We hypothesized that microstates (class C and D) metrics would correlate with an executive functions composite score. Contrary to expectations, our hypotheses were not supported by the data. We however observed a small, non-significant trend with a negative correlation between microstate D occurrences and executive functions scores (r = -.18, 95% CI [-.33, -.01]) which however did not meet the adjusted threshold for significance. In light of the inconclusive or minor effect sizes observed, the assertion that intrinsic brain networks dynamics - as measured by resting-state EEG microstate metrics - are a reliable signature of executive functioning remains unsupported.
摘要：
认知神经科学的最新进展表明，内在的大脑网络动力学与认知功能有关。尽管有这种新兴的观点，验证这一假设的研究有限。这份注册报告旨在专门测试内在大脑时空动态与执行功能之间的关系。静息状态脑电图微状态用于评估大脑时空动力学，在140名参与者中，采用了9项认知功能任务的综合组评估执行功能。我们假设微状态（C类和D类）指标将与执行功能综合得分相关。与预期相反,数据不支持我们的假设.然而，我们观察到一个小的，微状态D发生与执行功能评分之间呈负相关的非显著趋势(r=-.18,95%CI[-.33,-.01]),但未达到调整后的显著性阈值.根据观察到的不确定或次要影响大小，通过静息状态EEG微状态指标测量的内在脑网络动力学是执行功能的可靠特征的断言仍然没有得到支持.
