Abstract

Intrinsic neural timescales (INT) describe the storage time of neural information in local brain regions, representing the time window for information integration and segregation. Mental task-state electroencephalography (EEG) holds potential clinical value for patients; however, the test-retest reliability of INT remains an open issue. The present study aimed to explore the spatial characteristics of INT and investigate its test-retest reliability by analyzing the data from three mental tasks–subtraction, memory, and music–derived from an open-source EEG database. A classic spatial distribution hierarchy was demonstrated. Our results also revealed that INT had moderate-to-good test-retest reliability. The test-retest reliability of INT in the subtraction task was higher than that in memory and music tasks. Autocorrelation window (ACW)-0 exhibited superior test-retest reliability compared to ACW-50. In summary, our findings provide robust validation of the test-retest reliability of the mental task-state EEG INT from multiple perspectives, thereby facilitating its application in both basic research and clinical settings.

心理任务中的内在神经时间尺度：脑电图测试-重测信度研究。

固有神经时间尺度（INT）描述了神经信息在大脑局部区域的存储时间，代表了信息整合和分离的时间窗口。心理任务状态脑电图（EEG）对患者具有潜在的临床价值；然而，INT的重测可靠性仍然是一个开放的问题。本研究通过分析来自开源脑电图数据库的减法、记忆和音乐三项心理任务数据，探讨脑电信号的空间特征及其重测信度。论证了典型的空间分布层次结构。我们的结果也显示INT具有中等到良好的重测信度。INT在减法任务中的重测信度高于记忆和音乐任务。与ACW-50相比，自相关窗口(ACW)-0表现出更高的重测信度。综上所述，我们的研究结果从多个角度对精神任务状态EEG INT的重测信度进行了稳健的验证，从而促进了其在基础研究和临床环境中的应用。

期刊介绍： Biological Psychology publishes original scientific papers on the biological aspects of psychological states and processes. Biological aspects include electrophysiology and biochemical assessments during psychological experiments as well as biologically induced changes in psychological function. Psychological investigations based on biological theories are also of interest. All aspects of psychological functioning, including psychopathology, are germane. The Journal concentrates on work with human subjects, but may consider work with animal subjects if conceptually related to issues in human biological psychology.
