静息状态的EEG信号经历快速转换过程(RTP),该过程粘合否则静止的时期。我们研究了RTPs在空间和时间上的分形特性,支持了大脑工作在临界状态的假设。我们讨论了集体兴奋的全球间歇性动力学是如何与心理状态,即非约束非任务导向的心理活动。
Resting-state EEG signals undergo rapid transition processes (RTPs) that glue otherwise stationary epochs. We study the fractal properties of RTPs in space and time, supporting the hypothesis that the brain works at a critical state. We discuss how the global intermittent dynamics of collective excitations is linked to mentation, namely non-constrained non-task-oriented mental activity.
