研究了脑电信号在α范围内大尺度、长时间的位相同步行为的动力学特性。我们观察到了动态的相位同步，并提出了潜在的时空有序的证据。间歇性同步持续时间的波动是尺度不变的。此外，用于描述这种行为的指数在不同的正常受试者中是稳定的。这些结果提供了人脑活动自组织的新特征，并为建立其动力学模型提供了定量依据。(C)2002爱思唯尔科学爱尔兰有限公司。保留所有权利。
The dynamical properties of large-scale, long-term phase synchronization behavior in the alpha range of electroence-phalographic signals were investigated. We observed dynamical phase synchronization and presented evidence of an underlying spatiotemporal ordering. Fluctuations in the duration of episodes of intermittent synchrony are scale-invariant. Moreover, the exponent used to describe this behavior is stable across different normal subjects. The results provide a new feature of self-organization in human brain activity and constitute a quantitative basis for modeling its dynamics. (C) 2002 Elsevier Science Ireland Ltd.
