人类脑磁图时间序列的弛豫和相空间奇异性作为光敏性癫痫的指标
Relaxation and phase space singularities in time series of human magnetoencephalograms as indicator of photosensitive epilepsy
摘要：
为了分析波动和弛豫效应对人脑功能的重要作用，我们研究了支持神经磁脑反应（脑磁图，MEG）信息特征的一些统计量词。不同颜色组合的闪烁刺激的信号已经从一组对照受试者中获得，然后将其与患有光敏性癫痫（PSE）的患者的信号进行对比。我们发现，相云的特定分层的存在和相应的非平衡动力学的混沌行为的信号在不同的区域中的患者伴随的松弛奇异性提供可能的指标，负责PSE的外观的区域。
英文摘要：
To analyze the crucial role of fluctuation and relaxation effects for the function of the human brain we studied some statistical quantifiers that support the information characteristics of neuromagnetic brain responses (magnetoencephalogram, MEG). The signals to a flickering stimulus of different color combinations have been obtained from a group of control subjects which is then contrasted with those of a patient suffering photosensitive epilepsy (PSE). We found that the existence of the specific stratification of the phase clouds and the concomitant relaxation singularities of the corresponding nonequilibrium dynamics of the chaotic behavior of the signals in separate areas in a patient provide likely indicators for the zones which are responsible for the appearance of PSE.
