We evaluate the capability of reconstructing Fokker-Planck equations for an improved characterization of electroencephalographic (EEG) recordings from epilepsy patients. We derive stochastic qualifiers of brain dynamics that are based on specific characteristics of the Kramers-Moyal coefficients estimated from the EEG. Analyzing long-lasting multichannel EEG recordings from eight patients suffering from focal epilepsies we show that particularly the stochastic part of the dynamics can yield valuable information for diagnostic purposes.
我们评估了重建福克 - 普朗克方程的能力，以更好地表征癫痫患者的脑电图（EEG）记录。我们推导了基于从脑电图估计的克莱默斯 - 莫亚尔系数的特定特征的脑动力学随机限定符。通过分析八名患有局灶性癫痫患者的长期多通道脑电图记录，我们表明，特别是动力学的随机部分可以为诊断目的提供有价值的信息。
