    "abstract": "We investigate the dynamical properties of electroencephalogram (EEG) signals\nof human in sleep. By using a modified random walk method, We demonstrate that\nthe scale-invariance is embedded in EEG signals after a detrending procedure.\nFurther more, we study the dynamical evolution of probability density function\n(PDF) of the detrended EEG signals by nonextensive statistical modeling. It\ndisplays scale-independent property, which is markedly different from the\nturbulent-like scale-dependent PDF evolution.",
