    "abstract": "The fluctuation properties of the human electroencephalogram (EEG) time\nseries are studied using detrended fluctuation analysis. For all 128 channels\nin each of 18 subjects studied, it is found that the standard deviation of the\nfluctuations exhibits scaling behaviors in two regions. Topographical plots of\nthe scaling exponents reveal the spatial structure of the nonlinear electrical\nactivities recorded on the scalp. Moment analyses are performed to extract the\ngross features of all the scaling exponents. The correlation between the two\nscaling exponents in each channel is also examined. It is found that two\nindices can characterize the overall properties of the fluctuation behaviors of\nthe brain dynamics for every subject and that they vary widely across the\nsubjects.",
