Weighted-permutation entropy (WPE) is modified from permutation entropy (PE), which recently has been proposed as a measurement for nonlinear time series. To explore the efficiency of this method and the features of seizure electroencephalogram (EEG) segments, we investigate the application of WPE in the complexity analysis for epileptic seizure detection based on EEG. It is found that the calculated...
In this paper limited penetrable visibility graph (LPVG) approach is introduced to analyze the background electroencephalograph (EEG) activity in Alzheimer's disease (AD) patients. LPVG provides a measure of transforming the time series, i.e., EEG, into complex networks, which has become a research hotspot in the field of cognitive neurodynamics. So in this work, LPVG is chosen as the center method...
This paper adopts the visibility graph to analyze the short time series of fractal Brownian motion (fBm), and examines this method in estimating Hurst exponents. The maximum likelihood estimation is introduced to estimate the power-law index and the statistics to judge the performance of the estimation. In the result, we found that the first minimum of the Kuiper statistic can provide an optimal estimation...
Manual acupuncture(MA), as a mechanical action, can be equivalent to an external stimulus to the neural system. To explore the effect of MA on brain activities, we design an experiment that acupuncture at Zusanli acupoint with four different frequencies to obtain electroencephalograph (EEG) signals. Neural system is a complex nonlinear dynamics system that possesses strong nonlinear characteristic,...
Manual acupuncture (MA), as a mechanical action, can be equivalent to an external stimulus to the neural system. To explore the effect of MA on the information transformation of the brain, we design an experiment that acupuncture at Zusanli acupoint of right leg with four different frequencies to obtain electroencephalograph (EEG) signals. Neural system is a complex nonlinear dynamics system that...
