  • 1606 Extracting neuronal activity related components from cerebral hemodynamic changes, KATURA Takusige, SATO Hiroki, MAKI Atsushi, TANAKA Naoki, Conference on Information, Intelligence and Precision Equipment : IIP, 2008,   2008 03 17 , Optical topography (OT) signals measured during an experiment using activation tasks for certain brain functions contain neuronal-activation-induced blood oxygenation changes and also physiological changes. We used independent component analysis (ICA) for separating them, and extracted components related to brain activation without using any hemodynamic models. The analysis procedure has three stages: first, OT signals are separated into independent components (ICs) by using time-delayed decorrelation algorithm. Second, task-related ICs (TR-ICs) are selected from the separated ICs based on their mean inter-trial cross-correlations. Third, the TR-ICs are categorized into two clusters by k-mean clustering method and these are classified into TR activation-related ICs (TR-AICs) and TR noise ICs (TR-NICs). We applied this procedure to analysis of the OT signals obtained from experiments with one-handed finger tapping tasks. In the averaged waveform of TR-AICs, a small overshoot can be seen a few seconds after the onsets of each task and a few seconds after the ends, while the averaged waveform of TR-NICs show an N-shaped pattern.

SSE, 97, (242) 1 - 6,   1997 08 29 , Recent statistical analyses of large set of traffic measurements in high-speed networks have provided convincing evidence for the presence of features in actual networks such as burstness, long-range dependence and selfsimilarity. In this report we demonstrate that these characteristics of the traffic can be modeled successfully by using a class of chaotic maps. We further study the models based on these chaotic maps for simple traffic processes, and show the effectiveness of the models.

Nonlinear problems, 95, (201) 25 - 32,   1995 08 01 , We propose a method for distnction of chaos from random fractal sequences(RFS), one of strongly auto-correlated noise. RFS is a non-stationary noise whose power spectrum has the form f^<-α>(1<α<3) and it has been difficult to discriminate from chaos by the previous methods. In the proposed method, time series is predicted both forward and backward, and the accuracy of the two types of prediction is compared. We show that if the time series chaotic and originates from a dissipative system, the accuracy is higher for the forward prediction than for the backward prediction, whereas the accuracy is the same if the time series is a random fractal sequence. The method can be also applied to distinguishing between stationary noise and chaos.
