| Abstract(in English) | There is a long-running controversy as to whether brain state variables exhibit chaotic behavior or not. Evidences from an analysis of electroencephalogram (EEG) data and computer simulation imply a chaotic behavior in the brain, however, more efforts are required to search stronger evidences and understand functional implications of the chaotic behavior in the brain. In this study, spontaneous human brain activity was investigated using Near infrared spectroscopy (NIRS), which is a non-invasive brain imaging technique. The correlation dimension and the maximal Lyapunov exponents were estimated from the NIRS time series. The results suggest that high-dimensional chaos may be embedded in some brain region. |
