| Abstract(in English) | fNIRS(functional near infrared spectroscopy) is regarded as a technique to estimate the activity of a human brain indirectly by measuring a hemoglobin density dynamics of the cortex caused by activity of a brain. An inevitable noise caused by various factors is to be included in a signal measured by fNIRS. Usually, hemoglobin density in the human brain cortex is found to change slowly in time. Then, in general, the high frequency components was removed through a simple low pass filter and moving average scheme with temporal average procedure. However, we may expect the possibility the hemoglobin density dynamics measured by fNIRS possesses chaotic properties. From this respect, in this report, we shall examine a signal measured by fNIRS whether it is chaotic or not. From the present analyses, in conclusion, it is shown that chaotic properties may be detected in the signal measured by fNIRS, which may be related to those of ECG etc. |
