摘要： A response period is determined arbitrarily. A satisfactory detecting ability may not be provided because of an artifact or the like contained in a signal. Therefore, an effective detection method and an effective display method of presenting results of detection must be developed. A series of tasks (stimuli) or a selected measurement signal is used as a reference signal, and a phase difference of any other measurement signal from the reference signal is calculated. The synchronousness of the phase of the measurement signal with the phase of the reference signal is numerically expressed. The thus obtained numerical value is statistically processed in order to numerically express a degree of reliability. Thus, a brain activity or a functional connectivity is visualized.

摘要： A typical task assigned for measuring a brain activity signal lasts from 10 to 30 seconds. The frequency band of the Mayer wave noise signal is very close to the frequency bands of brain activity signals, a result, it is difficult to reduce the Mayer wave noise signal using a bandpass filter or a bandcut filter. Light irradiating units and light detecting units for detecting the emitted light that has been passed through or reflected within the tissue are provided. A biological signal measuring unit measures at least one of the pulsation, breathing, blood pressure, and temperature. The relationship between an optical signal obtained by the light detecting unit and a biological signal using non-linear analysis; and a computation for separating the biological noise signal from the optical signal on the basis of the obtained relationship.
