Unit) Introduction Near infrared spectroscopy (NIRS) calculates hemoglobin parameters, such as change in oxygenated hemoglobin and deoxygenated hemoglobin (deoxyHb), using the near infrared lights around the wavelength of 800 nm. However, some reports seem to be not brain activation but a skin blood flow. Some reports are also showing deoxyHb increases, this is contradictory to the blood oxygenation level dependent (BOLD) theory of fMRI. The BOLD theory is founded on the decreasing of the deoxyHb. The purpose of this research is to examine the technique of measuring brain activation correctly with the free posture measurement system. It is hard to demonstrate that the data mainly reflects the brain activation. One of the proving methods is to measure parts of whole body other than a brain. 2200 2000 2100 1500 2000 1000 500 0 2 4 6 8 1800 10 2000 4000 1500 3000 1000 2000 1900 0 2 4 (sec) 6 8 10 Wrist Forehead 3000 2400 1000 500 0 1 2 3 4 5 6 7 0 (sec) (sec) NIR 1 NIR 2 Methods 2300 (arb.

Unit) We developed the wearable system, which can measure each part of the whole body. One probe of the system has two light sources and one detector. Two light sources are near-infrared LEDs of two wavelengths. Now optical measurement is used for not only NIRS (2 or more lights, near infrared, some include visible) but the pulse oximeter (2 LEDs, one is visible and the other is near infrared), the plethysmography (1 LED, visible), etc. A pulse rate can be calculated as a periodic change of hemoglobin, and it is strongly influenced of autonomic nerves and of a motion of the whole body. This system was induced into a higher sampling rate than conventional NIRS, so that a pulse waveform could be exposed. Several pieces of the whole body, such as both hands, the head, and a breast, were evaluated using this system. The analog output of a pulse waveform measured by this system and that by the pulse oximeter (Nihon Kohden Corp., Japan) were compared. Upper arm Malleoulus modialis 2200 2600 2400 2100 (arb.
