PROBLEM TO BE SOLVED: To provide a bioinstrument which measures brain functions of a plurality of subjects simultaneously.SOLUTION: The bioinstrument is provided with measuring terminals for measuring blood kinetics of living bodies using light and an intensive control unit for carrying out data acquisition and analysis presentation by controlling a plurality of measuring terminals. Each measuring terminal is constructed of a plurality of probes 101 for irradiating the scalp with light and for detecting the light, a measurement control section 111 for acquiring detected light volume data and storing the data in an external recording medium 113, a radio transmission section 112 for communicating with the intensive control unit, and a battery 114. Light sources 102 and light detectors 103 are arranged on the probe 101.COPYRIGHT: (C)2009,JPO&INPIT【課題】同時に複数の被験者の脳活動を計測することができる生体計測装置を提供する。【解決手段】光を用いて生体の血液動態を計測する計測端末と、複数の計測端末を制御しデータ取得と解析表示を行う集中制御装置を設ける。計測端末は,頭皮上から光を照射,検出するための複数のプローブ101と,検出光量データを取得し外部記憶媒体113に蓄積する計測制御部111と,集中制御装置と通信を行う無線通信部112と、電池114より構成される。プローブ101上に光源102と光検出器103を配した。【選択図】図2
