While repose topic is unstable the fact that stimulus topic is loaded in the suffering inspection body is removed, the accurate response for the stimulus topic presenting of the suffering inspection body is made measurement possible. In parallel with the presentation of the stimulus presentation section and the aforementioned stimulus which present stimulus to the suffering inspection body, the action the decision of the stability in the time of presentation of the aforementioned repose topic function and the aforementioned repose topic and the stimulus topic which set repose topic and the stimulus topic which have with the brain functional measuring device which measures the brain function of the aforementioned suffering inspection body and the stimulus presentation control section which controls the stimulus which the aforementioned stimulus presentation section presents, as for the aforementioned stimulus presentation control section, they present to the aforementioned suffering inspection body on the basis of function and the said inspection result which inspect the response of the aforementioned suffering inspection body which confronts,On the basis of the said stability, the stimulus topic presentation device in the organism optical measuring device which possesses with the topic presentation control operation which does the control of presentation of the aforementioned repose topic or the aforementioned stimulus topic.安静課題が不安定なまま被検体に刺激課題を負荷することを排除し、被検体の刺激課題呈に対する正確な応答を計測可能にする。被検体に刺激を呈示する刺激呈示部と、前記刺激の呈示と並行して、前記被検体の脳機能を計測する脳機能計測装置と、前記刺激呈示部が呈示する刺激を制御する刺激呈示制御部とを備えており、前記刺激呈示制御部は、前記被検体に呈示する安静課題及び刺激課題を設定する機能と、前記安静課題及び刺激課題対する前記被検体の応答を検知する機能と、該検知結果に基づいて前記安静課題の呈示時における安定度の判定を行ない、該安定度の程度に基づき、前記安静課題もしくは前記刺激課題の呈示の制御を行なう課題呈示制御機能とを有する生体光計測装置における刺激課題呈示装置。
