前記被検体頭部内部を透過した透過光を検出する光検出手段と、
前記光検出手段で検出された前記透過光の強度から、前記被検体頭部の血液量を演算するデータ処理装置と、
前記データ処理装置の処理結果を表示する表示手段とを有し、
前記データ処理装置は、前記光検出手段による計測データと、前記計測データの時間的な変動に対するフィッティング関数との差をDsとし、安静期間におけるDsの自乗平均値と、前記被検体の脳機能を活動させるタスク期間におけるDsの自乗平均値との比を所定の閾値と比較し、前記血液量変化の有無を判定することを特徴とする意思表示装置。A light irradiation means for irradiating the subject's head with light;
Light detecting means for detecting transmitted light transmitted through the inside of the subject head;
A data processing device for calculating the blood volume of the subject's head from the intensity of the transmitted light detected by the light detection means;
Display means for displaying a processing result of the data processing device;
The data processing apparatus uses Ds as a difference between measurement data obtained by the light detection means and a fitting function with respect to temporal variation of the measurement data, and calculates a mean square value of Ds during a rest period and a brain function of the subject. A intention display device characterized by comparing the ratio of the squared mean value of Ds during a task period to be activated with a predetermined threshold value to determine the presence or absence of the blood volume change.
