<p><P>PROBLEM TO BE SOLVED: To provide a sensitive state judging method for quantitatively and accurately measuring the sensitive state of a human being without needing a special measurement environment. <P>SOLUTION: The oxidating hemoglobin concentrations and/or reducing hemoglobin concentrations in the blood at measurement portions of the brain surface layer of a subject 1 are measured in time series by a near-infrared spectroscopy. From the data on the variation with time of the measured oxidating hemoglobin concentration and/or the data on the variation with time of the measured reducing hemoglobin concentration, the correlation coefficient for each unit time (for each sampling period) about sets of two different items of data selected by permutation/combination is computed. The pattern of the variations with time of the computed cross correlation coefficients about the sets of two different items of data is analyzed by a predetermined judging method, thereby quantitatively measuring the sensitive state of the subject. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
