<p>PROBLEM TO BE SOLVED: To provide an apparatus for searching a person having correlation with respect to cerebral nerve activity to indicate data corresponding to the searching result. SOLUTION: A change in the concentration of a metabolic substance in a living body is measured by using data processing terminals (1-5,1-6 and 1-7) equipped with a light irradiator for irradiating an object to be examined with light, a photodetector for detecting the light emitted from the light irradiator to propagate through the object to be examined and an antenna (1-11) and the measured result is transmitted to the central data processor (1-1) on a network. The central data processor (1-1) is equipped with a memory device (1-3) and a signal processor (1-4) and calculates the correlation between the stored data. When correlation not less than a definite value is obtained, this state is transmitted to the data processing terminals (1-5, 1-6 and 1-7) possessed by the object to be examined.</p> |
