PROBLEM TO BE SOLVED: To use a simple and reliable reference evaluation standard for identifying and detecting the functional state of activity by checking respective two pike cells in image data matrices at the interval of N/2 row concerning the coincidence of inverse signal changes. SOLUTION: In side a nuclear spin resonance device, a stimulation unit 3 to be controlled by a pulse generator 5 is provided. Image data sets before and after a stimulus are prepared by an image data calculation into 4 and displayed like images on a monitor 8 in case. A coincidence calculation unit 6 identifies and detects the coincidence of inverse signal changes at two pike cells deviated just for the N/2 row of two image data matrices. Thus, the detected and locally found activity of the brain is simultaneously displayed on the monitor 8. The image data calculation unit 4, coincidence calculation unit 6 and pulse generator 5 are controlled bny a control unit 7.
