PROBLEM TO BE SOLVED: To provide a brain function measurement system capable of measuring the nervous activity of the brain of a testee against stimulation by a high space- time resolution and analyzing the activity of the brain. SOLUTION: This brain function measurement system is provided with a stimulation presentation device 10, a magnetic field measurement device 20, a data processor 30 for judging the appearance of emotional movement by the stimulation and a recognition process and a data display device 40 for displaying an analyzed result in the data processor 30. When standardized stimulation is presented by the stimulation presentation device 10, a brain magnetic field generated inside the brain of the testee 1 is measured by the high space- time resolution by the magnetic field measurement device 20. The data processor 30 calculates current density distribution (or distribution of current dipole) for indicating the spread of the nervous activity based on obtained brain magnetic field data. Thus, the appearance of the emotion movement of the testee 1 and the recognition process are accurately judged. |
