We report an analysis method for inverse presumption of brain current dipoles from the brain magnetic field. By the numerical evaluation simulation code based on the genetic algorithm, one current dipole was presumed at less than 5 mm spatial resolution in all areas such as the parietal region, the temporal region, the frontal region, and the occipital region of the head. In addition, by the shifting aperture method, which excels in the visualization of the continual spatial distribution, several current dipoles could be visualized separately.
