In rolandic epilepsy, equivalent current dipoles of spikes are located and concentrated in the rolandic regions and have regular directions. In self-limited epilepsy with autonomic seizures, equivalent current dipoles of spikes are located and concentrated bilaterally in the rolandic regions and right occipital area. The directions of each equivalent current dipole in each area are regular as if three small round toothbrushes are placed in each of the three areas. Small yellow circles represent locations, and yellow arrows represent directions of equivalent current dipoles. Blue circles and arrows represent bilateral somatosensory evoked magnetic field.
