(A) MEG (275 channels) recording from an 11-year-old boy with BECTS. (B) Selected channels to illustrate the centro-temporal spike and lower trace, V1, and the virtual sensor electrode from the SAMg2 algorithm. (C) Flux potential and dipole illustration. (D) The synthetic aperture magnetometer (SAM) image overlaid onto the partially inflated 3D render of the structural MRI brain scan, showing the location in the inferior and anterior bank of the central sulcus. (E) The equivalent current dipole.
