Steps in the analysis of an MEG spike include reviewing: (A) MEG tracing, (B) EEG tracing, (C) MEG signal selection from (D) magnetic isofield map, (E) dipolar electro-magnetic field pattern where the primary current is represented by an arrow (green), and (F) localization through sECD method yielding a dipole model (yellow) that is coregistered to MRI.
