Example patient with superficial epileptogenic focus (Pt 5). (A) Schematic of electrode placement. (B) Field map (measured top and modelled bottom) corresponding to the peak of the average interictal spike. (C) Relation on inner skull mesh of MEG dipole (red star) and electrode contact (red circle) with highest spike amplitude, top, and zoomed region, below. (D) Upper panel is the position of MEG dipole on pre-operative MRI scan coronal and sagittal planes; lower panel is post-operative MRI scan. (E) Relationship within patients between MEG source ‘depth’ and presence of MEG spikes, horizontal bar indicating mean depth.
