Distribution and location of clustered MEG spike sources. (A) T1-weighted axial brain magnetic resonance imaging (MRI) shows MEG spike sources clustered around the margin of the lesion. Because the spike sources are overlaid in a single axial image, spike sources that are inside the lesion are located superior or inferior to the lesion (patient 2). (B) T2-weighted axial brain MRI shows MEG spike sources clustered on the margin of the lesion (overlaid image of patient 7). (C) T1-weighted axial brain MRI shows MEG spike sources clustered at the margin lateral to the lesion (overlaid image of patient 12). Epileptogenic lesion (arrow) is visible in brain MRI.
