Recorded MEG and EEG signals for 1 representative spike. In MEG, the latency between the peak signal intensity in the right and left frontal sensors was 21 ms. It was more difficult to characterize the spikes in EEG. The latency between the peak signals in the right frontal MEG sensors and the right frontal bipolar EEG-derivation (FP2-F8) was approximately 12 ms. The EEG channel names follow the International Federation of Clinical Neurophysiology (IFCN) standard..

Top: The lateral views of the dSPM obtained by temporally aligning the peak of all left frontal lobe spikes (A) and labeling the peak as time 0 ms. Activity in the right frontal lobe (B) can be seen at 21 ms before the left frontal activity (A) at 0 ms. Bottom: The dSPM obtained by temporally aligning the peaks of all right frontal lobe spikes (C). No preceding left frontal lobe activity was found. The white arrowhead indicates the location of cortical dysplasia lesion..

3T MR imaging shows the location of cortical dysplasia in the right frontal lobe (arrowhead).
