Figure 7

Subject 7. (A) Bipolar AP EEG and 12 virtual sensor channels showing onset of generalized ictal onset in unaveraged signals filtered in bandwidth 20–70 Hz, digitized at 600 Hz. Red arrow indicates VS location V7 in right parietal. Ictal onset at V7 precedes by 120 ms the ictal onset in left parietal V6 (blue arrow). (B) Subject’s MRI scan showing VS V7 location in right parietal lobe (at red arrow and crosshairs). (C) Overview of ictal onset from right parietal lobe. (D) Second generalized ictal onset. Blue arrow indicates VS location V6 in left parietal Ictal onset at V6 precedes by 83 ms the ictal onset in right parietal V7 (red arrow). (E) Subject’s MRI scan showing VS V6 location in left parietal lobe (at blue arrow and crosshairs). (F) Overview of ictal onset from left parietal lobe.
