Figure 14

FMAER, Landau-Kleffner syndrome, CP5 spike source analysis. Source analysis for the patient described in Figure 13 is shown for the average of 12 CP5 (left parietal-temporal) spikes during a short electrographic seizure and at the time of the initial study. The patient’s FMAER is shown in Figure 13A. Display convention for Figure 14 is as for Figure 4 although data represent the CP5 spike average. Waveforms for the three sources are shown in the middle pane with the corresponding source locations and orientations shown in the right hand pane. The primary source is shown in red, secondary source in blue, and tertiary source green. Note (middle pane) that the primary source leads the other sources in time and is located in the basilar temporal region. Note that the secondary lower amplitude and later occurring source is located in the left angular gyrus. The time scale for all waveforms is 125 msec.
