Figure 10

FMAER and source analysis, 7 year old with language delay. Display convention is as for Figure 9. The clinical presentation was also quite similar. Again note the absent left temporal scalp response, top section (A). Again source analysis below (B) shows a near normal right temporal primary response (red). The left sided secondary response (blue) shows near normal morphology but is unusual in terms of the anterior placement within the temporal lobe and the unusual source orientation. A tertiary source (green) is observed in the right medial cingulate gyrus probably related to excessive stimulus amplitude (see Hagenmuller at al. [23]).
