Figure 9

FMAER and source analysis, 5 year old with language delay. The top section (A) shows 20 channels of a scalp recorded FMAER with channel designation displayed below corresponding waveforms. Amplitude scale is to the right. The common average reference is employed. The patient demonstrated severe mixed receptive and expressive dysphasia without autistic behavioral features. Note the excellent right temporal and missing left temporal response. The bottom section (B), displays the FMAER source analysis results for Figure 4. Note the normally placed right temporal primary (red) source and also the aberrantly, superiorly placed and distorted left sided secondary (blue) source. There is no clear left temporal scalp response.
