Source Localization Model, Five Dipole + BR regional Sources. (a) Illustrates the three GFP peaks consistent with the PCA components in response to the complete data set (b) displays the overlay of the five-dipole model (purple) and residual variance (red) and (c) illustrates the final five-dipole model + BR regional sources (purple). Notice that the model waveforms (purple) remain similar for both models, but the residual variance (red) is reduced in the final model shown in (c). (d) Illustrates SWFs obtained at the three-time intervals, 90–120 ms, 170–200 ms and 270–300 ms, consistent with the PCA peaks (e) illustrates the five localized source dipoles (red ACN1-R, blue ACN1-L, pink ACP2-R, green ACP2-L) plus the added BR regional sources (BESA 7.1 Research). See text for detail. GFP global field power, PCA principal component analysis, SWFs source waveforms, BR brain region.
Foged et al. show in their paper “Learn to interpret voltage maps: an atlas of topographies” how to correctly interpret surface voltage maps in order to localize the underlying generators. The educational review paper addresses the learning objective “1.4.4 Interpret topographic (voltage) maps” of the ILAE curriculum. The authors state that “using a didactic approach, we explain how to read voltage maps and provide an atlas of voltage maps.” (Epileptic Disorders. [Epub ahead of print])
