        External Email - Use Caution        

Dear Ann,

this looks like “spotty brain decease”, caused by visualizing the source data on the wrong brain model. Are you 100% sure that the model you use for visualization is the same model for which the source space was constructed?

Forward model was computed with 3-layer bem model with oct5 spacing for 2052 sources, for inverse solution the 'fsaverage' trans-matrix was used. I also used standard 'easycap-M1' montage. The original EEG data was pre-processed via BrainVision Analyzer and looks nice at sensor space topomaps. I have already looked for errors related to localization, forward or inverse computations, but still did not find any. Has anyone come across such results before?
