Design outcomes

Primary

Measure	Time frame
The sources reconstructed with the VBMEG method will be compared to the fMRI activity map. The distance between sources will be calculated. If the distance is too far away from sources from the fMRI activity maps, the source will count as a false positive. When no source is located, while there should be a source, it is a false negative. The distance will be used in a Wilcoxon signed rank test comparing the fMRI activity map with the hd-EEG reconstructed sources.	—
