Abstract: In classical neuroimaging, the activity of each voxel is considered separately. However, it was recently demonstrated that there are significant stimulation-specific differences between adjacent voxels at the group level. With this approach, the activity of adjacent voxels in the same condition is compared, and the direction of the highest increase of activity in the neighbourhood of each voxel is established as a gradient vector per voxel. Using this vector approach, we compared fMRI, EEG and MEG spatial differential activity during different ...
