Yes, but I am not sure how I would be able to define the location of the electrodes of the different participants in one MRI? Or is it possible to coregister multiple CT scans to one MRI template?
Additionally, we would really want to use the individual MRI's of every participant since the organisation of the sulci can have an impact on the ERP-component we're looking at. So maybe in that case I would better go with option 2?
