Dear SPMers, please find attached a picture showing the overall activation in the brain (F-contrast over all conditions of the task). Data was normalized with DARTEL over structural T1 images. My question concerns the effect that the glasbrain is just poorly filled. It seems like there are strong extinctions in frontal, frontoparietal and temporal brain regions. Do you know why this happens? (We found this effect in various studies.) Many thanks, Natalie
