Regions ranked further (i.e. rank >37) have a perfectly null contribution to the model. ER stands for Expected Ranking. The region size is displayed in voxels. The weights were averaged across folds (except for computing ER). A region label ending in ‘L’ (resp. ‘R’) means left (resp. right) hemisphere region
