Comparison between unscaled (top) and RESCALE-processed (center) group-level activation maps. Both maps show t-values thresholded at |t| = 4.25. Activation clusters remain the same, but (absolute) t-values within the clusters are generally increased after the RESCALE procedure. Bottom: Difference map showing voxels with absolute t-value changes greater than 1. Improvements can be seen in left primary and supplementary motor cortex as well as in the occipital cortex, with no significant differences in t-values in other regions.
