F-statistic maps and effect size ratio HR/LR. An example of F-statistic maps for low- and high-resolution data (LR/HR 1⁄4 left/middle) cut off at p<1% (uncorrected) show more extensive and larger fMRI contrast in the former (LR) (left). Right: A voxel-wise comparison by way of the effect size ratio (HR/LR) confirms that LR > HR almost everywhere. Background: mean EPI of the posterior half of a representative axial slice transecting the occipital and inferior temporal lobes.
