Description of the clusters activated (Targets+) or deactivated (Targets-) by the Targets, and activated by rare distractors (Novels+), together with their respective projection on a transparent brain. The fixed effect statistical values are given for a threshold t = 3.10 (pnc = 0.001 one-tail, df = 1593.7) with an extent threshold of 100 voxels (pnc = 0.004, pc = 0.059 corrected, 1 resel = 106 voxels). The first column presents the probability to obtain the specified number of clusters (second column). The third column indicates the corrected probability for each cluster, and the fourth column, the number of voxels per cluster. The fifth column presents the corrected probability for the given voxel together with the uncorrected Target and p values (sixth and seventh column). For the same voxel, the eighth column provides the results of the subject conjunction analysis for "population inference" in two ways. If the voxel is active in all the subjects at pnc ≤ 0.05, then the minimal percentage of the population that should present at least the same significance level is given (95% confidence interval). If one or more subjects are below that threshold, then the lowest significance is given in p value. The MNI coordinates together with the anatomical sites and Brodmann areas are provided in the subsequent columns. Smoothness: FWHM = 9.6 × 9.6 × 9.3 mm. Search volume: 1337 cm3 (167142, 2 × 2 × 2-mm voxels).
