Activations are significant at p < .001 (uncorrected; t > 3.93; cluster threshold > five voxels), which corresponds to a whole-brain alpha of <.05 based on a Monte Carlo simulation conducted with AFNI's AlphaSim. The cluster's Brodmann's area (BA), its size in voxels (Cluster Size), and the coordinates (MNI space, in millimeters) and t value of its peak voxel are provided. Hemi = hemisphere; n/a = non-applicable; p. orbit = pars orbitalis; L = left; R = right.

aHippocampal cluster size at p < .005 uncorrected, t > 3.20, α < 0.5, based on a Monte Carlo simulation conducted within a hippocampal mask (small volume correction).
