Note. All activations are significant at p < 0.001, corrected based on Monte Carlo simulations run with AFNI's AlphaSim program (t₍₂₆₎ > 3.700 for perception and mental replay, and t₍₂₄₎ > 3.750 for reactivation; cluster threshold > 20 voxels). The Brodmann area (BA), coordinates (MNI space, in millimeters), and t value of the cluster's peak voxel are provided. Clu. size, cluster size; Hemi, hemisphere; L, left; R, right.
