Relationship between AC encoding and AB forgetting. (a) Activation in the posterior hippocampus (MNI coordinates: −30, −33, −9) extending into parahippocampal cortex (−30, −30, −18) during AC encoding was associated with spared forgetting of AB pairs (PFDR < .05 for both regions, small volume correction at voxel level; for complete results see Supplementary Table 7 online). (b) Beta values showing the relationship between AC encoding activation and subsequent AB memory separately for AB pairs associated with high and low reward; drawn from hippocampal region of interest from contrast depicted in Figure 2a. Error bars indicate ± within-subject error; coordinates in MNI space; FDR: false discovery rate; small volume correction conducted using Anatomical Automatic Labeling (AAL) atlas to generate mask of entire medial temporal lobe, including hippocampus, parahippocampal cortex, perirhinal cortex, and entorhinal cortex.
