Regions modulated by memory strength but not significantly activated by search. Statistical activation map showing areas with increasing (red) or decreasing (blue) activity with increasing study level during recall (p < .05, corrected for multiple comparisons), with an exclusion mask of regions in which activity differed (p < .05) between the forgotten and classify trials. Clusters are overlaid on the lateral pial surface of the Talairach and Tournoux N27 average brain and coronal cross-sections (indicated with dashed lines) of the mean anatomical image of all participants. Graphs display the time course of the percent signal change (±SE) in the left DLPFC (A) and left and right superior (B, D) and inferior (C, E) parietal cortex for low-, medium-, and high-study recall conditions.
