fMRI results of SPM(F) contrasts (p < 0.05, FDR corrected) for the effects of modulation of selection (high selection vs low selection) and updating (updating vs no updating) at the time of cue presentations within the memory delay. The independent experimental manipulations of selection and updating were associated with differential activations in separate sets of frontoparietal cortical regions. There was no significant interaction between the factors of selection and updating. vmPFC, Ventromedial prefrontal cortex; IPL, inferior parietal lobule; PHG, parahippocampal gyrus; BG, basal ganglia/putamen.
