(a) Neural activity for the decrease and maintain trials during the memory elaboration phase. Saggital slice shows a region of right inferior frontal gyrus (x = 36, y = 7, z = 22) engaged more by the maintain than decrease trials. (b) Neural activity for the increase and maintain trials during the memory elaboration phase. Saggital slice shows a region of right amygdala (x = 30, y = −1, z = −15) engaged more by the increase than maintain trials. (c) Neural activity for the decrease and increase trials during the memory elaboration phase. Saggital slice highlights greater anterior PFC activity for the decrease condition (e.g., in middle frontal gyrus; x = −44, y = 44, z = 16) but greater ventrolateral PFC activity for the increase condition (e.g., in inferior frontal gyrus; x = −46, y = 18, z = 12).
