fMRI results for (A) subtraction vs. multiplication (both strategies) and (B) calculation vs. retrieval (both operations). The activations in the images were thresholded at p < 0.001 uncorrected, showing only clusters significant at p < 0.05, family-wise error (FWE)-corrected at the cluster level. The images were generated with BrainNet Viewer (Xia et al., 2013).
