Memory inhibition engaged caudate, putamen, and GPe more reliably than action prevention. Top row: Clusters are presented on coronal slices of a high-resolution MNI atlas. Reference lines for the coronal slices are presented in the sagittal plane. Bottom row: Clusters are displayed on high-resolution parcellations of the caudate, putamen, and external globus pallidus (GPe). All clusters are thresholded using cluster-level inference (p<.05, uncorrected p<.001, threshold permutations=1000).
