Voxelwise and ROI analysis during free recall. a, The whole-brain contrast of free recall nonclustered greater than free recall clustered produced activation in right caudate. b, No difference in activation at free recall for clustered and nonclustered words was evident in DLPFC. c, Anterior VLPFC (x, y, z = −56, 31, −7) showed greater activation during free recall for nonclustered words than for clustered words (*p < 0.05). d, Voxelwise contrast of output position greater than baseline, highlighting activation in caudate (x, y, z = −7, 15, 7).
