Neuroimaging results – group, region and task level dissociations. Percentage signal change for patients and controls in the reality monitoring and working memory contrasts, within the a priori left medial anterior PFC voxel: x = −16, y = 56, z = 14; right medial anterior PFC voxel: x = 20, y = 56, z = 9; left dorsolateral PFC voxel: x = −45, y = 25, z = 25; and right dorsolateral PFC voxel: x = 43, y = 38, z = 18, derived from previous studies.
