Group mean fMRI activation data. Extent of fMRI activation is defined as total (left + right) number of voxels within each region of interest (ROI) showing task-related fMRI activation in novel vs repeated contrast (p < 0.01) divided by total number of voxels in ROI. Greater hippocampal (HF) activation was present in the mild cognitive impairment (MCI) group than controls (*p < 0.03), and lesser hippocampal (**p < 0.005) and entorhinal (ERC; ***p < 0.02) activation was present in the Alzheimer disease (AD) group.
