Comparison of the positively loaded regions (99th percentile) of MCI 1 and 2 and principal component 1 (PC1) of the corresponding group analysis. Axial slices of the T1 weighted canonical single MNI subject overlaid with the positively loaded regions of the 99th percentile. MCI 1 and 2: mean component image; PC1: principal component observed in the group analysis representing sensory guided motor activity [9]; z: z coordinate in Talairach space. PM: premotor cortex. MI: primary motor cortex, SI: primary somatosensory cortex, PC: precuneus, SPL: superior parietal lobule, pACC: paralimbic anterior cingulate cortex, PBN: parabrachial nucleus, PG: periventricular grey.
