Table 3.

Brain regions of interest analyzed by fMRI BOLD responses (mean t-scores) to 0-back vs. 2-back cognitive tasks performed before and after TILS (Pre vs. Post), and in untreated controls matched by age, sex and carotid artery intima-media thickness. Coordinates (Talairach or TAL X, Y, Z), Brodmann area and voxel size are given for each region of interest.
