Foci of significantly greater activation during the attention tasks when the groups were compared (only peaks with z > 2.8 reported here). Localisation, Tailarach co-ordinates (TLRC) and corresponding Brodmann areas (BA) represents the voxel with the maximum z-score; HP, healthy participants; L, left; POCs, presumed obligate carriers; R, right.
