Figure 1.

Display of the same axial slice (z = 0 mm) from the T₂-weighted JHU template, and the 2010 (center) and 2012 (right) ICBM-DTI-81 atlases (screen shots from ITK-SNAP 2.2.0). Horizontal red lines highlight the increased posterior protrusion of the occipital pole of the left hemisphere in the JHU template, which is consistent with known asymmetry of the brain in right-handed individuals (LeMay and Kido, 1978). For comparison of white matter labels, color-coded overlays have been added to the structural images (all label maps used the same color lookup table). The cross-hair cursor points to the same point in the right brain hemisphere (according to image coordinates) in all three atlases. The label under the cursor (circled in red) correctly denotes “EC-R” (#33) in the JHU label map, but “EC-L” (#34) in the 2010 ICBM-DTI-81 label map. In the 2012 ICBM-DTI-81 label map, label #34 now corresponds to “EC-R” due to changed label lookup table. Note also the relabeling of previously mislabeled regions in the brain center, apparent from changed region colors inside the red box.
