Figure 3:

Cortical Thickness Comparisons: Lateral and medial views of maps of the difference in cortical thickness between the two species are shown in the first column accompanied by a vertical scale such that yellow to red colours indicate that the cortex is relatively thicker in humans than chimpanzees (scaled values > 0) and light to dark blue colours (scaled values < 0) indicate that the cortex is relatively thicker in chimpanzees than humans. The second column shows those regions of the Deskian-Killany atlas where the cortex is found be significantly thicker in humans and the third column shows regions where chimpanzees have significantly thicker cortex.
