Figure S2 (middle row) Chimpanzee folding variability - surface views
Middle row. For the chimpanzee (middle row), folding differences among individuals are more pronounced, as are the differences between the Yerkes29 group average atlas surface and the individuals (aligned using folding). All primary and secondary gyri and sulci visible in the individuals are discernible in the group average surfaces, but some sulci are shallower in the atlas. For example, the highlighted vertex in the shallow superior frontal sulcus of the group average, lies deep within a sulcus in some hemispheres but near a gyral crown in others (blue and green vertices and arrows).
