The Brain Atlas Concordance Problem: Quantitative Comparison of Anatomical Parcellations
A: Rendering of three anatomical regions in the left temporal lobe as delineated by two different brain atlases. The largest region, Superior Temporal from the ICBM atlas (see Materials and Methods for atlas descriptions), shown in yellow, overlaps both the Superior Temporal Gyrus (blue) and the Middle Temporal Gyrus (red) regions in the AAL atlas to differing degrees. B: The same region boundaries drawn as projections in the three cardinal directions. An examination of the patterns of overlap in just 3 regions points to the complexity of the concordance problem.
