Surface-based subfield atlas. (A, B) Individual MRI on which hippocampal subfields are manually and schematically delineated based on Duvernoy atlas.6 Our segmentation protocol excludes the subiculum at the level of hippocampal body and tail.20 (C) Surface of the entire hippocampus for the same individual. By registering the given individual surface to the template representing healthy population, we obtain the borders between subfields (white dot lines) on the surface. CA, cornu ammonis; DG, dentage gyrus; Sub, subiculum
