We have produced a population-based 180-area per hemisphere human cortical parcellation using exceptionally high quality multimodal data from hundreds of Human Connectome Project subjects aligned using an improved areal feature-based cross-subject alignment method
Inspired by an observer-independent post-mortem architectural parcellation approach, we developed a semi-automated neuroanatomical approach adapted to non-invasively acquired multi-modal magnetic resonance imaging data
Though algorithms determined the final areal borders, the multi-modal data were carefully interpreted by neuroanatomists, the properties of each cortical area were documented, and each area was named in relation to the extant neuroanatomical literature
A crossvalidation showed that the areas forming the parcellation were robustly and statistically significantly different from their neighbours across multiple modalities. We identify this parcellation as HCP-MMP1.0, with version 1.0 anticipating future refinements as better data become available
Though we made extensive use of the HCP’s specialized task fMRI battery when generating the parcellation, we showed that task fMRI data is not essential for future studies aiming to use the areal classifier to automatically define the cortical areas in their subjects
