abstract = {Specialization of brain areas and subregions, as well as
their integration into large-scale networks are key
principles in neuroscience. Consolidating both local and
global cortical organization, however, remains challenging.
Our study developed a new approach to map global cortex-wise
similarities of microstructure, structural connectivity, and
functional interactions, and integrate these patterns with
maps of cortical arealization. Our analysis combined
repeated high-field in-vivo 7 tesla (7T) Magnetic Resonance
Imaging (MRI) data collected in 10 healthy adults with a
recently introduced probabilistic post-mortem atlas of
cortical cytoarchitecture. We obtained multimodal
eigenvectors describing cortex-wide gradients at the level
of microstructural covariance, structural connectivity, and
intrinsic functional interactions, and then assessed inter-
and intra-area differences in cortex-wide embedding based on
these multimodal eigenvectors. Inter-area similarities
followed a canonical sensory-fugal gradient, with primary
sensorimotor cortex being the most distinctive from all
other areas, while paralimbic regions were least
distinctive. This pattern largely corresponded to functional
connectivity variations across different tasks collected in
the same participants, suggesting that the degree of global
cortical integration mirrors the functional diversity of
brain areas across contexts. When studying heterogeneity
within areas, we did not observe a similar relationship,
despite overall higher heterogeneity in association cortices
relative to paralimbic and idiotypic cortices. The results
were replicated in a different dataset. Our findings
highlight a close coupling between cortical arealization and
global cortical motifs in shaping specialized versus
integrative human brain function.},
