abstract = {The brain is a physically embedded and heavily
interconnected system that expresses neural rhythms across
multiple time scales. While these dynamics result from the
complex interplay of local and inter-regional factors, the
relative contribution of such mechanisms across the cortex
remains unclear. Our study explores geometric,
microstructural, and connectome-level constraints on
cortex-wide neural activity. We leverage intracranial
electroencephalography recordings to derive a coordinate
system of human cortical dynamics. Using multimodal
neuroimaging, we could then demonstrate that these patterns
are largely explainable by geometric properties indexed by
inter-regional distance. However, dynamics in transmodal
association regions are additionally explainable by
incorporation of inter-regional microstructural similarity
and connectivity information. Our findings are generally
consistent when cross-referencing electroencephalography and
imaging data from large-scale atlases and when using data
obtained in the same individuals, suggesting
subject-specificity and population-level generalizability.
Together, our results suggest that the relative contribution
of local and macroscale constraints on cortical dynamics
varies systematically across the cortical sheet,
specifically highlighting the role of transmodal networks in
inter-regional cortical coordination.},
