structural connectivity
Physical white matter connections between brain regions mapped through diffusion tractography methods.
Full Definition
Structural connectivity refers to the physical anatomical connections between brain regions established through white matter fiber tracts, as mapped using diffusion tensor imaging and tractography techniques. This connectome mapping reveals the brain's structural wiring diagram, showing how different cortical and subcortical areas are anatomically linked through myelinated axonal pathways. Structural connectivity analysis provides insights into brain organization, development, aging, and pathological disruption in neurological disorders.
Usage
Usage note: Distinguish from functional connectivity, which measures temporal correlations rather than physical connections.
