Synopsis

Connectivity-based parcellation of subcortical structures typically relies on the pre-parcellation of the cortex. Here, we propose an unsupervised data-driven approach for subcortical parcellation based on diffusion tractography without relying on the annotation of cortical regions or fiber tracts.
