Diffusion MRI has been proposed as a method to
parcellate cortex into functionally distinct regions
based on tractography-derived connectivity features.
However, the accuracy of the parcellation has not been
investigated extensively. This study aimed to validate
DTI connectivity-based cortical parcellation by
comparison to a histological gold-standard. The
comparison reveals the potential and limitations of
connectivity-based parcellation.
