Gray matter parcellation based on local diffusion properties

Keypoints

  • Using FA and local principal diffusion direction in combination with k-means clustering to subdivide subcortical areas.
  • Charting the radiality of the principal diffusion direction on the cortical sheet.
  • We found plausible subdivisions of caudate nucleus, putamen, amygdala and thalamus.
