Table 4. Tractographical approach for parieto-occipital tracts.

White matter tract	Seed mask	Waypoint and termination mask	Exclusion mask
Optic radiation	Pericalcarine cortex	Eroded thalamus	All other cortical regions
Dorsal visual stream	Pericalcarine cortex	Inferior parietal cortex	Thalamus
Splenium of the corpus callosum	Left lateral occipital cortex	Right lateral occipital cortex*	All other cortical regions
Posterior corona radiata (PCR) (occipital)	All occipital regions	Cerebral peduncle	All other cortical regions
Posterior corona radiata (PCR) (parietal)	All parietal regions	Cerebral peduncle	All other cortical regions

The Freesurfer seed, waypoint, termination, and exclusion masks used in fiber tractography to delineate examined parieto-occipital tracts. *For the tract through the splenium of the corpus callosum, a callosal waypoint mask was also used.
