Table 3. Tractographical approach for temporal tracts.
White matter tract | Seed mask | Waypoint and termination mask | Exclusion mask |
Fusiform - amygdala | Fusiform gyrus | Amygdala | All other gm regions |
Fusiform - hippocampus | Fusiform gyrus | Hippocampus | All other gm regions |
Uncinate fasciculus (UF) | Orbitofrontal cortex* | Entorhinal cortex + temporal pole | All other gm regions |
Inferior longitudinal fasciculus (ILF) | Pericalcarine cortex | Inferior temporal cortex | Thalamus + all other cortical regions |
Inferior frontooccipital fasciculus (IFOF) | Lingual gyrus | Orbitofrontal cortex* | Thalamus + all other cortical regions |
The Freesurfer seed, waypoint, termination, and exclusion masks used in fiber tractography to delineate examined temporal tracts. *Orbitofrontal cortex was created by summing the medial orbitofrontal cortex and lateral orbitofrontal cortex.
