All structures are listed in order from greatest to least probability of being a member of the labelled regions within the atlas.
Abbreviations: ATR = anterior thalamic radiation; CST = corticospinal tract; IFOF = inferior fronto-occipital fasciculus; ILF = inferior longitudinal fasciculus; SLF = superior longitudinal fasciculus; UF = uncinate fasciculus.
Significant clusters (p < .05) containing <100 voxels were excluded.
