The anatomical definition and functions of white matter tracts frequently involved in autism

White matter tracts	Category	Connection	Function related to autism
ATR	Projection fiber	Dorsomedial thalamic nucleus to prefrontal cortex through the anterior limb of internal capsule	Executive function and planning complex behaviors
Corpus callosum	Commissural fiber	The cortices of the two cerebral hemispheres	Cognitive and social function
Cingulum	Long-range associative fiber	Cingulate gyrus to the anterior thalamic nuclei	Visuospatial processing and memory access
IFOF	Long-range associative fiber	Occipital cortex, temporo-basal areas, and superior parietal lobe to the frontal lobe	Semantic processing
ILF	Long-range associative fiber	Occipital lobe to the anterior temporal lobe	Face and emotion recognition
SLF	Long-range associative fiber	Frontal lobe to parietal lobe and partially to temporal lobe	Visuospatial attention, language auditory comprehension, articulatory processing, reading, and lexical access
UF	Long-range associative fiber	Lateral orbitofrontal cortex and Broadmann area 10 to anterior temporal lobes	Episodic memory, language, and social emotional processing

ATR, anterior thalamic radiation; IFOF, inferior fronto- occipital fasciculus; ILF, inferior longitudinal fasciculus; SLF, superior longitudinal fasciculus; UF, uncinate fasciculus
