Descriptions of commonly used bundles and their functions in DTI studies [23–28]

Bundles	Type of fiber	Connections between brain areas	Functions
Corpus callosum	Commissural fiber	Connects identical cortical areas in both brain hemispheres	Processing input and output signals from each hemisphere; coordination of thought processes and behavior
Cingulum bundle	Association fiber	Connects the areas of the frontal, parietal, temporal lobes; connects the subcortical nuclei to the cingulate gyrus; connects various elements of the limbic system with each other	Controls executive functions; attention; emotional and motivational processes; socio-emotional processes; episodic memory; pain
Uncinate fasciculus	Association fiber	Connects the lateral parts of the orbito-frontal cortex with the anterior part of the temporal lobe	Episodic memory; language processes; socio-emotional processes
Arcuate fasciculus	Association fiber	Connects the frontal lobe to the temporal lobe	Speech comprehension; speech and language processes
Superior longitudinal fascicles	Association fiber	Connects the frontal lobe to the parietal lobe and partly to the temporal lobe	Visual-spatial functions; motor control; hearing and articulation processes; understanding the content of heard and read text; speech processes; using tools
Inferior longitudinal fasciculus	Association fiber	Connects the occipital lobe to the temporal lobe	Visual processes; emotional processes; behavior related to vision; visual cognition; visual memory
