The processed DTI data to visualize white matter tracts in the brain. a The placement of the regions of interests (ROIs) on the color-coded fractional anisotropy (FA) map and the corresponding apparent diffusion coefficient (ADC) map. #1: genu of corpus callosum, #2: internal capsule, #3: splenium of corpus callosum, #4: corona radiate. The regions outside of the brain parenchyma were masked out from the display. For the FA color-coding scheme, red, green, and blue colors were used for left–right, dorsal–ventral, and rostral–caudal directions, respectively. b Bilaterally visualized DTI tractography of the corticospinal tracts and optic radiations in sheep (software-generated pseudo-coloring was used)
