Final answer:
Diffusion tensor imaging (DTI) provides information about white matter that connect brain areas to one another.
Step-by-step explanation:
Diffusion tensor imaging (DTI) provides information about white matter that connect brain areas to one another. White matter is a type of nervous tissue that is found only in the brain and spinal cord, and it facilitates communication between gray matter areas. DTI measures the movement of water molecules in the brain, which can help identify the direction and integrity of these white matter tracts.
