Here is My Question:
What is peripheral white matter of both cerebral hemispheres?
"Peripheral white matter" is an inappropriate term. Whoever used the term was either referring to the subcortical white matter or the leukocortical (also called juxtacortical) white matter. We generally use the term leukocortical or juxtacortical when the U fibers are involved, whereas subcortical white matter excludes the U fibers. U fibers are the white matter tracts immediately adjacent to the cortex that supply white connections between one area of the cortex and an adjacent area of the cortex.
