MRI of the White and Gray Matter in the Brain - W-Radiology
In the subcortical part (deeper tissues) of the brain lies the white matter that contains axons or nerve fibers enclosed with myelin(6). The myelin sheath protects the nerve fibers from injury, enhances the transmission and communication of the electrical nerve signals in the axons, and gives the white matter color(7). … See more
