Subcortical U-fibers lesions refer to damage or abnormalities in the nerve fibers beneath the cerebral cortex, the outer layer of the brain. These U-shaped fibers are crucial for communication between different parts of the brain. When lesions occur in these fibers, they can disrupt normal brain function, leading to various symptoms and conditions.
