Vision

Of all the sensory systems, the greatest amount of neural tissue is devoted to vision, and blindness is one of the most disabling sensory losses. White matter plays a crucial role in vision; the optic tracts and the thalamocortical radiations convey visual input from the eyes to the occipital cortex for central processing. A variety of visual deficits may follow cerebral white matter lesions; examples include blindness from bihe-mispheric demyelinative disease in patients with MS and hemianopia from a vascular lesion in the occipital white matter.
