Diffusion tensor imaging of the brain showing the right and left arcuate fasciculus (Raf & Laf), the right and left superior longitudinal fasciculus (Rslf & Lslf), and tapetum of corpus callosum (Ta).<unk>  is a general term for a collection of neurological symptoms caused – via lesions to associational or commissural nerve fibres – by damage to the white matter axons of communication pathways in the cerebrum (not to be confused with the cerebellum), independent of any lesions to the cortex. The behavioral effects of such<unk> s are relatively predictable in adults.<unk> s usually reflect circumstances where regions A and B still have their functional specializations except in domains that depend on the interconnections between the two regions. Callosal syndrome, or split-brain, is an example of a<unk>  from damage to the corpus callosum between the two hemispheres of the brain.<unk>  can also lead to aphasia, left-sided apraxia, and tactile aphasia, among other symptoms. Other types of<unk>  include conduction aphasia (lesion of the association tract connecting Broca’s area and Wernicke’s), agnosia, apraxia, pure alexia, etc.
