Three dimensional visualization of the white matter fibers such as corticospinal tract, optic radiation and arcuate fasciculus with relationship to high grade gliomas is helpful, and when used routinely in neuronavigation surgery of high grade glioma does not increase the length of surgery neither increase the neurological deficit rate despite the increased resection in both eloquent and non eloquent areas.
Using MR diffusion tensor imaging, Hubl et al (22) identified white matter changes in the arcuate fasciculus of schizophrenia patients prone to hallucinations, compared with healthy controls and patients who had schizophrenia but not hallucinations.
When compared with normal controls, children who stutter had reduced whitematter integrity only in the left arcuate fasciculus (a tract that underlies the oral-facial motor regions), as measured by fractional anisotropy.
This region came to be known as Wernicke's area, connected to Broca's area by a neural pathway called the arcuate fasciculus.
The band of association fibers responsible for the intra-hemispheric transfer of neural information is the arcuate fasciculus.
sup][5],[6],[7],[8] Complementary diffusion tensor imaging studies have found that the AVHs of schizophrenia are associated with disruptions of white matter integrity in the left arcuate fasciculus bundle and interhemispheric auditory fiber bundles.
