[The long-associative pathway of the white matter: modern view from the perspective of neuroscience].

This review presents basic information about white matter tracts of the human brain, with a special emphasis being placed on long associative fibers (superior and inferior longitudinal fascicles, inferior frontooccipital fascicles, fasciculus arcuatus and fasciclus uncinatus): their structure, history, functions, methods of preoperative and intraoperative identification during neurosurgical operations. Neurological symptoms caused by a damage to each of the above-described long associative fiber are described. There is a detailed analysis of methods of neuropsychological testing and neurophysiological identification in white matter fiber tract mapping in focal brain lesions.
