Outline of Final Research Achievements |
Motor functions in brain tumor patients were assessed by fMRI. The locus of primary sensory motor activation during contralesional hand grasp was displaced by the tumor, suggesting functional compromise and/or reorganization in the central sulcus region. Their contralesional cerebellum activation during contralesional hand grasp was also increased as compared to normal subjects, representing the first evidence that the cerebellum is involved in the functional reorganization in brain tumor patients. Intraoperative language functions were studied using NIRS. Cortical stimulation of Broca’s area elicits hemodynamic responses of NIRS in Wernicke’s area via cortico-cortical connectivity, demonstrating visualization of cortico-cortical evoked responses in language systems. These results can contribute to understand the mechanism for functional reorganization in brain tumor patients and provide important information on developing new therapy for brain tumors based on reorganization.
