New insights into the functional significance of the frontal aslant tract: An anatomo–functional study using intraoperative electrical stimulations combined with diffusion tensor imaging-based fiber tracking

Abstract

We used the method of direct electrostimulation combined with navigated tractography to map the frontal “aslant” tract, enabling us to perform reliable anatomo–functional correlation in a patient undergoing awake surgery to remove a left frontal glioma. The findings enhanced our understanding of the organization of language within the human brain.
