“…suggested to play a role in semantic processing (12). In this bundle, simultaneous bilinguals demonstrated higher FA values than the other two groups, signifying, according to the authors, more effective semantic processing for this group.…”

“…These tracts have been heavily implicated in L2 learning, with Luk and colleagues (5) reporting increased FA values in the right IFOF and Mohades and colleagues (11) in the left IFOF for bilinguals vs. monolinguals. Because this bundle has been implicated in semantic processing (12), the observed effect may signify more efficient semantic processing in bilinguals, which can be related to the fact that bilinguals need to constantly select between L1 and L2 naming alternatives (19).…”

Recent studies suggest that learning and using a second language (L2) can affect brain structure, including the structure of white matter (WM) tracts. This observation comes from research looking at early and older bilingual individuals who have been using both their first and second languages on an everyday basis for many years. This study investigated whether young, highly immersed late bilinguals would also show structural effects in the WM that can be attributed to everyday L2 use, irrespective of critical periods or the length of L2 learning. Our Tract-Based Spatial Statistics analysis revealed higher fractional anisotropy values for bilinguals vs. monolinguals in several WM tracts that have been linked to language processing and in a pattern closely resembling the results reported for older and early bilinguals. We propose that learning and actively using an L2 after childhood can have rapid dynamic effects on WM structure, which in turn may assist in preserving WM integrity in older age.bilingualism | immersion | white matter | second language acquisition | TBSS

“…Evaluation of resectability may be augmented with addition of diffusion tensor imaging to visualize the position and integrity of white matter tracts deep to and around the lesion. 5,27 Alternative approaches that have been advocated and could be considered include PET and magnetoencephalography/magnetic source imaging, depending on the experience, expertise, and availability of technology at a particular center. 5,51 Regardless of technique used, preoperative maps should be evaluated by a neurosurgeon who is experienced in interpreting these maps to determine the best surgical approach.…”

The adjacency of intracranial pathology to canonical regions of eloquence has long been considered a significant source of potential morbidity in the neurosurgical care of patients. Yet, several reports exist of patients who undergo resection of gliomas or other intracranial pathology in eloquent regions without adverse effects. This raises the question of whether anatomical and intracranial location can or should be used as a means of estimating eloquence. In this review, the authors systematically evaluate the factors that are known to affect anatomical-functional relationships, including anatomical, functional, pathology-related, and modality-specific sources of variability. This review highlights the unpredictability of functional eloquence based on anatomical features alone and the fact that patients should not be considered ineligible for surgical intervention based on anatomical considerations alone. Rather, neurosurgeons need to take advantage of modern technology and mapping techniques to create individualized maps and management plans. An individualized approach allows one to expand the number of patients who are considered for and who potentially may benefit from surgical intervention. Perhaps most importantly, an individualized approach to mapping patients with brain tumors ensures that the risk of iatrogenic functional injury is minimized while maximizing the extent of resection.
