“…García-Pentón et al (2014) revealed that early bilinguals showed a different WM structural configuration of the brain, developing more highly interconnected and efficient subnetworks to achieve the processing of the two languages, and that these changes seem to be at the expense of decreased efficiency for the whole brain network. This is in line with previous accounts broadly showing that bilinguals are less accurate and slower than monolinguals of each language in linguistic tasks (e.g.…”

“…Hypothesis (Abutalebi & Green, 2007;Green & Abutalebi, 2013), there is just one region predicted by the model that consistently shows up across studies as a structural difference due to bilingualism: the left/right IFG (Hosoda et al, 2013;Klein et al, 2014;Grogan et al, 2012;Luk et al, 2011;García-Pentón et al, 2014). Some of the studies used alternatives to the traditional methods of VBM and ROI-based analysis and analyzed the whole brain to reveal effects of bilingualism in the IFG and in the connections between there and other regions (Luk et al, 2011;Klein et al, 2014;García-Pentón et al, 2014).…”

Abstract:The neuroanatomical bases of bilingualism have recently received intensive attention.However, it is still a matter of debate how the brain structure changes due to bilingual experience since current findings are highly variable. The aim of this review is to examine these structural studies from a methodological perspective and to discuss two major methodological problems that could give rise to this variability. The first problem is sample selection, an issue directly related to the heterogeneous nature of bilingualism. The second problem is the inconsistency in the methods used for the analysis of brain imaging data. This review reveals that although structural changes related to bilingualism have been reported in regions comprising language/cognitive control and language processing, these results are not yet sufficiently numerous or consistent to allow important generalizations to be reached. Consequently, current evidence offers ambiguous support for neural models of bilingualism. This shortcoming in the field is exacerbated by critical methodological differences between studies that only further complicate the matter. We conclude by identifying issues that should be taken into consideration so that studies are more comparable and results are easier to aggregate and interpret. We also point out future directions that would allow for progress in the field.

“…Further evidence of the effect of simultaneous language learning on the WM of early bilinguals was recently provided by García-Pentón and colleagues (15), who compared a group of 13 Spanish-Basque bilinguals and a group of 13 age-matched Spanish monolinguals. García-Pentón and colleagues used a network-based statistics approach (16) and revealed that two WM subnetworks provided more efficient connections among GM structures in bilinguals than monolinguals: first, a network connecting several language-related areas, including the left inferior frontal gyrus (IFG), pars triangularis, superior temporal gyrus, superior frontal gyrus, and the insula, and second, a network connecting the left angular gyrus, superior parietal gyrus, superior temporal pole, superior occipital gyrus, and right superior frontal gyrus.…”

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
