“…Previous studies showed that these regions would be activated in bilingual production tasks and other bilingual processing tasks involving phonological and semantic retrieval (Bleser et al, 2003;Chee et al, 1999Chee et al, , 2001Chee et al, , 2003Klein et al, 1995Klein et al, , 1999Klein et al, , 2006Price et al, 1999;Tan et al, 2005).…”

Using the ER-fMRI technique, the present study was designed to investigate the neural substrates of language switching among secondlanguage learners. Twelve Chinese college students who were learning English were scanned when they performed language switching tasks (naming pictures in their first [L1, Chinese] and second [L2, English] languages according to response cues). Compared to non-switching conditions, language switching elicited greater activation in the right superior prefrontal cortex (BA9/10/32), left middle and superior frontal cortex (BA8/9/46), and right middle cingulum and caudate (BA11). When the direction of switching was considered, forward switching (from L1 to L2), but not backward switching (from L2 to L1), activated several brain regions related to executive functions (i.e., bilateral frontal cortices and left ACC) relative to non-switching conditions. These results suggest that neural correlates of language switching differ depending on the direction of the switch and that there does not seem to be a specific brain area acting as a "language switch".

“…Only a few functional neuroimaging studies in bilinguals have specifically addressed these interesting issues (Chee et al, 1999a(Chee et al, ,b, 2001Dehaene et al, 1997;Illes et al, 1999;Kim et al, 1997;Klein et al, 1994Klein et al, , 1995Perani et al, 1996Perani et al, , 1998Price et al, 1999).

“…On the other hand, when proficiency was kept constant in these studies, age of acquisition per se did not seem to have a major impact on brain representations of L2, at least at the macroscopic (brain area) level. Specifically, in the case of word generation and, in general, of production tasks, there was some evidence that a lower degree of language proficiency may be associated with differences in brain activity in anterior brain structures, such as Broca's area and the basal ganglia (Chee et al, 1999a;Yetkin et al, 1996). Conversely, in the case of comprehension, the proficiencyrelated differences involved the temporal lobes, in particular the temporal pole (Dehaene et al, 1997;Perani et al, 1996Perani et al, , 1998.…”

Abstract:We assessed the effects of age of acquisition and language exposure on the cerebral correlates of lexical retrieval in high-proficient, early-acquisition bilinguals. Functional MRI was used to study Spanish-Catalan bilinguals who acquired either Spanish or Catalan as a first language in the first years of life. Subjects were exposed to the second language at 3 years of age, and have used both languages in daily life since then. Subjects had a comparable level of proficiency in the comprehension of both languages. Lexical retrieval with the verbal fluency task resulted in the well-established pattern of left hemispheric activation centered on the inferior frontal region. The effect of age of acquisition was assessed by dividing the subjects into two groups, on the basis of the language acquired first (Catalan-born or Spanish-born bilinguals). Functional comparisons indicated that less extensive brain activation was associated with lexical retrieval in the language acquired earlier in life. The two groups were also different in language usage/exposure, as assessed with a specific questionnaire; in particular, the exposure to the second language (Spanish) was less intensive in the case of Catalans. This was reflected in a significant interaction, indicating a more extensive activation in Catalans during production in Spanish. Overall, these results indicate that, during a production task, both age of acquisition and language exposure affect the pattern of brain activation in bilinguals, even if both languages are acquired early and with a comparable level of proficiency.

“…These two brain regions are critical for language processing (e.g., Chee et al, 1999;Petersen et al, 1990;Poldrack et al, 1999;Price et al, 1996;Tan et al, 2000). In terms of the role of the language areas in the processing of mathematical terms, two other issues need to be discussed.…”

Neural correlates of numbers and mathematical terms

Numerical processing has been demonstrated to be subserved typically by the brain regions around the bilateral intraparietal sulcus (IPS). The goal of the current study was to investigate whether the processing of mathematical terms shared the same brain regions with numerical processing. Healthy adult participants performed semantic distance judgment tasks on five types of materials, including geometric terms, algebraic terms, linguistic terms, words for tools and other common objects, and Arabic numbers. Brain activation was measured with functional magnetic resonance imaging (fMRI). The results showed that geometric terms had greater activation than algebraic terms, linguistic terms and tool words in the horizontal IPS, but algebraic terms did not have greater activation than linguistic terms and tool words in this region. Arabic numbers showed greater activation than non-number materials (including geometric terms, algebraic terms, linguistic terms and tool words) in the bilateral IPS, right inferior frontal gyrus and bilateral middle frontal gyrus, but the non-number materials showed stronger activation in the left inferior frontal gyrus and left middle temporal gyrus. These results suggest that the brain area for the processing of numbers (the left IPS) seems to be involved in semantic processing of geometric terms, but not that of other mathematical terms such as algebraic terms. Both algebraic and geometric terms share similar brain organization with basic semantic processing in the left temporal and frontal regions.
