“…The dorsolateral prefrontal hub is suggested to be involved in multiple demand system, functioning in cognitive-attentional-executive control, language switching, as well as the management of non-literal meanings [ 61 ]. This result well supports previous studies that have identified the activation of the dorsolateral prefrontal region in simultaneous language translation [ 17 , 23 , 24 , 62 ], suggesting such cognitive processes as planning, inhibition, task monitoring, and language switching are involved when completing the task [ 34 , 35 , 36 ]. It is worth mentioning that most studies in the existing literature have identified the dorsolateral prefrontal hub in the left hemisphere [ 5 , 6 ].…”

Recent neuroimaging research has suggested that interpreters and non-interpreters elicit different brain activation patterns during simultaneous language translation. However, whether these two groups have different functional connectivity during such a task, and how the neural coupling is among brain subregions, are still not well understood. In this study, we recruited Mandarin (L1)/English (L2) interpreters and non-interpreter bilinguals, whom we asked to perform simultaneous language translation and reading tasks. Functional near-infrared spectroscopy (fNIRS) was used to collect cortical brain data for participants during each task, using 68 channels that covered the prefrontal cortex and the bilateral perisylvian regions. Our findings revealed both interpreter and non-interpreter groups recruited the right dorsolateral prefrontal hub when completing the simultaneous language translation tasks. We also found different functional connectivity between the groups. The interpreter group was characterized by information exchange between the frontal cortex and Wernicke’s area. In comparison, the non-interpreter group revealed neural coupling between the frontal cortex and Broca’s area. These findings indicate expertise modulates functional connectivity, possibly because of more developed cognitive skills associated with executive functions in interpreters.

“…Alta, ikerketa gutxi dago oraindik ere (Obidina, 2015), eta aditu batzuek salatu dute beste modalitate batzuk baino gutxiago aztertu dela (Trovato, 2012). Bereziki, ikusizko itzulpenaren alderdi kognitiboari erreparatzeko beharra azpimarratu da (De Laet, 2012), eta horretan zentratu dira azkenaldian argitaratutako ikerketa ugari (Kokanova et al, 2018;Ren et al 2019;Wenchao eta Defeng, 2020).…”

“…The left/right superior temporal gyrus has been linked to semantic and syntactic processing , and the left/right inferior parietal lobule has been associated with language comprehension (Ramachandran and Hubbard, 2003;Hartwigsen et al, 2010) and high-order language activities (Brownsett and Wise, 2010). Above all, a neural association has been suggested between interpreting and the prefrontal cortex (Klein et al, 1995;Ren et al, 2019), Broca's area (Tommola et al, 2000;He et al, 2017;Shinozuka et al, 2021), the superior temporal gyrus (Hervais-Adelman et al, 2017;Shinozuka et al, 2021), and inferior parietal lobule (Price et al, 1999). By focusing on these brain areas, this study aimed to identify the neural activation patterns associated with directionality in interpreting.…”

Recent neuroimaging research has suggested that unequal cognitive efforts exist between interpreting from language 1 (L1) to language 2 (L2) compared with interpreting from L2 to L1. However, the neural substrates that underlie this directionality effect are not yet well understood. Whether directionality is modulated by interpreting expertise also remains unknown. In this study, we recruited two groups of Mandarin (L1)/English (L2) bilingual speakers with varying levels of interpreting expertise and asked them to perform interpreting and reading tasks. Functional near-infrared spectroscopy (fNIRS) was used to collect cortical brain data for participants during each task, using 68 channels that covered the prefrontal cortex and the bilateral perisylvian regions. The interpreting-related neuroimaging data was normalized by using both L1 and L2 reading tasks, to control the function of reading and vocalization respectively. Our findings revealed the directionality effect in both groups, with forward interpreting (from L1 to L2) produced more pronounced brain activity, when normalized for reading. We also found that directionality was modulated by interpreting expertise in both normalizations. For the group with relatively high expertise, the activated brain regions included the right Broca’s area and the left premotor and supplementary motor cortex; whereas for the group with relatively low expertise, the activated brain areas covered the superior temporal gyrus, the dorsolateral prefrontal cortex (DLPFC), the Broca’s area, and visual area 3 in the right hemisphere. These findings indicated that interpreting expertise modulated brain activation, possibly because of more developed cognitive skills associated with executive functions in experienced interpreters.
