“…46 The method for data preprocessing was in line with those from previous studies. [54][55][56][57] Importantly, both the HbO and HbR signals can be used to characterize the activation and functional network properties of the frontal lobe during the rest or EF tasks. However, most of previous fNIRS work only reported the neuroimaging results based on HbO signals.…”

Executive functions (EFs) associated with the frontal lobe are vital for goal-orientated behavior. To date, limited efforts have been made to examine the relationships among the behavior, brain activation, and topological organization of functional networks in the frontal lobe underlying various EF tasks, including inhibition, working memory, and cognitive flexibility. In this study, functional near-infrared spectroscopy neuroimaging technique was used to systematically inspect the differences in the brain activation and the topological organization of brain networks between various EF tasks in the frontal lobe. In addition, the relationships between brain activation/network properties and task performances and the relationships between brain activation and network properties were, respectively, examined for different EF tasks. Consequently, we have discovered that the nodal and global properties of the resting-state and task-evoked networks, respectively, exhibited significant correlations with the activation of various brain regions during various EF tasks. In particular, the measure that links the neural activation to the topological organization of the brain networks in the frontal lobe can serve as a synergistic indicator to examine the difference between various EF tasks, which paves a way toward a comprehensive understanding of the neural mechanism underlying EFs.

“…Meanwhile, functional near‐infrared spectroscopy (fNIRS) is a noninvasive and affordable neuroimaging technique (Ehlis, Schneider, Dresler, & Fallgatter, 2014; Ferrari & Quaresima, 2012; Vanderwert & Nelson, 2014), which utilize the near‐infrared light (wavelengths between 680–950 nm) to inspect the brain activation by measuring the concentration changes of oxygenated hemoglobin (HbO) and deoxygenated hemoglobin (HbR) (Ferrari & Quaresima, 2012; Jobsis, 1977; Villringer & Chance, 1997). fNIRS studies have been conducted to reveal the neural mechanisms underlying various cognitive tasks (He, Wang, Li, & Yuan, 2017; Lu, Wang, Zhang, Chen, & Yuan, 2017; Wang, Lu, Hu, Zhang, & Yuan, 2018). However, little is performed to use resting‐state fNIRS to decode the organizational characters of brains (Niu & He, 2014; Niu, Wang, Zhao, Shu, & He, 2012).…”

BackgroundAccumulating evidence shows that the dorsal lateral prefrontal cortex (dlPFC) is implicated in personality traits. In this study, resting‐state functional near infrared spectroscopy (fNIRS) combined with small‐world analysis was utilized to examine the relationship between the network properties of dlPFC and personality traits.MethodsThirty college students (aged between 20 and 29) were recruited from the University of Macau campus, whose personality scores were accessed with the NEO‐FFT questionnaire. Graph theory combined with resting‐state fNIRS data was used to quantify the network properties of dlPFC, whereas Pearson correlation analysis was performed to generate the relationship between the small‐world indicators and personality scores.ResultsCompared to matched random networks, the resting‐state brain networks exhibited a larger clustering coefficient (C p, 0.1–0.66), shorter characteristic path length (L p, 0.1–0.66), and higher global (E g, 0.1–0.66) and local efficiency (E loc, 0.1–0.65). In particular, conscientiousness (r = −0.63) and neuroticism (r = 0.40) respectively showed negative and positive correlation with the L p.ConclusionsThe resting‐state functional brain networks in dlPFC exhibited the small‐world properties. In addition, participants with higher conscientiousness scores showed a shorter L p.

“…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.
