Abstract

Multilinguals’ navigation through three or more language systems utilizing one cognitive system is a phenomenon of recent interest. Few functional near-infrared spectroscopy (fNIRS) studies have focused on brain activations concerning multilinguals. The present study uses picture-naming and fNIRS technique to explore the prefrontal brain activations amongst neurotypical multilinguals belonging to four major provinces of Pakistan. The 26 right-handed participants utilize their native language (Punjabi, Pushto, Sindhi or Balochi), first language (Urdu) and second language (English) distinctively in the experiment. Brain imaging results demonstrate a significant activation of the right prefrontal cortex among the multilingual adults along with left laterality. Moreover, results indicate significant activation of channels demonstrating heavier cognitive load with English in comparison to first or native language(s). The paper suggests that right dorsolateral prefrontal cortex and right medial prefrontal cortex play a significant role in language processing alongside the left prefrontal cortex, exemplifying that peripheral activation during word retrieval, processing and production is a possibility.

通过功能近红外光谱（fNIRS）评估多语言使用者的语言处理。

多语者利用一种认知系统在三种或多种语言系统之间进行导航是最近引起人们兴趣的一种现象。功能性近红外光谱（fNIRS）研究很少关注多语言者的大脑激活。本研究使用图片命名和近红外光谱技术来探索巴基斯坦四个主要省份的神经典型多语者的前额叶脑激活。26名右撇子参与者在实验中使用他们的母语（旁遮普语、普什图语、信德语或俾路支语）、第一语言（乌尔都语）和第二语言（英语）。脑成像结果显示，在多语言的成年人中，右前额叶皮层和左侧边都有显著的激活。此外，研究结果表明，与母语或母语相比，英语通道的显著激活表明英语的认知负荷更重。本文认为，在语言加工过程中，右侧背外侧前额叶皮层和右侧内侧前额叶皮层与左侧前额叶皮层一起发挥着重要作用，说明在单词检索、加工和产生过程中，外周激活是可能的。

期刊介绍： Behavioural Brain Research is an international, interdisciplinary journal dedicated to the publication of articles in the field of behavioural neuroscience, broadly defined. Contributions from the entire range of disciplines that comprise the neurosciences, behavioural sciences or cognitive sciences are appropriate, as long as the goal is to delineate the neural mechanisms underlying behaviour. Thus, studies may range from neurophysiological, neuroanatomical, neurochemical or neuropharmacological analysis of brain-behaviour relations, including the use of molecular genetic or behavioural genetic approaches, to studies that involve the use of brain imaging techniques, to neuroethological studies. Reports of original research, of major methodological advances, or of novel conceptual approaches are all encouraged. The journal will also consider critical reviews on selected topics.
