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.

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.
