Neural correlate of reading in bilinguals

Abstract

This paper does not intend to carry out a systematic or complete review of the literature, but rather aims to offer a critical view by the authors about the functional brain organization during reading in bilinguals. Firstly, a critical analysis of different theoretical proposals about the reading process is presented, with particular emphasis on the Dual-Route Cascade Model for being the most influential theory in the field. Then, we analize the main theoretical proposals about the neurobiological substrate based mainly on functional neuroimage studies. The main factors that influence this neural correlate during reading in bilinguals are extracted and the findings regarding them of the most recent studies are presented. Finally, a critical analysis is made about the main limitations of the research on this topic and challenges and future research lines in the field are discussed.
