The aim of this study was to design and validate a protocol using functional near-infrared spectroscopy (fNIRS) for the assessment of overt reading of irregular words and nonwords. All participants showed significant activations for both irregular word and nonword reading (compared with baseline) in the inferior frontal gyri, the middle and superior temporal gyri, and the occipital cortices bilaterally. Results also revealed the implication of the bilateral inferior frontal gyri in the grapheme-to-phoneme conversion characterizing the phonological pathway of reading as higher [HbT] values were found in nonword than in irregular word reading. Our findings thus confirmed that fNIRS is an appropriate technique to assess the neural correlates of overt reading.
