Relationship between Neural Activity and Executive Function: An NIRS Study

Objective . This study examined the relationship between neural activity and executive function (EF) by near-infrared spectroscopy (NIRS). In addition, an oral reading span test (RST) was used to explore this association. Methods . Fifteen adults participated in the study. We used the RST and simple reading as the two tasks. Results . The RST score and cortical hemodynamic response in the left inferior frontal gyrus were significantly correlated. Conclusion . Based on the oral RST performance assessment and NIRS examination, the present findings suggest a relationship between EF and cortical activation.
