%X Instantaneous coherence estimation based on the multivariate autoregressive model (MVAR) was applied to investigate the neural electrophysiological activities and the interaction of functional cortical areas in 10 bilinguals performing Stroop task using Chinese (L1) and English (L2). It was found that:In 1(13~18 Hz)frequency band, the EEG coherence at incongruent situation was higher than that at congruent situation in both L1 and L2, which indicated that 1 was sensitive to the discrimination between the congruent and the incongruent situations; A stronger EEG coherence between frontal and parietal regions in L1 version occurs, compared to that in L2 version. These findings indicated that the interaction of functional cortical areas was enhanced to evaluate the conflicting information of the incongruent stimulus, and stronger interaction between frontal and parietal areas occurred whilst processing the first language compare with the second language.
