In the literature, studies on Chinese and English words have accumulated significant insights into the language network in the brain. However, there are not enough studies on sentences and paragraphs in different languages. Previously, we conducted EEG experiments on Chinese and English sentences with/without syntactic errors, suggesting that the two languages differed mainly in the lower frequency range (delta and theta) based on results from event-related potential (ERP) and event-related spectral perturbation (ERSP). In the current study, we investigated phase synchronization in the scalp regions during visual recognition of semantic ambiguity in Chinese and English sentences. Forty right-handed subjects (Average age 26.1±4.6; 20 males) participated in the language tasks. EEGs were recorded during subjects recognizing ambiguity in Chinese/English sentences. Channel-wise EEG time series were preprocessed and analyzed by phase-locking values (PLVs). In both Chinese and English tasks, EEG channels in the frontal, left/right temporal and parietal-occipital regions showed strong within-region connectivity before/after the task onset. The English task had stronger connectivity in the right temporal region than the Chinese task during all time intervals. The Chinese task had stronger frontal-parietal connectivity during 350-650msec after the sentence onset in the 1-7Hz range. In general, the tasks required more temporal activity for semantic monitoring ambiguity in sentences. Semantic recognition of Chinese sentences required the frontal-parietal connectivity in the low frequency range. The results suggest that the language network could differ in semantic recognition between Chinese and English especially during the 350-650msec after the sentence onset.
