We have evaluated the use of phase synchronization to identify resting state functional connectivity (RSFC) in the language system in infants using functional near infrared spectroscopy (fNIRS). We used joint probability distribution of phase between fNIRS channels with a seed channel in the language area to estimate phase relations and to identify the language system network. Our results indicate the feasibility of this method in identifying the language system. The connectivity maps are consistent with anatomical cortical connections and are also comparable to those obtained from functional magnetic resonance imaging (fMRI) functional connectivity studies. The results also indicate left hemisphere lateralization of the language network.
我们评估了使用相位同步来识别使用功能近红外光谱 (fNIRS) 的婴儿语言系统的静息状态功能连接 (RSFC)。我们使用语言区域中的种子通道与 fNIRS 通道之间的相位联合概率分布来估计相位关系并识别语言系统网络。我们的结果表明该方法在识别语言系统方面具有可行性。连接图与解剖皮质连接一致，也可与从功能磁共振成像 (fMRI) 功能连接研究中获得的结果相媲美。结果还表明语言网络的左侧半球偏侧化。
