EEG时频分析旨在通过测量单个电极各频段的能量变化,揭示事件相关振荡活动。采用该技术,最近的句子加工研究发现,句法与语义过程均与多个频段（θ、α、β或γ）能量变化相联系。此外,不同方面的句法（如语法性、数）和语义加工（语义整合或预期）与不同频段振荡活动相联系。将来的研究应该使用多种EEG能量计算方法,在多种语言中,探讨时态、词序等句法加工所伴随的振荡活动,特别是句法和语义过程相互作用在EEG能量变化上的表现。

As an electrophysiological technique, electroencephalograph （EEG） time-frequency analysis can reveal event-related oscillatory activities by measuring power changes for different frequency bands at each electrode. In the area of sentence processing, using this technique, a large number of recent studies have associated syntactic and semantic processes with power changes at different bands （0, α, β, or γ）. In addition, different types of syntactic （e.g., grammatical gender or number） and semantic processing （semantic integration or prediction） have been linked to oscillatory activities at different bands. Future studies should examine not only oscillatory activities underlying other types of syntactic processing such as tense and word order processing, which haven＇t been investigated so far, but also oscillatory activities involved in the interaction between syntactic and semantic processes. Moreover, further studies should use a variety of methods for analyzing EEG power changes, in a variety of languages, in order to test whether EEG power changes to syntactic and semantic processes are modulated by methodological and linguistic variation.
