To compare the event-related potentials (ERPs) waves of verbs and prepositions in the brain.
We recorded ERPs in the brain while participants judged the legality of the collocation for verbs and prepositions.
Both verbs and prepositions elicited a negativity at the frontal site in 230-330 ms and 350-500 ms window. No difference was seen in 230-330 ms and 350-500 ms window; In difference waves, a negativity was elicited in the left and right hemisphere at about 270-400 ms and 470-600 ms window for both open and closed-class words.
These may demonstrate that prepositions in modern Chinese are probably not a separate class from verbs and that N280 may be not a specific component for only prepositions (or closed-class words).
比较大脑中动词和介词的事件相关电位（ERP）波形。
当参与者判断动词和介词搭配的合法性时，我们记录大脑中的ERP。
动词和介词在230 - 330毫秒和350 - 500毫秒窗口的额叶部位均引发了负波。在230 - 330毫秒和350 - 500毫秒窗口未观察到差异；在差异波中，开放类词和封闭类词在左右半球约270 - 400毫秒和470 - 600毫秒窗口均引发了负波。
这些可能表明现代汉语中的介词可能与动词并非不同的类别，并且N280可能并非仅为介词（或封闭类词）的特定成分。
