摘要：The neural correlates of nouns and verbs are the œntral issue of a long-standing debate in neuropsychology. The double dissociability of the two grammatical categories and of the respective morphosyntactic processes has been firmly established in neuropsychological studies (eg, Shapiro & Caramazza, 2003; Drucks, 2002) leading to the hypothesis that verbs and nouns, as well as the involved morphosyntactic operations, have distinct neural representations. However，neuroimaging findings provide only inconsistent support to these hypotheses，which could be due in part to the limitations intrinsic to the various neuroimaging tools. In the present study, the neural representation of Noun/Verb distinctions is studied by means of a novel technique - magnetoencephalography (MEG), which is characterized by excellent temporal resolution and good spatial resolution. The goal of the study is to establish whether distinct neural substrates are involved in processing nouns and verbs in the œntext of phrases.
