本研究的目的是确定语言理解中的句法-语义界面的神经相关。这是通过检查我们所说的“论点层次结构”来实现的，即，确定句子中的哪个参与者是动词所表达的事件的“行动者”，哪个是“受动者”。为了确定论元层次结构加工的神经基础，我们操纵了三个已知的因素，即论元顺序，动词类和形态歧义，影响德语论元层次结构的复杂性。增加的论点层次要求产生增强的激活网络的下额叶，后上级颞，运动前区和顶叶区。此外，该网络的组件由个体因素进行了差异调制。特别是，左后上级颞沟表现出增强的敏感性形态信息和句法实现的动词为基础的论点层次结构，而激活的左下额回（pars opercularis）对应线性化的要求，是独立的形态信息。因此，我们认为，德国，后上级颞叶和额叶下部区域从事的actorhood提取从m morphosyntagical结构和顺序实现的层次解释的依赖关系，分别。(c)2005年爱思唯尔公司All rights reserved.
The present fMRI study aimed at identifying neural correlates of the syntax-semantics interface in language comprehension. This was achieved by examining what we refer to as "argument hierarchy construction", i.e., determining which participant in a sentence is the "Actor" and which is the "Undergoer" of the event expressed by the verb. In order to identify the neural bases of argument hierarchy processing, we manipulated three factors known to influence the complexity of argument hierarchy construction in German, namely argument order, verb class and morphological ambiguity. Increased argument hierarchization demands engendered enhanced activation in a network of inferior frontal, posterior superior temporal, premotor and parietal areas. Moreover, components of this network were differentially modulated by the individual factors. In particular, the left posterior superior temporal sulcus showed an enhanced sensitivity for morphological information and the syntactic realization of the verb-based argument hierarchy, while the activation of the left inferior frontal gyros (pars opercularis) corresponded to linearization demands and was independent of morphological information. We therefore argue that, for German, posterior superior temporal and inferior frontal regions engage in the extraction of actorhood fro m morphosyntactic structure and in the sequential realization of hierarchical interpretive dependencies, respectively.
