动词有两个不同层次的意义。一个层次反映了每个动词的独特性，被称为“根”。另一个层次由一个更为简单的表示组成，它由给定类中的所有动词共享，称为“事件结构模板”。我们探讨了以下假设，特别是关于动作动词的运动特征，这两个不同层次的语义表征可能对应于镜像神经元系统的两个不同层次。假设1：根水平的运动功能的动词意义是部分subserved的躯体映射镜像神经元在左初级运动和/或运动前皮层。假设二：动词意义的模板水平运动特征部分地受到左侧额下回Brodmann区44中代表性更强的示意性镜像神经元的影响。越来越多的证据支持这两种假说所提出的神经解剖学主张，即动词意义的每一个层次都与指定的皮层区域有关。然而，到目前为止，还没有研究满足所有必要的标准来支持这两个假说提出的更具体的神经生物学主张，即动词意义的每一个层次都与相关大脑区域的镜像神经元有关。这就需要证明，在这些区域内，相同的神经元群体参与了（a）对动词意义的特定运动特征的语言处理，（B）执行具有相应运动特征的动作，以及（c）观察具有相应运动特征的动作。
Verbs have two separate levels of meaning. One level reflects the uniqueness of every verb and is called the “root.” The other level consists of a more austere representation that is shared by all the verbs in a given class and is called the “event structure template.” We explore the following hypotheses about how, with specific reference to the motor features of action verbs, these two distinct levels of semantic representation might correspond to two distinct levels of the mirror neuron system. Hypothesis 1: Root-level motor features of verb meaning are partially subserved by somatotopically mapped mirror neurons in the left primary motor and/or premotor cortices. Hypothesis 2: Template-level motor features of verb meaning are partially subserved by representationally more schematic mirror neurons in Brodmann area 44 of the left inferior frontal gyrus. Evidence has been accumulating in support of the general neuroanatomical claims made by these two hypotheses—namely, that each level of verb meaning is associated with the designated cortical areas. However, as yet no studies have satisfied all the criteria necessary to support the more specific neurobiological claims made by the two hypotheses—namely, that each level of verb meaning is associated with mirror neurons in the pertinent brain regions. This would require demonstrating that within those regions the same neuronal populations are engaged during (a) the linguistic processing of particular motor features of verb meaning, (b) the execution of actions with the corresponding motor features, and (c) the observation of actions with the corresponding motor features.
