动词理解的神经基础已经被证明是难以捉摸的，部分原因是被评估的动词类别范围有限。本研究对16名健康青年进行了运动动词和认知动词意义的探讨。我们观察到不同的模式激活每个动词子类：运动动词与招聘左腹侧颞枕叶皮层，双侧前额叶皮层和尾状核，而认知动词与左后外侧颞激活。这些发现与动词子类的神经表征是不同的这一主张是一致的。虽然“感觉-运动”假说可能在解释与运动动词相关的激活中发挥作用，但与认知动词相关的皮质激活的左后外侧颞叶分布不能轻易地用“感觉-运动”假说来解释。我们认为，左后外侧颞叶激活支持词汇语义处理方面的神经表征的命题知识有助于认知动词。(C)2002 Wiley-Liss，Inc.
The neural basis for verb comprehension has proven elusive, in part because of the limited range of verb categories that have been assessed. In the present study, 16 healthy young adults were probed for the meaning associated with verbs of MOTION and verbs of COGNITION. We observed distinct patterns of activation for each verb subcategory: MOTION verbs are associated with recruitment of left ventral temporal-occipital cortex, bilateral prefrontal cortex and caudate, whereas COGNITION verbs are associated with left posterolateral temporal activation. These findings are consistent with the claim that the neural representations of verb subcategories are distinct. Although the "sensory-motor" hypothesis may play a role in explaining activation associated with MOTION verbs, the left posterolateral temporal distribution of cortical activation associated with COGNITION verbs cannot be easily explained by the "sensory-motor" hypothesis. We suggest that left posterolateral temporal activation supports aspects of lexical semantic processing concerned with the neural representation of propositional knowledge contributing to COGNITION verbs.
