具身语义学的论点认为，在语言处理过程中获取的概念表征在某种程度上等同于执行所描述的概念所需的感觉运动表征[1-6]。在这里，我们使用功能磁共振成像测试了这样的假设：人类前运动皮层中对动作的执行和观察做出反应的区域（镜像神经元区域 [7-18]）是这些过程中的关键神经结构。参与者观察动作并阅读与脚、手或嘴动作相关的短语。在左半球的运动前皮层中，视觉呈现的动作和文字短语描述的动作的效应器特异性激活之间存在明显的一致性。这些结果表明，在语言刺激引起的动作的概念处理过程中，镜像神经元区域在感觉运动表征的重演中发挥着关键作用。
The thesis of embodied semantics holds that conceptual representations accessed during linguistic processing are, in part, equivalent to the sensory-motor representations required for the enactment of the concepts described [1-6]. Here, using fMRI, we tested the hypothesis that areas in human premotor cortex that respond both to the execution and observation of actions-mirror neuron areas [7-18]-are key neural structures in these processes. Participants observed actions and read phrases relating to foot, hand, or mouth actions. In the premotor cortex of the left hemisphere, a clear congruence was found between effector-specific activations of visually presented actions and of actions described by literal phrases. These results suggest a key role of mirror neuron areas in the re-enactment of sensory-motor representations during conceptual processing of actions invoked by linguistic stimuli.
