大脑的概念或语义与感觉运动系统之间的关系仍然存在争议。在这里，我们测试了41名慢性中风患者的手动和概念能力，以检查它们之间的关系。手动能力通过使用外骨骼机器人完成的任务进行评估。语义能力进行了评估与隐式以及明确的语义任务，为动词和名词。结果表明，动作词加工的选择性损伤程度可以通过动作词加工的通达性损伤程度来预测。此外，内隐语义的措施表现出相关性的全球达到参数，而明确的语义相似性判断任务预测的行动启动性能。这些结果表明，动作概念是动态接地通过运动模拟，更多的细节模拟更明确的语义任务。这是大脑的感觉-运动系统和概念系统之间存在密切因果关系的证据。
The relationship between the brain’s conceptual or semantic and sensory-motor systems remains controversial. Here, we tested manual and conceptual abilities of 41 chronic stroke patients in order to examine their relationship. Manual abilities were assed through a reaching task using an exoskeleton robot. Semantic abilities were assessed with implicit as well as explicit semantic tasks, for both verbs and nouns. The results show that that the degree of selective impairment for action word processing was predicted by the degree of impairment in reaching performance. Moreover, the implicit semantic measures showed a correlation with a global reaching parameter, while the explicit semantic similarity judgment task predicted performance in action initiation. These results indicate that action concepts are dynamically grounded through motoric simulations, and that more details are simulated for more explicit semantic tasks. This is evidence for a close and causal relationship between sensory-motor and conceptual systems of the brain.
