The neural correlates of action language processing are still debated within embodied cognition research and little is known about the flexible involvement of modality-specific pre-motor system and multimodal high-level temporo-parietal regions as a function of explicit and implicit tasks. A systematic review and the Activation likelihood estimation (ALE) meta-analyses on functional neuroimaging studies were performed to identify neural correlates of action language processing activated during explicit and implicit tasks. The contrast ALE meta-analysis revealed activation of modality-specific premotor area and inferior frontal areas during explicit action language tasks while a greater activation of posterior temporo-occipital areas emerged for implicit tasks. The conjunction analysis revealed overlap in the temporo-parietal multimodal high-level regions for both types of tasks. Functional specialization of the middle temporal gyrus was found where the more posterior-occipital part resulted activated during implicit action language tasks whereas the antero-lateral part was involved in explicit tasks. Our findings were discussed within a conceptual flexibility perspective about the involvement of both the modality-specific and multimodal brain system during action language processing depending on different types of tasks.
在具身认知研究中，动作语言处理的神经相关性仍存在争议，对于特定于模态的前运动系统和多模态高级颞顶区域如何根据显式和隐式任务灵活参与，人们知之甚少。我们对功能神经影像学研究进行了系统评价和激活似然估计 (ALE) 荟萃分析，以确定在显式和隐式任务中激活的动作语言处理的神经相关性。对比 ALE 荟萃分析显示，在显式动作语言任务中，特定于模态的前运动区和额下回区域被激活，而在后颞枕区域则出现了更大的激活。联合分析显示，两种类型的任务都在颞顶多模态高级区域存在重叠。发现中颞叶具有功能特异性，其中更靠后的枕叶部分在隐式动作语言任务中被激活，而前外侧部分则参与显式任务。我们的研究结果在概念灵活性的视角下进行了讨论，即根据不同类型的任务，动作语言处理既涉及特定于模态的大脑系统，也涉及多模态大脑系统。
