An Embodied Study Of Semantic Understanding Of Body Action Word

The semantic understanding view of embodied cognition holds that sensorimotor brain regions are involved in the processing and representation of action word semantics.At present,a large number of functional magnetic resonance studies have verified the embodiment of embodied semantic understanding,but the embodiment of Chinese language materials through the perspective of resting state is relatively lacking.In this study,resting state functional magnetic resonance imaging(rs-f MRI)was used to select Chinese action kana that conform to the rules of orthography as learning materials,and explored the neurophysiological mechanism related to the processing of Chinese action words through regional homogeneity analysis,amplitude of low-frequency fluctuations analysis,degree centrality analysis and functional connection analysis.The results show that the corresponding action practice is added to the verb learning process,and after learning,the brain connection between the semantic understanding brain area and the sensorimotor cortex changes significantly.The results of regional homogeneity analysis showed that the difference before and after learning activated the left anterior central gyrus,anterior cerebellar lobe and left prefrontal lobe.The results of f-amplitude of low-frequency fluctuations analysis showed that there were significant differences in the activation of the left superior frontal gyrus and the left middle frontal gyrus.The anterior and posterior differential activation of degree centrality is mainly the right superior frontal gyrus and bilateral middle temporal gyrus;The differential activation brain regions obtained by the before and after analysis of the functional connections of the whole brain were mainly distributed in the occipital,temporal and frontal lobes.In summary,after verb learning,not only the semantic comprehension brain area changed significantly in the resting state,but also the motor cortex found significant changes,which verified the embodiment of the learning of Chinese action words.
