Embodied semantics theory asserts that the meaning of action-related words is neurally represented through networks that overlap with or are identical to networks involved in sensory-motor processing. While some studies supporting this theory have focused on Chinese characters, less attention has been paid to their semantic radicals. Indeed, there is still disagreement about whether these radicals are processed independently. The present study investigated whether radicals are processed separately and, if so, whether this processing occurs in sensory-motor regions. Materials consisted of 72 high-frequency Chinese characters, with 18 in each of four categories： hand-action verbs with and without hand-radicals, and verbs not related to hand actions, with and without hand-radicals. Twenty-eight participants underwent functional MRI scans while reading the characters. Compared to characters without hand-radicals, reading characters with hand-radicals activated the right medial frontal gyrus. Verbs involving hand-action activated the left inferior parietal lobule, possibly reflecting integration of information in the radical with the semantic meaning of the verb. The findings may be consistent with embodied semantics theory and suggest that neural representation of radicals is indispensable in processing Chinese characters.

*** May 11,2023,the internationally renowned journal Nature announced that a first draft of the human pangenome reference has been constructed[1].This research was carried out by the Human Pangenome Reference Consortium(HPRC).One month later,on June 14,2023,a pangenome reference of 36 Chinese populations was published on journal Nature[2],which was performed by Chinese Pangenome Consortium(CPC).As the scientists pointed out that since the Human Genome Project(HGP)published the human reference genome,it provided a reference blueprint for genomic ***,the limitations of the human reference genome have gradually emerged,and it is difficult to reflect the genome diversity of the"human"species.
