To　study　the　topological　differences　between　the　left　and　right　functional　brain　networks　during　visual　word　recognition　in　task　mode,　with　the　45　subjects＇　tfMRI　data　from　the　OpenfMRI　project　database　of　Word　and　Object　Processing,　the　left-and-right　functional　brain　networks　under　the　conditions　of　words　and　consonant　strings　were　constructed　based　on　the　anatomical　brain　atlas　automated　anatomical　labelling　(AAL),　respectively.　The　degree　centrality,　global　efficiency,　clustering　coefficient　and　local　efficiency　of　the　two　hemispheres　were　statistically　compared,　and　the　relationship　between　regions　of　interest　(ROIs)　of　AAL　and　the　language　network　of　functional　brain　atlas　Willard-499　was　investigated.　Significant　statistical　differences　were　identified　between　the　left　and　right　brain　network　indexes　in　the　sparsity　domain　under　the　two　experimental　conditions.　The　four　significant　differences　of　the　indexes　were　0,　0,　0　and　0　under　the　consonant　string　experiment　condition,　and　0,　5%,　0,　and　44%　under　the　word　experiment　condition,　respectively.　The　sharp　contrast　on　the　percentage　of　significant　differences　between　the　clustering　coefficient　and　the　local　efficiency　was　identified　under　the　word　experiment　condition.　The　left　and　right　functional　brain　networks　could　be　differentiated　in　local　morphology　during　the　visual　word　recognition.　©　2022,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
