Abstract：To compare the methods orientating of hubs and mapping it to the anatomical brain regions .In this issue,we applied two methods to find the hubs in the network respectively,node degree and betweenness centrality (BC ).Then vulnerability was employed to compare the two methods,which needs to delete nods in the network and compare the global efficiency between the intact network and lesioned network.It showed that BC method was a more effective method since the hub′s vulnerability of BC method was larger than node degree method and the consistency was better.We further applied BC method to the anatomical orientation of hubs, which found that hubs gather in the frontal and parietal lobe on the previous result.The results lay foundation for studying the function of the hubs in the network.It is helpful for the further research of the anatomical mapping in information delivery.
