Determining the traffic pattern of human brain. (a) Average of the structure-positive function matching matrix across subjects in the Lausanne 234 atlas, where diagonal entries are deemed accurate matches. As neighboring regions within the same hemisphere are ordered consecutively in the matching matrix, we observe that most of the mismatches occur between either neighboring or contralateral regions. (b) Matching various structure-based connectomes with full positive functional connectomes, we observe that weighted communicability achieves the highest matching accuracy. (* indicates a significant group difference, obtained by a paired t-test with p≤0.05 after FDR correction)
