Frequent edge sets in human connectome graphs

Abstract

One way to examine the connections between the distinct parts of the human brain is the braingraph, or the connectome. The nodes of the connectome are not neurons, but distinct areas of the gray matter, which can be found in any average and healthy human brain, so we can compare whether two edges are present in the graphs between the same nodes. The connectomes are mapped from human brains by di usion MR imaging. In previous studies research had been made on the data of the Human Connectome Project, now we use the connectomes of 423 subjects on di erent scales from 83 to 1015 vertices. The connectomes are available in GraphML format at https://braingraph.org. Our purpose was to analyze the connectomes and nd frequent edge sets with the apriori algorithm and compare them between female and male brains.
