A multiscale cerebral neurochemical connectome of the rat brain
(a) Purple edges show the links, which belong to the maximum matching and the driver nodes are highlighted as rectangles. The nodes are colored according to the brain regions they belong to. (b) The number of driver nodes as function of graph density, while sequentially removing the longest links from the G125×125 network (red curve), starting from the intact network. Degree-preserving randomizations/rewirings were done on the intact network, generating 500 randomized graphs. The edge removal process and driver node measurements were repeated on each of the randomized versions (average: black curve, SD: gray area). The inset shows the same figure but on a log-scale for the y axis.
