(A) Degree distribution of links. The black trace corresponds to the degree for all
the links (directed and undirected), the blue one to the degree of sources (out-directed
links) and the red trace to sinks (in-directed links), averaged over subjects. Observe
that (a) both directed link degree distributions are very similar, and (b) there is
a scale-free trend, more marked when all links are considered. The dotted line corresponds
to a power-law of 3/2. (B) Small-world topology of the networks. Clustering and average
minimal path for functional networks (open circles), equivalent ErdÃ¶s random networks
(red crosses) and equivalent regular lattices (blue x's). Data points correspond to
different subjects and tasks. (C) Assortative mixing of directed networks. The horizontal
axis represents the total degree of each node, and the vertical axis the average degree
of the first neighbors; all the data points correspond to one single subject.
