outgoing from both the SMAp areas Left and Right is largely higher than the
CTRL subjects. This result puts in evidence the important role of the
supplementary motor areas (SMAp Left and Right) that increase their outgoing
functional flows to support the diminished activity of their primary motor areas
(MIF Left and Right) during the preparation of this motor act.
The panels at the bottom of Fig. 10.5 show the average profiles of the degree
distributions for SCI and CTRL group, in the Beta frequency band. An
interesting result is that in-degree and out-degree distributions show different
trends within each group.

Right-skew tails of out-degree distributions indicates the presence of few
nodes with a very high level of outgoing connections, while for the in-degree
distributions there are no ROIs in the network with more than six incoming
connections. The inset in each figure illustrates the typical Gaussian profile of
the degree-distributions in random graphs, which appears to be different from
