Figure 9. 2D representation of atlas-free brain networks with N = 95 equal-area nodes, showing average structural connectivity in three age groups: neonates (4 subjects), 6-month-old infants (4 subjects), and adults (4 subjects).

The sum of connections in all subjects of each group (n = 4) was calculated after alignment of their networks to the respective reference network and mapped onto the anatomy of the “reference brain.” Thicker lines represent connections present in more subjects. Bigger spheres represent nodes of higher degree.
