Default Brain maturity brings increasing long range functional connectivity

Children's brains and adults share the same 4 core networks, but children have more highly locallized brain connectivity whereas adult brains show more long range connectivity with significant functional effects, moving toward a more distributed model. But even in the children, there were still enough long distance connections that the "small world" model still seemed to apply.

Quote:
"Instead of having networks made of brain regions that are distant from each other but functionally linked, most of the tightest connections in a child's brain are between brain regions that are physically close to each other.

...clearly shows a switch from localized networks based on physical proximity to long-distance networks centered on functionality.

...Scientists already knew that children had many fewer long-distance links among brain regions than adults, but when they looked more closely they found there were enough of these links and nodes with multiple connections to establish small-world organization."
