In case you were wondering.
From a Live Science article today:
"Researchers also checked children's brains for "small-world" organization, another organizational quality present in adult brains. This is the same idea as the game 'six degrees of Kevin Bacon,' which connects any actor or actress to Kevin Bacon in six movies or less through their co-stars.
In this case, the 'co-stars' are nodes in the brain.
'It's the idea of a large network that lets you connect one node with another in a relatively short number of steps via special nodes,' Fair says. 'Like Kevin Bacon, these special nodes have many connections to other nodes, allowing them to help shorten the amount of steps that have to be taken when connecting nodes.'"
