Node connection strength in Neurotree.
Each node in Neurotree can be characterized by its mean distance from every other
node. Below is a histogram of mean distances for every node in the tree.
(The final bin includes nodes that are not connected to the main tree.)

20 most tightly coupled nodes.
Below are the nodes with shortest mean distance. Note the strong bias
toward systems and, in particular, the visual system. This suggests either that visual neuroscientists are highly promiscuous or that the population of the tree is biased by having been started in a vision lab. This question will only be answered with more data!

Distribution of individual connectivity.
Another way to look at the Neurotree graph is to plot a histogram of
researchers (nodes) based according to the number of immediate connections
(edges) they have to other researchers. The final bin includes nodes with
or more connections. The actual distribution has a very long tail, with a maximum of 109 connections. Thanks to Adam Snyder for suggesting this analysis!
