Dendritic Arbor

In a Radiolab (http://www.radiolab.org/2007/jun/04/) broadcast on zoos the term "dendritic arbor" was used to describe the growth of dendrites after a monkey was transferred to a more enriched environment.

My immediate thought was to formulate a sentence using the term.  After a few attempts, perhaps influenced by having read an article about hallucinogenic mushrooms leading to a gruesome murder I settled for "Drugs were implicated in the pruning of his dendritic trees."  Not bad, but something involving topiary would have been better, e.g., "His dendritic trees look like topiary."
