I was considering making a new topic for this, but I've bothered you guys enough with my constant off-topic messages so I thought I shouldn't start a new thread.
I found some similarities between the mammalian CNS and the concept of cellular neural networks. Specifically, the human brain has a certain module, the neocortical column, which is copied nearly-identically across the surface of the brain. This explains the consistency of the six neuronal layers across the neocortex. These are detailed in the paper "Large-scale model of mammalian thalamocortical systems." (The support pdf is actually a lot more helpful.)
Please let me know if you don't understand something, I don't mind explaining!
