Everything in biological systems depends on everything else; all variables are global, all methods are public, and all definitions are recursive. It's all spaghetti code- there is nothing like the separation of functionality that we impose on our designed artefacts for the sake of our limited minds. A signal needed to be sent from one place to another, and the brain has the machinery for endocrine functions already, so why not have it handle it? So while this is a quite valid and interesting result, it's not nearly as exciting as the popular press is going to make it out to be.
