Unwanted Metaphors

As regular readers know, I am all for metaphors; I love them like I love the sour jelly beans at the bodega on 92nd Street. But sometimes, enough is enough.

"That's where biological psychiatry was then," she told me. "It was about the brain as a bowl of soup. You whip up a chemical, add it and stir"...

Setting aside the bowl-of-soup model did not mean deciding that neurochemicals weren't important. Rather it meant deciding that neurochemistry, and particularly the chemistry dictating how individual neurons communicate with one another, was probably driven by traffic between different brain areas, and that identifying the patterns in that traffic might yield new understanding. (Or, using another metaphor, if the brain is an orchestra, then the neurochemical approach focuses on how well individual players listen and respond to the players adjacent to them; the network approach, like a conductor, focuses on how the orchestra's sections — strings, winds, brass, etc. — coordinate and balance volume and tone. When both are working well, you've got music.)

--David Dobbs, New York Times magazine: "A Depression Switch?"


Need I say more? I certainly don't enjoy thinking of my brain as a giant bowl of soup--though often it behaves that way, kind of splish-splashing around up there--but I certainly prefer the soup model to a symphony orchestra. Imagine the intrigues and infighting, in my own neurons! Imagine how they would kvetch about the chief neurons, behind their backs! And if there are brass players in my brain, I don't want to know about it (sorry, Eric and others, just kidding haha!!!!) Etc. etc. And that last line: "When both are working well, you've got music"? In your dreams, maybe.
