Just because scientists have identified something happening between my ears doesn't make it any less a part of my personality. They're just different types of description. If someone is accused of prostitution, they can't defend themselves by saying, "No, it wasn't prostitution, see what happened was, they gave me money and in exchange I made X-Men 3." They've just described the exact same situation using different terms. You aren't any less culpable because it can also be described in terms of neurons firing.
The same goes for articles with this recurring theme: "Learning this skill physically changes your brain." They should be studied for their almost supernatural ability to create an absolute vacuum of meaning. It turns out, when you learn anything your brain physically changes. That's because your brain is where your learning lives.
If I've done my job correctly, your brain will have changed a lot by the time you're done reading this.
