"There's a stomach inside my brain"

I think Tyler is so insightful and smart and clever and just... amazing, but he doesn't even know it. This lyric caught my attention because there is actually something called the "enteric nervous system" and it is in your stomach. Some scientists refer to it as "The Other Brain". Literally. Something like 50% of your body's serotonin and 90% of your body's dopamine LIVES in your stomach, in that "other brain". These are chemicals often associated with depression and anxiety disorders. I just found that so interesting. I know he was saying there's a stomach inside his brain, not vice versa, but it's still interesting to me, even if he didn't mean for anyone to make that connection at all.
