The way you describe it isn't really how it works. It doesn't rewire your brain in an active sense so much as introduce elasticity for your brain to rewire itself. This is especially useful when the brain has gotten itself into a doom loop of depression or anxiety. The psilocybin allows you to break out of the doom loop and start your brain on the path of healthy development.
That sounds great. However, anything that causes anatomical brain chages that persist after a month, with a single dose, would be, by me, considered unacceptably risky. I'm not saying that it's by default considered bad, both you and the paper are talking about positive changes, and that's good. I'm saying, "risky," as in, I don't know what negative effects haven't been identified and I'd need a much more complete understanding before I'd be willing to try it.
Most of the positive effects are in reported well-being, but I really want to see more cognitive tests. The tests on cognitive flexibility is a great start, but we really need a barrage of tests here: mathematical ability? Short-term *and* long-term memory? Spatial thinking? Are there *any* cognitive functions that are negatively affected here? It's important to understand this with anything that has this type of long-lasting effect.
