Interesting, but fMRI only documents blood flow to areas of the brain. Everything else is extrapolation. Suggesting that psilocybin induces neuroplasticity is probably going too far with these results. Nonetheless, more and more research seems to show benefit for some people.

I am re-reading a book by Ram Dass in which he writes that his frequent use of psychedelics did not create the lasting impact he was seeking. He found it through a commitment to love and selflessness.
