The study reveals that psilocybin binds to serotonin receptors (specifically 5-HT2A) and triggers a rapid burst of dendritic spine growth. In psychology, we call this neuroplasticity—the brain’s ability to physically rewire itself. I’ll admit, there were months when anxiety made it hard to find stillness, even in my practice. But when I sat with a moderate dose, I didn’t just experience a “trip.” I felt a literal cognitive restructuring. Old anxious loops softened, and calmer, more resilient pathways began to form in real time.

It reminded me of The Tower in the Tarot. That card isn’t just about destruction; it’s about the necessary collapse of outdated structures so new growth can emerge. Paired with The Star, it speaks to healing, hope, and the quiet realignment of inner energy. In my midwifery work, I’ve watched bodies reorganize after trauma. The brain does the exact same thing here.

I’ll be honest—I was nervous at first. But seeing the mechanistic explanation align with my own experience made everything click. If dendritic spines are literally sprouting through serotonin receptors, lasting psychological change isn’t mystical. It’s biology finally catching up to our capacity to heal. Has anyone else felt that “rewiring” during a session? I’d love to compare notes.
