Researching Psilocybin's Effects on Depression - Dr. Rosalind Watts

TL;DR

Psilocybin research for depression, initiated by Robin Carhart-Harris and David Nutt, studied 20 people with treatment-resistant depression. The treatment reduced ruminative thinking by increasing brain connectivity, providing a temporary "window of opportunity" for change. 17 of 20 participants improved for at least three months, but most relapsed without integration and follow-up sessions.
