Brain activity patterns during meditation shift after a psilocybin-assisted retreat, especially when open-monitoring meditation is practiced. Using functional MRI and a topological data analysis method (Mapper), researchers compared experienced meditators who received psilocybin or placebo over five days. The psilocybin group showed a link between positive derealization—an altered perception that can foster insight—and a greater geometric distance between open-monitoring meditation and resting-state brain activity, as measured by optimal transport distance. This suggests that combining psilocybin with open-monitoring practice enhances meta-awareness and insight. The findings point to possible brain markers for synergistic effects between mindfulness and psychedelics.
