New study published: Psilocybin-assisted mindfulness training modulates self-consciousness and brain default mode network connectivity with lasting effects (Patreon)

Full text.  Nice to see an entirely different team, in a different country, essentially reproduce the earlier published results from Griffiths, et al. 2017  Specifically,  they found (in a double blind, placebo controlled study) that psilocybin induced "oceanic self-boundlessness" (which is essentially the feelings or experience of oneness with the universe, timelessness, and bliss) correlated with desirable changes in attitudes about life, self, social behavior, mood, and spirituality even months after the experience (4 month follow up).   They also speculate that an experience of ego dissolution may further imply cognitive reappraisals, reifications, self-inquiry, or insights and contribute to enduring psychological changes.  Participants were primarily in middle adulthood and already heavily engaged in meditative practices, and yet the psilocybin-treatment group still reported a significant beneficial effect.

For dosage they used 315ug/kg which is approximately equivalent to about 2.2 to 3 grams of dried cubensis mushrooms for an average person.
