Research on the neuroscience of consciousness—from addiction to insight.

Findings indicate an “arrested development” in brain activity related to cognition in young men with a history of frequent cannabis use.

This preliminary look across consciousness-modifying techniques from anonymous online reports is a call for rigorous laboratory studies to validate mind-manifesting effects.

Even “microdoses” of psychedelics increase the complexity of brain signals, a measure thought to be related to consciousness. Interestingly, this effect was absent in other psychoactive substances tested, even at higher doses.
