INTRO: The human brain can change—but usually only slowly and with great effort, such as when learning a new sport or foreign language, or recovering from a stroke. Learning new skills correlates with changes in the brain, as evidenced by neuroscience research with animals and functional brain scans in people. Presumably, if you master Calculus 1, something is now different in your brain. Furthermore, motor neurons in the brain expand and contract depending on how often they are exercised— a neuronal reflection of “use it or lose it.”
People may wish their brains could change faster—not just when learning new skills, but also when overcoming problems like anxiety, depression, and addictions.
Clinicians and scientists know there are times the brain can make rapid, enduring changes. Most often, these occur in the context of traumatic experiences, leaving an indelible imprint on the brain.
But positive experiences, which alter one’s life for the better, can occur equally as fast. Think of a spiritual awakening, a near-death experience or a feeling of awe in nature.
Social scientists call events like these psychologically transformative experiences or pivotal mental states. For the rest of us, they’re forks in the road. Presumably, these positive experiences quickly change some “wiring” in the brain.
How do these rapid, positive transformations happen? It seems the brain has a way to facilitate accelerated change. And here’s where it gets really interesting: Psychedelic-assisted psychotherapy appears to tap into this natural neural mechanism.
Those who’ve had a psychedelic experience usually describe it as a mental journey that’s impossible to put into words. However, it can be conceptualized as an altered state of consciousness with distortions of perception, modified sense of self, and rapidly changing emotions... (MORE - details)
