How MDMA resensitizes the brain
…in mice, MDMA can reopen the critical period for social learning after it should have closed permanently.
In 2019, neuroscientist Gül Dölen’s laboratory at Johns Hopkins University in Baltimore, Maryland, found that the psychedelic drug MDMA resensitizes the brains of adult mice so they can learn from their social environment in a way that’s normally reserved for adolescence… we think that what feels like an altered state of consciousness, common to all psychedelics, is what it feels like to reopen critical periods. You can find this in the language people use to describe their experience with these drugs. They refer to returning to a state where they are living in the present moment, noticing everything and being really sensitive to the world.
