THE NEUROSCIENCE OF DMT - Andrew Gallimore PhD

from Chasing Consciousness · host Freddy Drabble

How are DMT experiences neurologically different to hallucinations? How does DMT alter the world modelling of our brains? What evidence is there that the brain is receiving information on DMT rather than modelling it?In this episode we have the extraordinary neuroscience of DMT to discuss, one of the most powerful mind altering substances on the planet. We discuss the history of research into its effects; relevant neuroscience; research into the mystical experiences it induces; the statistical significance of repeated, highly specific yet unearthly places and entities reported by experiencers across eras and cultures; experiments that extend the DMT experience for longer periods of time; the metaphysical implications if any; and finally we consider the mind bending possibility that the otherworldly creatures and realities experiencers repeatedly encounter could be actual realities connecting with our brains via DMT.Fortunately to navigate these mysterious results and ideas, we have chemist, computational neuroscientist and author Andrew Gallimore as our guide. Gallimore has written 16 scientific papers and three books including, “Reality Switch Technologies: Psychedelics as Tools for the Discovery and Exploration of New Worlds”, “Alien Information Theory: Psychedelic Drug Technologies and the Cosmic Game”, and his brand new book, “Death By Astonishment, confronting the mystery of the world’s strangest drug” which we’ll be focussing on in this episode.What we discuss:00:00 Intro.08:30 How DMT binds to the brain.09:50 Receptors are like a cell’s perception organs.14:25 The cascading of electrical patterns across neurones.16:50 The big differences between DMT and 5meoDMT.18:50 Hierarchical structure of model processing.
