The Basement: Andrew Gallimore | DMT Didn't Take You Somewhere New — It Unlocked What's Always There
"What he found is that if you deprive neurons of oxygen and added some DMT to the mix, the neurons survived much longer. A neuroprotective. It's neuroprotective, and it's actually a particular receptor, um, um, called the sigma-1 receptor. So then you think about this, oh, wait a minute, what happens during the dying process? Well, your cardiovascular and respiratory systems start to collapse. Your brain is starved, gradually more and more starved of oxygen. Now, this is precisely the time when, you know, if you do come back, right? If you don't die, this is precisely the time when you need as much DMT in your brain as possible to help protect your brain."
University researchers induced cardiac arrest in rats and measured surging DMT levels in dying brains. Biochemist Edie Fresca discovered DMT binds sigma-1 receptors to protect oxygen-starved neurons much longer than controls. Gallimore theorized endogenous DMT production spikes during dying to preserve brain tissue, potentially explaining both the neuroprotective evolutionary purpose and near-death visions.

About this episode

Host AJ interviewed Cambridge-trained neuroscientist Dr. Andrew Gallimore about his 30-year study of DMT, the world's most powerful naturally occurring psychedelic. Gallimore, author of Death by Astonishment, presented his controversial theory that the beings millions report meeting on DMT may be real sentient entities rather than hallucinations. He detailed his development of DMTX with researcher Rick Strassman, an extended-state intravenous protocol that maintains stable breakthrough experiences for hours instead of minutes, now available at a legal Caribbean research facility. The conversation explored why DMT brain activity differs from other psychedelics, collapsing into impossible coherent order rather than random entropy, and why human brains construct alien worlds they never learned to build. Gallimore described the lockout phenomenon where entities explicitly deny access to regular users for years despite identical dosing, and a case where an entity terminated a woman's vision mid-infusion despite DMT still flowing into her brain. He revealed new collaborative work with consciousness theorist Donald Hoffman applying mathematical conscious agent theory to DMT, proposing the molecule gates access to normally imperceptible dimensions of a consciousness-first reality. The discussion covered the evolutionary purpose of endogenous DMT, its neuroprotective role in dying brains, connections to alien abduction experiences, and experimental protocols like the blue-yellow screen test designed to prove DMT entities track external variables subjects cannot know.
