🧵 Endogenous DMT: What Do We Really Know?
Two recent papers shed new light on endogenous DMT, its biosynthesis, regulation, and function:
📄 Exploring DMT: Endogenous Role and Therapeutic Potential – by @psychedmt
📄 N,N-Dimethyltryptamine (DMT) in Rodent Brain: Concentrations, Distribution, and Recent Pharmacological Data – by Steven Barker
This thread summarizes key findings.

These studies challenge the idea that DMT exists in only trace amounts and has no biological role.

Let’s dive in. ⬇️🧵

CPCR Director @FredBarrettPhD quoted in @AP “It’s been incredibly difficult to study ibogaine in the U.S. because of its known cardiotoxicity... If the executive order can pave the way for doing objective, scientific research with this compound, it would help us understand whether it is truly a better psychedelic therapy than others.” https://t.co/rwBlMuJiX7

Is forgetting the secret to intelligence? An epic roundtable with Michael Levin, Karl Friston, Mark Solms, Richard Watson, and Alexey Tolchinsky break down why selective forgetting is absolutely essential for cognition, agency, and building a coherent sense of self.
A fascinating deep dive into the mechanics of the mind! https://t.co/zmDsc5Sutm

Adult brains operate near a “critical point” of balanced excitation/inhibition, enabling more coordinated rhythms and greater efficiency.

Action potentials are only one layer of brain computation.

New discovery! Different anesthetics all seem to push the brain into unconsciousness in the same way: Activity is destabilized and dominated by slow waves. This could block signals.

Emerging evidence shows higher cognition relies on rhythmic electric fields—acting like "radio waves"—to enable large-scale organization, executive control, and energy-efficient analog computing.

I read this recently: https://t.co/uHMlSzFV0J It says 2A blocker studies often "over-dose the blocker" and thus lose specificity to 2A. Could this apply here? https://t.co/mr1DiR52Rp

There's some wisdom here, perhaps. Absolute outcomes like response and remission may well be better post-approval. On this front, it's almost as if Compass stacked the deck against efficacy so as to "play the game" well. That's a clear contrast vs the Lycos story. It's a good point to end on.

[Robin Carhart-Harris @RCarhartHarris]

Same point here. I think this is the main takeaway. To say it simply: on face value, Compass are still on track for approval, having played the game well.

@MillerLabMIT @Jeanvaljean689 Hey @MillerLabMIT, what’s your take on Selen Atasoy’s harmonic decomposition method?

[Sheila Macrine, Ph.D. @MacrinePhD]

Time to de-anthropomorphize the mind. New research proposes a unified framework viewing cognition as a biological spectrum—from single cells to complex mammals. Intelligence isn't just neural; it's embodied life-regulation and information processing found across all living systems. 🧠🦠 https://t.co/TSiYuy4jwu #DiverseIntelligence
