Episode notes
DMT Is Produced Broadly, Not Only Pineal
- DMT is synthesized from tryptophan via the enzyme INMT across many tissues, not just the pineal.
- Recent rat microdialysis shows surprisingly high brain DMT levels and production beyond the pineal.
DMT May Rise During Dying And Be Neuroprotective
- DMT can protect neurons from hypoxia in cell cultures.
- Measured brain DMT spikes at death in rats suggest a link to near-death phenomena.
Entities Direct The DMT Experience
- Gallimore proposes DMT gates access to directed intelligence rather than purely internal hallucination.
- He describes entities as actively commandeering the brain's world-building machinery.
