psychedelics and the wire

the wire is your brain learning — strengthening what it uses, pruning what it doesn't. the honest claim: in animals, psychedelics briefly loosen that wire and spur it to regrow, reopening windows that normally close, before it resettles. ~10 minutes, narrated by alice. watch the wire loosen and grow as she goes.

education + harm reduction. not medical advice, not encouragement. mostly evidence from mice.

the wire is you0:00 · 1/8

your brain is a network of links. the ones you use get stronger; the ones you don't get pruned. that's the wire — learning, made physical. it's hebbian: cells that fire together, wire together. it's how a child soaks up a language, and why it's harder later. everything here turns on one honest claim — in animals, psychedelics briefly loosen this wire and spur it to regrow, then it resettles. this is neuroscience, not advice, and not encouragement. i'll hold that line the whole way.

blue = the wire · green = new spines budding · amber = a reopened window. read-aloud uses your browser's voice; captions carry it either way.

// the honest ledger

  • almost all the strong rewiring evidence — spine growth, reopened windows, the trip-length scaling — is in mice and cells. no one has directly imaged psychedelic-driven synapse growth in a living human.
  • the human clinical evidence is promising but early and contested — the leading head-to-head trial (2021, NEJM) found psilocybin no better than an SSRI on its primary outcome.
  • no classic psychedelic is FDA-approved for any psychiatric condition; MDMA-assisted therapy was rejected (FDA complete response letter to Lykos, Aug 2024).
  • real risks: a personal or family history of psychosis or bipolar is a recognized contraindication (manic-switch risk); HPPD is rare but real; serotonergic and cardiac cautions exist.
  • psilocybin, LSD, MDMA, DMT are federally Schedule I; state frameworks (Oregon, Colorado) are supervised/decriminalized, not retail-legal, and vary.
  • this is education and harm reduction — not advice, not encouragement. if you're considering anything, talk to a qualified clinician and know your local law.
