*Ahem* What I did on my lockdown (part 1). I taught myself the basics of audio production, & recorded a silly song about my favourite imaging modality. I humbly present "The MRI song" in the hope it's a brief distraction from the general hideousness. youtu.be/zfYINee1VA4

Haven't done one of these for quite a while, but I regret to inform you that I've hideously butchered another classic song in the name of making some weak jokes. I present: Psychedelic Therapy: The song. Have a great time at #PS2025 everyone! youtube.com/watch?v=4V2sGwB0…

This extraordinary psychedelic precision functional mapping dataset is now fully/freely available to all! All the info to access & use it in a newly published Nature Scientific Data Resource: rdcu.be/epxe7 Thanks to the incredible team who created it - Subha S, Rick R, Ginger N, Demetrius P, Nick M, to name a few.

After a high dose of psilocybin, the brain desynchronizes at a massive scale, causing loss of our sense of self, time, and space. This may drive the burst of plasticity caused by psychedelics. The next day, brain activity has largely returned to normal, but an echo remains – a reset of circuits critical to the sense of self. Our study is out today in @Nature nature.com/articles/s41586-0…

🚨New paper alarm🚨 Excited to share our new publication that breaks new grounds for #psychedelic medicine: the first data on #psilocybin’s effects in any neurodegenerative disease, specifically psilocybin for the treatment of #Parkinson's disease! It was a phase 1 feasibility and tolerability study on 12 patients with all the usual limitations of such studies, e.g. lack of control condition. The treatment consisted of 2 psilocybin sessions, the first with 10mg and then a larger 25mg dose 2 weeks later. As usual psilocybin was coupled with therapy. The study's primary objective was to treat the mood dysfunction associated with Parkinson's. We got the usual large and positive treatment effects as other psilocybin trials: three months after the last dose MADRS significantly improved by 9.3 points, corresponding to 1.0 standardized mean difference (SMD; i.e. large effect). Anxiety, as captured by the Hamilton Anxiety Rating Scale, also significantly improved by 3.8 points, corresponding to 0.7 SMD. More surprisingly, Parkinson's symptoms also improved post-psilocybin! We captured Parkinson's with the standard MDS-UPDRS assessment, , and patients significantly improved in all domains at every post-treatment timepoint (!!!) with mostly moderate-to-large effect sizes. Benefits persisted at the 3 months post last dose timepoint. No serious adverse events (AEs) occurred. As expected, most AEs occurred during psilocybin sessions (anxiety, nausea, headache) and were self-resolving and transient. Even better than the paper that we are already running the follow-up phase 2 trial! If you know anyone in the Bay area who could be interested, please let them know: psychedelics.ucsf.edu/#Studi…. Full paper: tinyurl.com/y9rcp7mk Celebrating with @EllenBradleyMD, @thebandlab and the whole @UCSF's @TrPR_Program crew! 🙏🫂❤️

Neuroscience shows neural oscillations sync with music via neural resonance theory. Not just prediction—brain-body dynamics embody musical structure, driving perception. This may amplify psychedelic experiences, resonating with ASC. nature.com/articles/s41583-0…

Beyond happy to share this study with you - Ashley and the team have really exceeded all expectations. Computational modelling of drug effects on multi-domain interoception!
1/ We can measure interoception in many aspects, but can we actually manipulate it? I’m excited to share our new study, which shows that blockade of peripheral beta-adrenergic pathways improves cardiac and respiratory interoception in unique ways! 🧵👇biorxiv.org/content/10.1101/…

Hey kids, want to hear me babbling somewhat coherently for 35 mins about cannabis, psychedelics, addiction & more? Yes? What, really? Well OK... I had a lovely time talking to Dr David Hardy on the Hardy Brain podcast, and you can listen to it here too: thehardybrain.ca/podcasts/th…
