06.10.26 PD Dr. Dr. Daniel VilligerAre the Ethical Challenges of Psychedelic-Assisted Therapy Exceptional?
Psychedelic-assisted therapy is often portrayed as exceptional because of psychedelics’ unusual features. This talk asks whether those features justify exceptional normative treatment and examines four prominent areas of debate: informed consent, therapists’ personal psychedelic experience, clinical trial design, and heightened patient vulnerability. I argue that while three of these presumed cases of psychedelic exceptionalism are either not exceptional after all or not sufficiently justified, enhanced vulnerability during psychedelic sessions may require genuinely distinctive safeguards.

Could repeated psychedelic microdosing carry risks for heart tissue? Antonin Rouaud examines concerns about stimulation of the serotonin 5-HT2B receptor and its association with fibrosis, drawing comparisons with known cardiotoxic substances. The talk identifies a safety question requiring further research rather than establishing the risk of a particular microdosing regimen.
About the speaker
Antonin Rouaud co-authored research reviewing microdosing, cardiac fibrosis and valvular disease with Abigail Calder and Gregor Hasler. He presented this topic at the 2024 ALPS Student Forum hosted with PROZ.

The Effects of Psilocybin on Brain EntropyDrummond McCulloch · 50 min
About the talk
What is brain entropy, and do different measures describe the same phenomenon? Drummond McCulloch examines research on acute psilocybin effects in brain imaging, where studies have often used distinct metrics.

Psychedelics and Neuroplasticity: Not from Drugs Alone?Abigail Calder · 1 h 2 min
About the talk
Animal research suggests that psychedelics can enhance neuroplasticity, but how well does this translate to people? Abigail Calder examines the influence of experience, environment and behaviour on plasticity. The talk asks what may be missed when therapeutic change is explained as a drug effect alone.
