Researcher: The biological cause of mental illnesses, the pharmacological and neurobiological effects of treatments, including psychedelic drugs in both high and microdoses.

All posts are my own view and not a medical advice.
Was interviewed by Double Blind Magazine about the mushrooms extend lifespan hype.

They wrote a delightful piece about how much mushroom was given.

To quote them "That’s a fuckton of mushrooms for 95% of people".

I wonder about how the last 5% are doing?

Was the Life-Extending Psilocybin Study All Hype?
One academic says yes. PLUS an interview with an Onanya, AI generated DMT visuals, and psilocybin's impact on shame.

Psilocybin as an longevity drug? Not really!

I wrote a piece in @theconversation.com about why this claim is way out of proportions.

What shifts in our brain when our consciousness shifts? On Sept 8-9, we will explore this question at ESI-SyNC 2025 - with exciting talks, posters and discussions on the neural dynamics of altered consciousness, from psychedelics to breathwork, near-death experiences and meditation.

One more clip from my interview with @mikaelpalner.bsky.social.

In this one, he outlines a neurological definition for a psychedelic "microdose" according to binding occupancy at the serotonin receptor.

And, of course, what that means.

Really feeling the #wcbr, if you are around join us for the panel on micodosing tomorrow afternoon.

New research will be presented 🏂🏻

With president Trump hitting hard on science in the US, I want to let all my fellow US researchers know that Danish foundation provides quite a lot of postdoctoral and sabattical funding for visiting US citizens.

Reach out if you want to know more or collaborate while this goes down.

Are you thinking of measuring synaptic plasticity in the living rat brain? Maybe after psychedelic-induced neuroplasticity, as David E Olson suggests in his recent commentary in the American Journal of Psychiatry

Check out our SV2A images using [18F]SynVest-1

This is a great review of novel measurements of functional connectivity.

But how would you explain "structurally informed functional connectivity" to a lay person?

Give me your best shot 😀

A #ScienceReview from last year highlights the growing recognition of the complex cognitive capacities of #rats and its implications for how they are treated in scientific contexts.
The complex affective and cognitive capacities of rats
For several decades, although studies of rat physiology and behavior have abounded, research on rat emotions has been limited in scope to fear, anxiety, and pain. Converging evidence for the capacity of many species to share others' affective states has...

Do serotonergic psychedelics (like LSD, psilocybin, and 2C-B) all induce the same acute changes in brain activity? Our research in rats says they have some common features but also some distinctly different ones. The images below are from our newest preprint.

Klemens Egger analyzed the effects of pharmahuasca on whole-brain metabolism in rats. Interestingly, while the combination of harmine and DMT increased the levels of DMT in the brain significantly, we could measure 5-HT2A occupancy. Additionally, all conditions increased thalamic activity. #dmt

Last year, we used 5-HT2A PET (see my previous post) to establish science-backed psilocybin microdosing in rats based on human occupancy data from Madsen et al. (2019). We proved that microdosing of psilocybin induces behavioral and neurobiological changes in rats! www.nature.com/articles/s41...

Moving to a new lab is fantastic. 🐀 Reconnecting the cables, installing the machines and taking photos through a plastic bag is challenging 🤔

In 2008, Matthias Herth produced [18F]MHMZ, a PET tracer I love. My lab uses it extensively to map the 5-HT2A receptors in living rat brain and measure occupancy of psychedelics, like psilocybin below. Don't tell me 1mg/kg is not enough ;)

How will the world look in 25 years if my research turns out to be a breakthrough?

That question was posed to me by Third Ear Studio and Denis Rivin 🔹🔺🔸. In their latest series "2049". We're talking about mental illnesses and psychedelic substances.
