!!!! Last couple weeks before we run interviews for this! Please share around if you know people wanting to do multidisciplinary research at the intersection between interoception and addiction.

New @bodybrainbehaviour.bsky.social preprint, and this is a big one for the lab: @teresaberther.bsky.social did the deepest of dives into #gut-brain coupling with MEG and HD gastrography.

A figure showing that non-invasive transcutaneous vagus nerve stimulation (tVNS) modulates Pavlovian bias in a state-dependent manner. A milkshake vs. water load reduces hunger and these changes are associated with the effects of tVNS on Pavlovian bias.

Last preprint 🎶(of the year).

If vagus nerve stimulation alters motivation by amplifying internal signals, then bodily states should matter. Using milkshake vs. water loads, we show that tVNS-induced changes in Pavlovian bias are dependent on hunger. #neuroskyence 🩺

Very excited to introduce InteroMap, a new bodily mapping tool designed to measure how we subjectively experience our bodily sensations, what we call interoceptive phenomenology 🧵👇

Just got to read this. Very important! Been saying for years we need to stop measuring interoception at baseline, and yet in addiction most of the research in clinical pops is just that. It is challenging to go beyond baseline measures, but not doing that is a waste of precious resources!

🫡💪

By the end of it we will have a better understanding of the role of interoception in addiction and how to target it in therapeutic processes. I probably spent more time than it is healthy or reasonable to get this grant, so happy to get it funded on my first try!

Throughout the project we will use state of the art measures of #interoception, and rely on a superb team of world-leading collaborators in both addiction and interoception. I will of course be hiring at PhD and Post-doc level pretty soon.

The clinical component will track physiology and bodily sensations associated with craving in clinical populations, and use this information to develop novel individualized treatments targeting bodily processes in a randomized controlled trial.

The experimental leg will measure whether bodily processes associated with craving drive intravenous alcohol self-administration and tobacco consumption in the laboratory and test whether this can predict escalation in substance use.

Incredibly excited to announce I have been awarded an @erc.europa.eu Starting Grant for the project BodyCrave! This project tackles the bodily processes underlying alcohol and tobacco craving, from bench to bedside. #ERCStG

This LEAP program is very weird. Why do they call them performers first of all? 😅

Nice! Would you mind adding me?

Please share! Last few days to apply for this PhD position on nociception and interoception in alcohol use disorder, together with Pierre Maurage at UC Louvain. Also looking for strong candidates on social cognition and respiratory interoception: jobrxiv.org/job/uc-louva...

Over time, these interoceptive changes become associated with alcohol expectancies, and could participate in risk for alcohol misuse and disorder. If your body responds more pleasantly to alcohol, or don't experience certain bodily sensations, you may be more likely to persevere.

Considering that this was isolated to interoceptive performance (and not extero), and that changes in interoception correlate with subjective alcohol effects, this points towards the idea that alcohol impacts bodily states to generate an interoceptive experience of intoxication.

So that's really cool, we ask participants to say how they think they'd feel after having a few drinks, quite some time before the actual experiment. And it turns out those expectancies are predicted by changes in metacognitive interoception.

And again, subjectively alcohol effects of light-headedness are predicted by changes in interoception (and importantly, not exteroception!). The same happens with anticipated alcohol effects, this time measured a couple weeks prior to the study.

Quite interestingly, there's sensitive null evidence for a main effect of alcohol on intero and extero performance. However, there's a range of individual variability in that effect, as usual.

New preprint for a Stage 2 RR: Re-examining acute alcohol effects on interoception using the Heartrate Discrimination task! A partial replication of my previous studies, this time with a nice exteroceptive control osf.io/preprints/ps...

That's very interesting! We are working on some cool EMA tools to study interoception, been thinking about adding a physiological component to it, but it's as you said complicated.

Something is printing!

APA does this thing where I get to write about it a bit in lay terms for a quick summary: growkudos.com/publications... Looking forward to combining this during my Marie Curie, with EEG, Pavlovian to Instrumental Transfer and if everything goes well, interoceptive conditioning!

New paper out! This thing took ages, but here it is, some good evidence that aversive conditioned stimuli can trigger attentional responses without awareness of stimulus-outcome contingencies. psycnet.apa.org/doiLanding?d....
