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! 🧵👇 https://t.co/1zLNmHTsZv

Clemens spitting fire in 1984. We agree - hence our creation of the heart rate discrimination task!

1/ To explore or to exploit? I’m excited to share my new preprint with @TobiasUHauser and @micahgallen, correlating variations in cortical microstructures with individual differences in exploration-exploitation behaviours, using a gamified task! https://t.co/xzYERidD2F

@TobiasUHauser @micahgallen 5/ In line with previous studies led by @DubMagda and @TobiasUHauser, we found that subjects increased their value-free random exploration in trials where exploration is beneficial (long horizon), compared with trials in which exploration is not beneficial (short horizon)💡

Excited to share our latest paper, using gamified tasks for computational psychiatry developed by @TobiasUHauser and colleagues to explore brain behavior correlates in decision making!

Stomach–brain synchronisation is associated with poorer mental health https://t.co/pwuMzNsdlv insightful commentary by Edwin Dalmaijer on our recent study!

In common parlance, ‘being in touch with your body’ is often used positively. However, in a recent study, Banellis, Rebollo, and colleagues show that better stomach–brain synchronisation is actually...

Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection.

Interoception—the sensing and perception of the internal viscera—is widely cast as a transdiagnostic mechanism linking brain–body interaction to mental illness. Prevailing models propose that altered...

Greater stomach-brain connection is associated with worse mental health. This is opposite to the belief that being ‘more in tune with your body’ improves mental health.

Our new preprint compares naïve baselines, network models (incl. PLRNN-based SSMs), and Transformers on 3x40‑day EMA+EMI datasets. PLRNNs gave the most accurate forecasts, yielded interpretable networks, and flagged “sad” & “down” as top leverage points. https://t.co/9trDupOR4A

Information Geometry is about ***dual geometry***: Build your own information geometry by choosing (1) manifold M, (2) metric g (3) affine connection ∇, torsion-free Dual connection is simply ∇*=2∇^g- ∇ using Levi-Civita connection ∇^g See my pinned tweet for tutorial.
