I am thrilled about this new preprint of ours! Using 7T fMRI of the spinal cord we uncover two different spinal response components – phasic and tonic heat responses – that map differentially onto superficial and deep layers of the dorsal horn! 🔥Long thread upcoming!🧵 www.biorxiv.org/content/10.1...
Ultra-high-field fMRI reveals layer-specific responses in the human spinal cord
Developments in functional magnetic resonance imaging (fMRI) at ultra-high field (UHF) now allow for insights into human brain function at mesoscopic scale. However, similar progress has not been achi...

Almost missed that this is out! Former postdoc Liz Necka led this long overdue FMRI study formally comparing two types of pain modulation: Placebo analgesia & predictive cues. TLDR: these are NOT the same! Placebo analgesia reduced cue effects, & brain mechanisms were nearly all dissociable. 1/4
New in #JNeurosci from Necka et al: External cues and treatments shape expectations about pain in different ways, and their mechanisms distinctly influence how people experience pain. https://doi.org/10.1523/JNEUROSCI.0050-25.2025

The first study from my postdoc is now up as a preprint 👏🏻 we combined #EEG and #VR in a cool task (feat. 🦊) finding that lateralised ongoing pain affects predictive responses to phasic pain on the same side of the body.

US Wissenschaftler*innen nach Europa locken?
Besser:
Strukturen in den USA solidarisch kritisieren und Bedingungen hier gründlich verändern.

Wenn @amreibahr.bsky.social verhindert ist, darf ich den Newsletter füllen. Also habe ich mir mal die Rhetorik der ganzen Forderungen angesehen, Forschende aus den USA zu uns zu holen. Mein Gastbeitrag in #ArbeitInDerWiss #IchBinHanna open.substack.com/pub/arbeitin...

Here is a recap of the Ukraine situation, for those choosing to reject propaganda and continue seeking truth:
December 1994, Ukraine agrees to give up its nuclear arsenal in return for security guarantees from the US, UK, France, China and Russia.

That! I have also seen cases of papers that dumped DCM methods onto their existing fMRI data without a well-defined question.. using it to infer just any directionality and in too large model spaces, giving no specific insight. The strengths of the method are definitely elsewhere.
DCM is just a framework for estimating the statistical evidence for state-space models, which are fitted to time series data using Bayesian methods. Each model is a hypothesis. So the question is, what's the right data and models for your question. [1/5]

That's why I think we should go in the opposite direction. Empower junior scientists. Don't make junior PIs beg for grant funding in competitions decided by the opinions of senior scientists. Don't make them postdocs subordinate to their supervisors.

I posted the last version of this too hastily. I wasn't satisfied with the art so I added more yeast. Now I think I'm done with it.
