Excited to share that the main work of my PhD has been published!

We found that having control over pain makes expectations more precise, and changes pain perception. This is accompanied by activation changes in the PAG, SMA and ACC.

You can read the full version of the paper here: rdcu.be/eQy6X
Controllability changes pain perception by increasing the precision of expectations
Nature Communications - Control over pain changes how intense it is perceived. Here, the authors show that this effect results from increased expectation precision with control, which changes...

Once again a reminder that so-called "neural representations" and codes are formal constructions of the *observer*, usually built to summarize the observer's measurements. Signatures of neural activity, not internal states of the system.

Empirically, more extensive project descriptions do not affect the eventual decision anyway:

detectibly impact their proposal rankings."

One example of how multiplexing might be implemented in the brain was shown in the great work by Thomas Akam with Dmitri Kullmann, a decade ago.

The papers are cited well but the general multiplexing idea never really took the field by storm as much as it deserved

This kind of stuff is why I say that I worry that the tools of neuroscience are not properly vetted
“Our findings challenge the conventional focus on low-dimensional coding subspaces as a sufficient framework for understanding neural computations, demonstrating that dimensions previously considered task-irrelevant and accounting for little variance can have a critical role in driving behavior.”
Neural dynamics outside task-coding dimensions drive decision trajectories through transient amplification
Most behaviors involve neural dynamics in high-dimensional activity spaces. A common approach is to extract dimensions that capture task-related variability, such as those separating stimuli or choice...

It feels like the converastion about manifold dimensionality is back, so I thought I'd share a paper that explains nicely why measuring the "embedding dimensionality" of a manifold (e.g., counting PCs) can be very different from its actual "intrinsic dimensionality (DoFs)

I think almost all scientific projects should be planned carefully. And I think an app can dramatically improve that. So I wrote an app for that (free for now, if you can fund this let me know). I tested it quite a bit (>8000 users in beta so far). try it: planyourscience.com

How do we make sense of scientific literature that is growing explosively to the point where no-one could read all the relevant papers, and is contaminated with fraudulent and LLM-generated papers? I think that science isn't currently equipped to deal with this, and we need to. #science #metascience
