🚨Friends, we’re happy to share that our book is available for pre-order! 🎉
We aimed to cover all the foundations of the topic in an accessible manner for a large audience.
It could help set up a bachelor-level curriculum on the topic.
Pre-orders are very key for the fate of books: shorturl.at/Dxbif

Why do some people lose memory faster with age? A mega-analysis of 13 longitudinal datasets (3,700+ adults, 10,000+ MRIs) shows that memory decline tracks brain atrophy, especially in the hippocampus, and that these links strengthen with age, but not APOE status: www.nature.com/articles/s41...

1/6 New preprint 🚀 How does the cortex learn to represent things and how they move without reconstructing sensory stimuli? We developed a circuit-centric recurrent predictive learning (RPL) model based on JEPAs.

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.

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:

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)
