A new preprint that revives the theory of continous attractors that may be surprising to you! Despite their mathematical fragility, we show that they are functionally *robust*. No wonder we see approximate continuous attractors in neuroscience often. arxiv.org/abs/2408.00109

🧠🗣️ Ever stumbled over your words, realizing only after speaking them outloud? Your brain might not have followed the plan. New preprint on the neural ensemble organization of speech motor plans and what it means for speech BCIs doi.org/10.64898/2026.… 1/10

@KordingLab it may be always 10 years ahead; receding goal post problem will be with us forever.

Emulating a whole brain at credible quality happens when? Definition: predict behavioral, neural activity, and perturbation results in out of domain settings.

I've been a happy customer of @TheBrainTech product since 2015 or before, using the free tier which had basic cloud sync function. I finally upgraded to the PRO version and paid $200+ and I can no longer use the basic sync function... am I doing something wrong?

If you are at #cosyne2026 come see poster [2-152] Dynamical archetype analysis: Autonomous computation. Ábel Ságodi is presenting how you can compare dynamical systems at behaviorally relevant timescale while keeping the interpretability!

Happy to share that our new paper is out in Nature Communications with Zoe Ashwood, @IntlBrainLab, and @jpillowtime! We study how animals switch between internal decision-making states in non-stationary environments using a GLM-HMM framework. nature.com/articles/s4146…

@paperpile I'm getting "you're offline" state often these days. What could be going on? If I refresh the paperpile page on Chome, it works again.

How can I accelerate breakdown of caffeine in my body? I will need to increase CYP1A2 (P450) activity (without smoking). Vigorous exercise over 30 days was shown to increase it up to 70%? pubmed.ncbi.nlm.nih.gov/1394840/

Learning a lot while preparing for a lecture on RNNs for neuroscience.

scDiffEq offers a principled framework for studying dynamics in single-cell data. For most datasets, it can run on your laptop (e.g., Apple Silicon) or T4 GPU (free in colab). 📄 Paper: nature.com/articles/s4225… 💻 Code: github.com/scDiffEq/scDif… 📚 Docs: scdiffeq.com With: Anders Rasmussen, @RuitongLi3, @KleinLabHMS, @getz_lab, and @lucapinello. @Harvard @Schmidt_Center @broadinstitute

How does a stem cell "decide" its fate? Development requires both reliability (consistent cell types) AND flexibility (diverse outcomes from identical progenitors). Cells achieve this by dynamically tuning deterministic drift and stochastic diffusion. New in @NatMachIntell: scDiffEq models state-dependent drift AND diffusion, improving fate prediction by ~8% over SOTA. scDiffEq also enables genome-wide in silico perturbation screens and reveals temporal gene dynamics. 🧵nature.com/articles/s4225…

The research labs you can join through INDP range from systems neuroscience, computational neuroscience and clinical neuroscience, to neocybernetics, neuroethology, and natural intelligence. To learn more about the culture and value, check out: fchampalimaud.org/about-cr

We seek motivated applicants from all areas of neuroscience, as well as physics, math, computer science, electrical/biomedical engineering, and related quantitative backgrounds. English is the working language. It's an American-style graduate program in Europe.

Applications are now open for the International Neuroscience Doctoral Programme (INDP) at Champalimaud Foundation, Lisbon, Portugal. Deadline for application: Jan 31, 2026 fchampalimaud.org/champalimaud-r… The programme includes an initial year of classes + three lab rotations.

One advantage of monosemantic, sharply-tuned, grandmother-cell, axis-aligned, neuron-centric representation as opposed to polysemantic, mixed-selective, oblique population code is that it can benefit from evolution. Genes are good at operating at the cell level. #neuroscience
