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

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/s41467-0…

Identifying the factors governing internal state switches during nonstationary sensory decision-m...

Nature Communications - The factors governing mouse decision-making strategies in changing environments remain unclear. Here the authors use a 4-state input-driven model to show that past...

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/1394…

Foreign compound metabolism capacity in man measured from metabolites of dietary caffeine - PubMed

Caffeine is sequentially metabolized by cytochrome P4501A2 (CYP1A2), N-acetyltransferase (NAT) and/or xanthine oxidase (XO). In the present study the activity of these three enzymes was estimated...

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

Melanie Mitchell's keynote reminds us that it is not easy to evaluate intelligence (AI, babies, animals, etc) and benchmarks can be VERY misleading. #NeurIPS2025
