Now published @commsaicomp.nature.com with @neural-reckoning.org We: 🤖 Define a taxonomy of neural network architectures (here 128 unique structures) 🦾 Train > 25,000 models on different navigation tasks #RL 🧠 Link each architecture's behaviour to its memory dynamics doi.org/10.1038/s444...
A taxonomy of recurrence. We defined a family of neural networks for exploring questions in neuroscience and machine learning. Here each network is represented by three circles joined by different connections (short, coloured lines). Networks are joined by longer, pale grey lines if they differ by one connection. Moving from left to right takes us from the simplest to the most complex network.

Nice! I made a similar argument re the value of small “toy” models in #neuroscience doi.org/10.53053/WUS...

Not playing around: Why neuroscience needs toy models
Amid the rise of billion-parameter models, I argue that toy models, with just a few neurons, remain essential—and may be all neuroscience needs.

That’s exactly the right question! What is the smallest / simplest model for your phenomenon of interest. Some recent work, cited in the article, shows that very small models can be surprisingly powerful. And often we may be far above the lower bound, which then hinders interpretability

2. Brains are massively complex, but if our goal is to understand them, then building scale models may not be the best approach. In physics, many breakthroughs have come from abstracting away complexity, as this article highlights! doi.org/10.1111/ejn....

Marcus Ghosh @marcusghosh.bsky.social · 23/12/2025
Thanks for reading the article! 1. The multi-billion parameter model discussed in the article was developed by Meta but then fine-tuned by neuroscientists (for research). This could become more common, or neuroscientists could start to train their own "foundation" models from scratch.
